Method for balancing layered energy consumption of wireless sensor network facing to perception events

Abstract

The invention provides a method for balancing layered energy consumption of a wireless sensor network facing to perception events, which relates to a method for saving the energy consumption for the wireless sensor network and solves the problem of balancing the energy consumption of the wireless sensor network which is deployed intensively under the drive of the perception events. A basic system comprises intensively-deployed wireless sensor network nodes, cluster head nodes determined through an election strategy, the perception events randomly happening in the network, and base station nodes deployed on the network edge; on the basis of the perception events happening in a network deployment environment, a plurality of layered sensing collections centering on the cluster head nodes are constructed, and according to the level in which each node is positioned in the sensing collections, the rest energy and the concrete loading condition of each transmission link in the collections, corresponding task scheduling and transmission path selection are performed to balance the energy of each node; and simultaneously, centering on the base station nodes, an optimized data transmission path among the sensing collections is established, and the energy consumption of the entire network is further balanced and the network life cycle is prolonged by dynamically changing a transmission cycle of cluster head data.
