Abstract
Most existing on-demand mobile ad hoc network routing protocols continue using a route until a link breaks. During the route reconstruction, packets can be dropped, which will cause significant throughput degradation. In this paper we introduce the Packets Received Time (PRT) to predict the link state, that is, if a particular node is soon to go out of transmission range. The Prediction Algorithm together with our PRT approach enhances the performance of the existing Ad-hoc On-Demand Distance Vector (AODV) protocol. The new approach is compared with original AODV in CBR and TCP traffics using various scenarios. The simulation results showed that our scheme is more efficient, reliable and improves throughput of the Ad-hoc network.
