无线传感器网络节点可靠性分析

Reliability analysis of wireless sensor network node

本文通过对现阶段无线传感器网络可靠性因素进行分析,对原有LEACH协议进行改进,提出了一种新的节能、拓扑可靠的簇算法ERCTNA(Energy-efficient and reliable cluster algorithm fortopology)。ERCTNA算法通过簇头辅助节点的设置和优化信息传输模式可以平衡簇头的能量负载,增加网络的拓扑可靠性。这种模式改善了传统无线传感器网络中长距离通信带来的能量过度耗损问题,有效的延长了整个网络的生命周期,提高了无线传感器网络的可靠性。

After analyzing the reliability of wireless sensor networks at the present stage , a new energy-efficient and reliable cluster algorithm for topology （ERCTNA） is proposed in this paper, which is based on the improvement of original LEACH protocol . ERCTNA algorithm can balance the energy loads of cluster heads and increase the topology reliability of the network by setting up auxiliary cluster head nodes and optimizing information transmission modes. For the wireless sensor networks, this algorithm can give an affirmative approach to the problem of excessive energy consumption in long-distance communication, extend the life cycles of entire networks effectively, and improve the reliability of networks.
