... approximate routes to each destina-tion rather than exact routes. In [12, 13], each node main-tains approximate (or less accurate) information to farawaydestinations, 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 dynamically changing ... means that fewer route recalculations are requiredduring data transmission. The disadvantage of this strategy isthat each intermediate node must store and maintain routinginformation for each...
