DHAC Based Routing in Wireless Sensor Network with Asymmetric Links

In Wireless Sensor Network (WSN), various routing strategies have been adopted to prolong the network lifetime. Clustering is the important technique in comparison to all the other existing routing techniques. Proposed algorithm adopts the hierarchical structure for cluster formation and selecting cluster head in distributed approach. In this paper, clustering of nodes is carried out by considering the asymmetric communication links between nodes. Energy consumption in proposed technique is reduced and hence lifetime of the network is improved. The Simulation is carried out in MATLAB7.9 and the obtained result verifies that proposed algorithm increased network as compared to the existing routing protocols.
