Improve the Performance of Adaptive Sleep Scheduled Wireless Sensor Network

The conventional methods of improving the performance of wireless sensor network focus on proposed algorithm mechanism to increase the packet delivery ratio, reduce the delay and so on. In this paper, firstly we propose an adaptive sleep scheduled scheme to reduce the energy consumption of the whole network. Based on this, we introduce weight w to measure the importance of data. We assume that the faster important the data is transmitted to sink node, the better the performance of whole network is. Applied the scheduling policy, system sleep optimum is impossible. The simulation shows that the performance has increased compared with full connect network.
