An energy-saving clustering strategy of hybrid network of sensors and mobile CR nodes

摘要：

　　Cognitive radio(CR)networks can be combined with sensor networks,it can not only share traffic of sensor networks but also reduce the transmission delay because of the spectrum advantage,thus can perform monitoring tasks better.To improve the reliability of the mixed network and energy efficiency of sensors,this article achieves sensor networks clustering based on the mobility and distribution of CR nodes.The CR nodes act as cluster head and undertake the task of relay between clusters.In every cluster,the sensor nodes are divided into several coverage subsets,and their working duration are scheduled by the distribution of energy.Simulation results showed that the strategy proposed can reduce the network energy consumption and delay,guarantee the quality of monitoring,and extend the network lifetime effectively.
