在动态环境中执行数据传感和数据传播的服务操作越来越成为无线传感器网络的重要任务。因此，增加网络寿命是本研究的主要贡献。我们提出了一种新颖的基于棋盘的功率感知自适应路由（PCAR）协议来支持无线传感器网络中的不动性管理。这项工作中最重要的设计挑战是降低网络能耗，从而最大限度地延长网络寿命。我们的 PCAR 协议利用面向矢量的传播、功耗决策和多路径路由协议来引导传播数据到其目的地。此外，簇的属性在 PCAR 中组合，形成基于棋盘的簇传感器网络中的簇板。簇头节点和睡眠节点的交替使用提高了能源效率。适时分而治之的多路融合机制减缓并平衡能量消耗。最后，性能分析表明 PCAR 协议实现了能源效率。
Increasingly, the services operations which perform data sensing and data propagation in a dynamic environment are important tasks of wireless sensor networks. Therefore, increasing the network lifetime is the main contribution of this investigation. We propose a novel power-aware chessboard-based adaptive routing (PCAR) protocol to support immobility management in wireless sensor networks. The paramount design challenge in this work is to scale-down the network energy consumption, thus maximizing the network lifetime. Our PCAR protocol utilizes vector-oriented propagation, power-consideration decision, and multi-path routing protocols to guide the propagating data to its destination. Moreover, the properties of the clusters are combined in the PCAR to form the cluster-plates in a chessboard-based clustered sensor network. The alternate usage of cluster-head nodes and sleep nodes increases energy efficiency. The opportune divide-and-conquer multi-path fusion mechanism slows down and balances energy consumption. Finally, a performance analysis shows that energy efficiency is achieved by the PCAR protocol.
