WSN中基于5色标记的分簇路由研究

Research on Cluster Routing Based on Five Colors Label for Wireless Sensor Networks

分簇路由可以通过数据汇聚节省传感器网络的能量,但现有的分簇路由也存在一些不足之处,为此提出基于5色标记的分簇路由协议。该协议选择满足条件的最大度节点作为簇头,可以最大限度地让簇头覆盖更多的节点,从而减少生成的簇数,减少簇间的通信量;选择在通信半径内的节点作为簇成员,减少簇内的通信量,这样对整个网络的通信量都会有所控制,从而达到能量高效的目的;另外通过簇头的转移可以尽量地维护网络的稳定状态,减少了频繁生成簇的能量开销和网络时延,是传感器网络中一种能量高效的路由协议。

cluster routing can save energy of wireless sensor networks throng data aggregation,but the current cluster routing have some disadvantage,so a cluster routing based on five colors label （CRBFCL）for wireless sensor networks has been proposed in this paper.CRBFCL selects the nodes which meet the conditions and have the most degree as cluster headers,that can let cluster headers cover the most nodes and reduce the number of clusters,reduce the traffic between clusters;and chooses the nodes which within the communication radius as cluster members, that can decrease the traffic within cluster, the entire network traffic will be controlled so as to achieve the purpose of energy efficiency; and can maintain the network stability by cluster header transferring, decrease energy consumption and network delay caused by continually creating cluster, it is an energy efficient cluster routing protocol in WSNs.
