This paper analyzes the hierarchical routing protocol - LEACH, and based on LEACH proposes a new data transmission routing protocol-LEACH-EEMH for wireless multimedia sensor networks. The protocol improves the selection method of cluster head and the formation method of clusters, at the same time improves the method of communication between the cluster head and the base station. The algorithm takes the residual energy of the node, the distance from the cluster head to the base station, the data transmission delay, and the error rate into accounts. The simulation results show that the algorithm can reduce network energy consumption, prolong the lifetime of the network and ensure reliable delivery of multimedia data and real-time data transmission.
