The MONARCH project is sponsored by DARPA under the Polymorphous Computer Architecture Program. MONARCH is developing a revolutionary chip distinguished from other PCA systems by unifying two radically different architectures into a single flexible VLSI device. MONARCH architecture combines the DIVA PIM architecture, developed by USC/ISI as part of the DARPA-sponsored Data Intensive Program, and HPPS (High Performance Processing System) developed by Raytheon with IRAD funds. We previously presented the motivation for merging these two architectures (HPEC 2002). We have since developed the detailed specifications for the micro architecture of the MONARCH chip and also the software environment, run time system and on-chip communication network. Furthermore, we have completed the evaluation of several benchmarks and we have shown that the MONARCH architecture is capable of achieving a very high stability factor that allows the MONARCH architecture to process data at near peak throughput speeds.

BAD plays an important role in the evaluation of survivability of crew and components in a vehicle under fire. Survivability and vulnerability analysis codes (e.g., MUVES) require an input of BAD characteristics of the armor for each threat projectile. This data is currently generated by conducting laboratory experiments in a standard set-up in which each threat projectile is fired on the actual armor and the BAD pattern is captured on witness plates. Conducting survivability analyses of vehicles in the design phase, before the armor is actually built, poses a challenging problem. To solve this problem, we have come up with an innovative approach to determine BAD characteristics by conducting virtual experiments of the standard set-up. We do this by conducting physics-based three-dimensional (3-D) computer simulations with the CTH wave code. We obtain BAD characteristics for impacts of kinetic energy rods and shaped charges on metal and ceramics plates, including some yawed rod impacts. An additional advantage of these simulations is that they provide important details of the debris field that are difficult to obtain in laboratory 235 experiments. The expected impact of this work would be to improve the timeliness, accuracy, and cost of survivability analyses for Army’s decision makers.

EFW is a host-based, centrally controlled firewall system consisting of network interface cards and the Policy Server software. A network consisting of EFW clients and a Policy Server is set up in the Advanced Network Laboratory at the Naval Postgraduate School. The Smartbits packet generator is used to simulate realistic data transfer environment. The evaluation is performed centered on two main categories: performance analysis and security capability tests. TTCP program and a script written in TCL are used to perform throughput and packet loss tests respectively. The penetration and vulnerability tests are conducted in order to analyze the security capabilities of EFW. Symantec Personal Firewall is used as a representative application firewall for comparing test results. Our study shows that EFW has better performance especially in connections with high amounts of encrypted packets and more effective in preventing insider attacks. However, current implementation of EFW has some weaknesses such as not allowing sophisticated rules that application firewalls usually do. We recommend that EFW be used as one of the protection mechanisms in a system based on the defense-in-depth concept that consists of application firewalls, intrusion detection systems and gateway protocols.

This paradigm assumes nodes have location awareness and can measure the received signal strength of incoming transmissions. Thus, nodes can discover the pathloss in their environment. This information along with other information relevant to the node is combined into a node’s state that is disseminated throughout the network. This state information not only supports all nodes discovering the network’s topology but provides the very information that makes network management, network engineering, traffic engineering, and spectrum management feasible. This contribution of this summary is a brief description of how node state routing (NSR) paradigm enables these management and engineering capabilities.

This goal for economic prosperity is linked to globalization and this information technologies that tie the world’s economics and occupants together. A primary means of communication and information sharing is the Internet. The USA (US) is currently the world’s largest user and proponent of the Internet. The massive sharing of information is crucial for US economic development and expansion and is in line with the American concept of itself. However the Internet as a method of sharing information has a dark side. The information accessible level of communications linkages and sheer interconnectiveness of the World-Wide-Web leaves the US vulnerable to violent non-state actors using the Internet. These groups will use the Internet and its architecture to command & control collect information target possibly attack access and disseminate the results of their activities with minimal exposure to traditional means of national intelligence collection and detection. The architecture is allowing violent non-state actors to attack the US over its own systems and designs. This paper will look at this phenomenon the scope of the problem draw conclusions and make some recommendations.

This paper uses a novel threshold signature scheme with the features of ad hoc sever selection and dynamic group membership to secure the service provision phase of the rSerPool application in MANET. Our distributed and survivable threshold signature scheme can tolerate single point of failure and Byzantine attacks. Its ad hoc 237 server selection increases service availability and decreases service latency. Our signature scheme provides essential authentication service in rSerPool and can be further used as part of distributed certificate authority in MANET.

In this paper, we evaluate the performance of the distributed Beacon protocol as the topology changes and as a function of the election metric under various conditions. We propose the ‘domain age’ as the primary election metric to maintain more stable domains than ‘lowest ID’, yet requires no more information be collected. We quantify the increased stability using OPNET simulations. We believe that a combination of domain age, node degree and domain strength will provide the Beacon protocol with the ability to maintain good domains in future battlefield networks.

Moses, Bruce D.; Jan. 2004; 82 pp.; In English Report No.(s): AD-A432929; No Copyright; Avail: Defense Technical Information Center (DTIC) This monograph examines whether the Army’s information collection efforts are supporting the goal of full spectrum dominance and whether these are in harmony with the concepts of network centric warfare. Full spectrum dominance and network centric warfare are central themes in Department of Defense and Army transformation literature and both require information collection and an understanding of the role of cognition empowered by networking for success. More specifically, it examines whether Army collection efforts are focusing too heavily on collection for combat operations and leaving it unable to fully exploit the access to adversary systems during stability operations. This study found that the institutional Army is not fully supporting the goal of full spectrum dominance or network centric warfare but is still myopically investing heavily in efforts to defeat the adversary’s conventional capabilities with standoff collection technology and is not creating the organizational, systems and technical architectures necessary to leverage the power of a fully networked force.

In order to position the photon beams accurately, a slow global orbit feedback system has been developed. The dominant causes of orbit motion at the ALS are temperature variation and insertion device motion. This type of motion can be removed using slow global orbit feedback with a data rate of a few Hertz. The remaining orbit motion in the ALS is only 1-3 micron rms. Slow orbit feedback does not require high computational throughput. At the ALS, the global orbit feedback algorithm, based on the singular valued decomposition method, is coded in MATLAB and runs on a control room workstation. Using the MATLAB environment to develop, test, and run the storage ring control algorithms has proven to be a fast and efficient way to operate the ALS.

A reintegration protocol increases system survivability by allowing a node that has suffered a fault to regain state consistent with the operational nodes. The protocol is verified in the Symbolic Analysis Laboratory (SAL), where bounded model checking and decision procedures are used to verify infinite-state systems by k-induction. The protocol and its environment are modeled as synchronizing timeout automata. Because k-induction is exponential with respect to k, we optimize the formal model to reduce the size of k. Also, the reintegrator’s event-triggered behavior is conservatively modeled as time-triggered behavior to further reduce the size of k and to make it invariant to the number of nodes modeled. A corollary is that a clique avoidance property is satisfied.

Over 100 environment and analysis models are integrated into the menu-based tool. EWB, which was developed for and under the guidance of the NASA Lewis Research Center, is built atop the Module Integrator and Rule-based Intelligent Analytic Database (MIRIAD) architecture. This allows every module in EWB to communicate information to other modules in a transparent manner from the user’s point of view. It removes the tedious and error-prone steps of entering data by hand from one model to another. EWB runs under UNIX operating systems (SGI and SUN workstations) and under MS Windows (3.x, 95, and NT) operating systems. MIRIAD, the unique software that makes up the core of EWB, provides the flexibility to easily modify old models and incorporate new ones as user needs change. The MIRIAD approach separates the computer assisted engineering (CAE) tool into three distinct units: 1) A modern graphical user interface to present information; 2)Adata dictionary interpreter to coordinate analysis; and 3) A database for storing system designs and analysis results. The user interface is externally programmable through ASCII data files, which contain the location and type of information to be displayed on the screen. This approach provides great flexibility in tailoring the look and feel of the code to individual user needs. MIRIADbased applications, such as EWB, have utilities for viewing tabulated parametric study data, XY line plots, contour plots, and three-dimensional plots of contour data and system geometries. In addition, a Monte Carlo facility is provided to allow statistical assessments (including uncertainties) in models or data.

Large distributed arrays of deployable configurable sensors cooperating to achieve system-level goals may provide the solution for such problems 241 whether acting as independent networks or as agents gathering localized information to aid large assets. The primary challenge of dynamic allocation of network assets (DANA) is the cost of computation and communication of global optimization and real-time configuration of individual sensors. Scaling of network size generally yields an exponential increase in optimization computation and a prohibitive need for communication bandwidth for scheduling of individual sensors making such approaches of limited real-time use. This paper presents the novel methodology of Self-Organizing Networks (SONets) where small sensors with local decision capabilities and overall system performance knowledge yield an emergent behavior aimed at maximizing system information in a communication-constrained architecture while eliminating (or reducing) the need for sensors to be actively scheduled. Preliminary results demonstrate promising performance in a multi-target/ multi-sensor environment. The SONets methodology is based on sensors making local decisions on which mode to operate in including data collection broadcast, etc. based on perceived value of expected return and thresholding with the capability of adaptively self-organizing Sensors update learning indices (adaptive weights) based on expected return and observation of overall system knowledge. The result is an emergent behavior that may be supervised and altered through general broadcasts from a centralized unit.

The Future Force must be highly mobile, agile, and lethal to ensure its dominance in the future battlefield. This dominance is reliant on the ability to see and understand first (situational awareness). Persistent and pervasive sensing and processing, coupled with greatly increased speed of information flow, information assimilation, and decisive action, at and between all levels of our force, are necessary to fulfill this requirement. The USA Army is most vulnerable in urban terrain. This highly constrained, complex environment presents a significant challenge to US forces, particularly dismounted infantry and military intelligence because opposing force activity is readily masked or obscured by background noise (commerce, schools, religious activity etc.). This paper proposes an intelligent interaction between the digitized dismounted units and military intelligence, for the significant benefit to both.

However, this evolution has been dominantly bottom-up and technology- driven, with new emerging technologies supporting the traditional concept of decision making as a basically rational process. In an effort to reconceptualize decision making, this paper follows a top-down approach, starting with a new conceptual framework and then exploring the technologies and tools that can support it. To this end, the paper proposes four major conceptual shifts: a pragmatic shift from problems in the mind to problematic situations in the world, a constructive shift from passive decision making to active sense making, a normative shift from accuracy and certainty to plausibility and transparency, and a technical shift in our understanding of technology as enabler to technology as transformer of human activity. These shifts are in harmony with current theoretical trends in DSS and related disciplines, e.g., the growing emphasis on multiple perspectives in DSS, on multi-agent systems in Artificial Intelligence, on distributed cognition in psychology, and on sense making in organization science. By focusing our attention on the collective, distributed, and constructive character of cognition, the framework that results from these shifts provides a useful way of thinking about DSS. Furthermore, ideas from science and technology studies portray a tightly interwoven picture of technologies and their social and organizational context, which is very different from the traditional view of technologies as mere tools. Brought to the realm of DSS, this calls for a fresh look at the relationship between information technologies and decision-making processes.

Existing multirobot task allocation algorithms treat tasks as simple, indivisible entities. However, when dealing with complex tasks, the structure and semantics of the tasks can be exploited to produce more efficient team plans by giving individual robots the ability to come up with new ways to perform a task, or by allowing multiple robots to cooperate by sharing the subcomponents of a task, or both. In this paper we detail a method for efficiently allocating a set of complex tasks to a robot team. The advantages of explicitly modeling complex tasks during the allocation process is demonstrated by a comparison of our approach with existing task allocation algorithms in an area reconnaissance scenario. An implementation on a team of outdoor robots further validates our approach.

Over the course of our five year DARPA/ONR/SPAWAR sponsored project in Computational Neuromechanics and its application to robotics, we have begun to answer the questions, how, why, and when, in a mathematically rigorous and biologically testable manner. Addressing these simple questions has simultaneously helped advance animal motion science as well as accelerated progress in the design and control of useful legged robots.

A Voronoi diagram may be generated by any finite set of points in a plane. For mobile robot control each point in the plane represents a Voronoi classifier. The classifiers are used to generate Voronoi regions. As a robot comes into a Voronoi region the classifier will act as a control input; providing a new waypoint for the vehicle to follow. The robot moves towards the new waypoint unless interrupted by an obstacle or wall. The robot will get a new waypoint from the classifier in the robot’s current Voronoi region. This process continues until the robot has terminated at a desired position (goal) or runs out of power.
