Cluster-based load balancing multi-path routing protocol in wireless sensor networks

For extending the lifetime of sensor networks by improving load balancing in wireless sensor networks, the cluster-based multi-path routing protocol, CLBM, has been studied in this paper. In CLBM, theory of space and time localization has been introduced in the process of cluster head reselecting, cluster node will select the cluster head according to residual energy and the nearest distance between the node and the event center area. The cluster head can reduce the energy consumption of itself by sending the data to the nearest node of multi-path routing; while for cluster node, consulting with its child node can reduce the energy consumption of whole networks. It can be demonstrated by simulation experiments that CLBM protocol basically achieves the load balancing of networks so as to extending the network lifetime efficiently.
