无线传感器网络(WSNs)中的能量感知路由研究了低容量电池限制下延长WSNs网络寿命的关键问题。然而，目前的大多数工作都没有解决热点问题，即由于汇聚节点附近的功率耗尽而导致的汇聚节点的隔离。在本文中，我们提出了一种解决方案，该方案结合了平面多跳路由和分层多跳路由两种路由策略。前者旨在最小化网络中的总功耗，而后者试图通过利用数据压缩来减少通信量。我们从数学上分析了该算法的功耗，并通过大量的仿真实验证明了该算法能够通过缓解热点问题来延长网络的生存时间。
Power-aware routing in wireless sensor networks (WSNs) focuses on the crucial problem of extending the network lifetime of WSNs, which are limited by low-capacity batteries. However, most of the contemporary works fail to resolve the hotspot problem, which is the isolation of the sink node due to the power exhaustion of sink close-by nodes. In this paper we propose a solution to address this issue through a hybrid approach that combines two routing strategies, flat multi-hop routing and hierarchical multi-hop routing. The former aims to minimize the total power consumption in the network, and the latter attempts to decrease the amount of traffic by utilizing data compression. We mathematically analyze the power consumption of our proposed algorithm, then we demonstrate through extensive simulations that the proposed scheme is able to extend the network lifetime by alleviating the hotspot problem.
