A wireless monitoring network is an effective way to monitor and transmit information about railway infrastructure conditions. Its lifetime is significantly affected by the energy usage among all sensors. This paper proposes a novel cluster-based valid lifetime maximization protocol (CVLMP) to extend the lifetime of the network. In the CVLMP, the cluster heads (CHs) are selected and rotated with the selection probability and energy information. Then, the clusters are determined around the CHs based on the multi-objective optimization model, which minimizes the total energy consumption and balances the consumption among all CHs. Finally, the multi-objective model is solved by an improved nondominated sorting genetic algorithm II. The simulation results show that, compared with two other strategies in the prior literature, our proposed CVLMP can effectively extend the valid lifetime of the network as well as increase the inspected data packets received at the sink node.

最大限度延长铁路基础设施无线监控网络使用寿命的最佳通信协议


无线监控网络是监控和传输铁路基础设施状况信息的有效方式。其寿命很大程度上受到所有传感器的能源使用情况的影响。本文提出了一种新颖的基于集群的有效寿命最大化协议（CVLMP）来延长网络的寿命。在CVLMP中，簇头（CH）根据选择概率和能量信息进行选择和轮换。然后，基于多目标优化模型在CH周围确定聚类，从而最小化总能耗并平衡所有CH之间的消耗。最后，采用改进的非支配排序遗传算法II对多目标模型进行求解。仿真结果表明，与现有文献中的其他两种策略相比，我们提出的CVLMP可以有效延长网络的有效寿命，并增加汇聚节点接收到的检查数据包。
