Abstract
In this paper, an improved AODV - PWAODV (Piggyback and Weighted neighbor stability Ad hoc On-demand Distance Vector routing) protocol with lower route cost and smaller delay is presented. In the algorithm we introduce a piggyback mechanism and weighted neighbor stability algorithm. Essentially, the route cost can be reduced greatly by the use of piggyback mechanism and the link stability algorithm decreases the delay because of ensuring the robustness of the network topology. Finally, by comparison in the simulation via NS2, our newly-mentioned protocol could acquire better route cost and delay performances.
