Abstract:
This work investigates the behavior of the Ad Hoc On-Demand Distance Vector (AODV) routing protocol in situations of link failures due to the mobility of nodes in wireless ad hoc networks. The AODV performance is compared when the failure repair happens locally from the node before the link break to the case where the repair is performed from the source node for four metrics: throughput (as packet delivery fraction), overhead, average packet delivery delay and average hop count, the last being only used to validate throughput and delay analyses. From the scenarios studied, it was observed that the throughput and delay for source repair have better performance, while overhead was better for local repair in sparse networks.
