Abstract: Based on the research on the clustered Ad Hoc routing protocols, this paper proposed to improve CGSR protocol under the conditions of balanced energy consumption and prolonged lifetime. Energy consumption was reduced by cutting down the message transmition. Energy restriction of Clusterhead reduced the impact of excessive energy consumption on the network life. NS-2 simulation results indicate the lifetime of network increases when new protocol CBSR is used.

摘要： 通过对Ad Hoc网络分群路由协议的研究，从平衡节点能量消耗和增加网络生命周期角度出发，提出了CGSR的改进型路由协议CBSR。CBSR通过减少信息转发次数，有效地减少了能量消耗。使用群首能量限制降低了因群首能量消耗过快对网络整体寿命的影响。通过NS-2仿真实验，论证了改进后的协议具有更长的生命周期。
