Abstract: We designed a High energy Node driven Ad hoc On-demand Distance Vector routing protocol(HN-AODV) for wireless ad hoc networks. The design objective is to prolong the network lifetime. To achieve this goal, in our protocol design, the path to reach a destination is biased towards those paths constituent of nodes with high energy for balancing energy consumption in the network. Our protocol embeds this high energy node driven feature into the on-demand path discovery process of an existing routing protocol AODV. Detailed protocol design descriptions were provided Simulation results show that our protocol can greatly prolong the network lifetime as compared with AODV. Moreover, our idea can also work well with other existing on-demand routing protocols for wireless ad hoc networks.
