Wireless sensor network clustering routing method based on harmony search algorithm

Abstract

The invention discloses a wireless sensor network clustering routing method based on a harmony search algorithm. The method comprises the following steps: (1) global information transmission and convergence: acquiring the global information, and transmitting the global information to an aggregation node; (2) the aggregation node performs optimization calculation and configuration of network clustering routing of the entire sensor network through the global information; (3) a common sensor node monitors, collects and processes application information, processes the application information into a data packet, and forwards the data packet to a cluster head node, and the cluster head node performs data fusion and sends the data packet to a next hop cluster head node; and (4) the next hop cluster head node adds its own dump energy information to the data packet after receiving the data packet, and continues to forward the data packet to the next hop cluster head node according to the optical routing in the data packet. By adoption of the method disclosed by the invention, the problems of unreasonable member node allocation, uneven power consumption of the cluster head nodes of a wireless sensor network are solved, the energy efficiency of the network is improved, and the life cycle of the network is prolonged.
