Abstract :
The distributed routing protocol is widely used in wireless sensor networks. But it is mainly designed for homogeneous networks and also has the disadvantages of irrationality of choosing cluster head and unbalanced energy consumption of nodes. Through theoretical studies, a new protocol of the cluster multi-hop transmission (CMHT) for heterogeneous sensor networks is proposed. The algorithm selects cluster head nodes by calculating Weight-value and transfers data by using nodes in cluster and cluster-head multi-hop transmission manner. Finally, the protocol is simulated by using MATLAB. The simulation result shows that this improved protocol could suitably form clusters, better improve the energy balance of a node, and effectively prolong the survival time of the entire networks.
