Rubaina Takhi . Reduction of Routing Overhead in Wireless Sensor Network with Modified AODV-TP (Constant Packet Size). Communications on Applied Electronics. 3, 8 ( December 2015), 1-4. DOI=10.5120/cae2015652002
Power management is essential in Wireless Sensor Network because the nodes are very small in size having a small battery and that too of limited life. The routing algorithms for it should satisfy the features of optimization of energy consumption. Ad hoc On Demand Distance Vector routing protocol has been modified, this algorithm has been analyzed named as modified AODV-TP (Threshold Power) and is highlighted in detail. The theme is that only those nodes are chosen as neighbors of nodes during RREQ (Route Request) phase that are directed towards destination. Also, threshold is set for all the nodes. If the power of the node is less than threshold, it will not acknowledge Route Reply (RREP) packet. The alternate route with second lowest minimum distance will be selected to forward the packet. The comparison is done between two protocols in terms of routing overhead and average remaining energy of nodes and delay with variation in packet. The proposed algorithm turns out to be better in terms of power conservation.
