In recent years, the development of micro-manufacture, communication and battery technologies has reduced the size of that, we can compose the sensor, wireless communication, and date processing units into a sensor node which is the basis of Wireless Sensor Networks(WSNs). WSNs contains a large number of sensor nodes. Since the energy of nodes is limited, and environment is not easy to get energy, the energy efficiency is a key design that needs to be enhanced in order to improve the life-time of the network.
We use different cluster cutting strategies were proposed to deal with the large geographical differences, balance the energy load in the cluster and avoid the long-distance transmission between internal cluster nodes. In addition, in the cluster first transmission to the base station path selection, we use the Ant-Colony Optimization (Aco) finds the shortest path from the cluster-heads to the base station, that can be avoided long-distance intra-cluster data delivery. Simulation results demonstrate our strategy are efficient.
