SCCP:self-adjusting of circle coverage protocol in wireless sensor networks
SCCP：无线传感器网络自调节圆周覆盖协议*

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.
