Node energy consumption balancing method for wireless sensor network

Abstract

The invention discloses a node energy consumption balancing method for a wireless sensor network. The method includes the steps of 1, acquiring the distance from each node in the network to a base station; allowing the base station to calculate optimal hop count and optimal cluster number according to the network scale, and allowing each node in the network to calculate the distance from itself to the base station; 2, determining an energy threshold of the current cycle; 3, establishing clusters, namely reserving each candidate cluster head have residual energy larger than the energy threshold as a cluster head, and adding non-cluster-head nodes to different clusters; 4, transmitting stably, namely allowing the nodes in each cluster to transmit data to the cluster head in a single hop manner, and allowing the cluster head to forward the data to the base station in a combined manner of single hop and multiple hops. The node energy consumption balancing method for the wireless sensor network has the advantages that energy consumption is balanced for the nodes and the service life of the network is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of wireless communication networks, in particular to a method for equalizing energy consumption of nodes in a wireless sensor network. Background technique [0002] The low power consumption, low cost, self-organization and distribution of wireless sensor networks make it an important technology for information acquisition. However, the limited resources make the application of wireless sensor networks face great challenges. Reducing energy consumption and prolonging network life cycle are important research directions in the field of wireless sensor networks. As an important technology to reduce energy consumption and prolong network life cycle in wireless sensor networks, topology control method has become one of the hotspots and difficulties in the field of wireless sensor network research in recent years. [0003] Existing topology control methods mainly focus on two aspects: node power control and hier...
