Research on Performance of Unidirectional Links Routing Protocal With Different Mobility Models

In the Mobile ad hoc network, most routing protocols assume that all wireless links are bidirectional, but such assumptions may lead to sub-optimal performance in conditions of non-uniform transmit power and non-uniform background noise.

Summary:In the Mobile ad hoc network, most routing protocols assume that all wireless links are bidirectional, but such assumptions may lead to sub-optimal performance in conditions of non-uniform transmit power and non-uniform background noise. We present a scheme improved from Ad Hoc Ondemand Distance Vector (AODV), which computes routing path using backup routing table and Backtrack Route Reply mechanism when subjected to unidirectional links. Each node maintains a backup path to the source node, and when the backup path is unavailable, the node will backtrack to last hop to find the alternative path to the source. Compared to basic AODV and AODV-Blacklist schemes, simulation results show that the more unidirectional links exist the better the proposed scheme performs, and under different mobility models, the performances metric are significant difference.
