A Routing Algorithm Based on Multi-hop Transmission of Intra-cluster for WSN

For wireless sensor network composed of sensors with different functions,a multi-hop intra-cluster transmission routing algorithm based on weight-value was put forward.In this algorithm,cluster-head nodes were selected by calculating weight-value according to the different energy distribution in network nodes.In the stage of stable data transmission,the multi-hop transmission of intra-cluster was adopted.Results of simulation show that the algorithm can reduce the energy consumption of cluster-head,balance the network load and prolong the network lifetime.
