A reliable routing organization method in heterogeneous sensor network

The heterogeneous sensor network is a widespread network of sensors in our life. In the heterogeneous sensor network consisting of ordinary nodes and senior nodes, senior nodes are used for clustering-head to collect and transmit information to base station, the reliability of the senior nodes impact on the reliability of the whole network. In order to improve the reliability of the senior nodes puts forward senior nodes to be classified into common senior nodes and candidate senior nodes. When common senior nodes malfunction, candidate senior nodes with mobile function will substitute common senior nodes to perform work. Another, common senior nodes are organized into double-loop structure to enhance running reliability. The simulation shows that this organization method can improve energy efficiency, reduce imbalance energy consumption.
