摘　　要：提出了一种高效节能的无线传感器路由协议,此协议中,传感器节点保存多条到达网关节点的最短路径,通过轮循机制选择最短路径,从而将数据传输的任务均衡地分布于多条路由路径上,避免了网络冲突,节省了节点的能量消耗。对此协议进行了详细的分析和讨论,在网络仿真环境下实现了此协议并且分析比较了此协议与LEACH和PEGASIS的性能,实验数据表明此协议比现有协议具有更好的性能,充分证明了此协议的有效性和正确性。This paper proposed an efficient and energy-saving routing protocol for wireless sensor networks. In the protocol, each sensor node stored multiple shortest routing paths to reach to the gateway nodes and employed the round robin mechanism to select one routing path so that the data transmission could be distributed evenly around the multiple paths to avoid the network congestion and to save the node’s energy. Discussed and analyzed the protocol in detail and implemented the protocol in a network simulation environment. Compared and analyzed the performances of the protocol,LEACH and PEGASIS. And the experimental data demonstrate that the performance of the protocol is better than the ones of LEACH and PEGASIS,which proves the protocol’s validity and correctness.
