... approximate routes to each destina- tion rather than exact routes. In [12, 13], each node main- tains approximate (or less accurate) information to faraway destinations, since the updates from faraway ... path to the destination uses its rout- ing table to forward each data packet towards the destina- tion. The advantage of this strategy is that routes are adapt- able to the d...
