摘要
提出了一种高效节能的链式分簇路由(CCR)协议。CCR协议提出了一种新的高效的双向的链式数据聚合与传输方式,在全网分簇的基础上在簇内使用此传输方式。簇头间通过路由树将采集到的数据发送到指定的唯一与基站通信的根簇头节点。仿真实验证明:CCR协议与LEACH[1]和PEGASIS[2]2种早期的路由协议相比,其网络寿命分别提高了400%和200%。
An energy-eficient chain-cluster routing（CCR） protocol for long-lived sensor network is proposed. The new and improved catenulate communication in clusters is taken when nodes sends data to cluster head（CH） based on the whole network taken sereval clusters. The CH sends data to the designated root node in a routing-tree manner to the base station. Simulation experiments demonstrate that compared with both low-energy adaptive clustering hierarchy（LEACH）and power-eficient gathering in sensor information system（ PEGASIS）, the CCR protocol can lead to the increase of sensor network lifetime （ the first node dies） by 400 % and 200 % respectively.
