Abstract: Hierarchical routing algorithm is the most important method for prolonging lifetime of wireless sensor networks, which can not only decrease the energy consumption of the nodes, but also balance the energy dissipation of the entire network. Therefore, this paper proposes a new layer based and energy-balanced clustering protocol which was compacted energy-aware and energy-consumption-balanced. In the lower layer of the protocol, the optimal cluster of all nodes using particle swarm optimization algorithm was realized. And in the upper layer, the chief-cluster-head, which was responsible for collecting, aggregating the data of all cluster heads and sending the fused data to the base station, was selected. Simulation results demonstrated that the protocol can efficiently decrease the dead speed of the nodes and prolong the network lifetime.

 

Keywords: Energy equilibrium, Wireless sensor network (WSN), PSO, Asynchronous clustering.
