An Advanced Cluster-Based Routing Protocol for Wireless Sensor Networks with Nonuniform Node Distribution
نویسنده
چکیده
Because of the non uniform node distribution, the energy spending among nodes are more imbalanced in cluster-based wireless sensor networks. Based on this problem, in this paper, a cluster-based routing protocol for wireless sensor networks with non uniform node distribution is proposed, which includes an energy-aware clustering algorithm EADC and a cluster-based routing algorithm. EADC uses competition range to make clusters of even sizes. At the same time, the routing algorithm increases forwarding tasks of the nodes in barely covered areas by forcing cluster heads to choose nodes with higher energy and fewer member nodes as their next hops, and finally, achieves load balance among cluster heads. Theoretical analysis and simulation results show that our protocol can balance the energy spending among nodes and increase the network lifetime considerably.
