SCCP:无线传感器网络自调节圆周覆盖协议

SCCP:self-adjusting of circle coverage protocol in wireless sensor networks

为了提高节点能量的利用率,延长网络寿命,提出了一种节能的自调节圆周覆盖协议(SCCP)。协议基本思想是,基于圆周覆盖算法,在保证网络覆盖的前提下,通过休眠冗余节点提高网络生存时间。模拟实验结果表明,SCCP在覆盖率性能方面与圆周覆盖算法类似,但能有效节约节点能量,延长网络生存时间。

In order to improve the energy utilization of node,and prolong its service life,this paper proposed an energy-efficient and self-adjusting of the circle coverage protocol （SCCP）.Based on the circle coverage algorithm,the protocol could enhance the time-to-live （TTL） of network through sleeping the redundant nodes without effecting the network coverage rate.The simulation results show that the SCCP has the similar performance about the network coverage compared with the circle coverage algorithm,but SCCP can save the node energy effectively and extend the TTL of WSN significantly.
