In wireless sensor networks (WSNs), the clustering architecture balances the energy consumption of the sensor nodes as compared with the flat network architecture. The cluster heads which are nearer to the sink node spend more energy than other cluster heads since it relays the packets in addition to its essential functions. The mobile sinks avoid such an energy hole scenario in sensor networks. Several schemes address the mobility of sink to balance the energy consumption of sensor nodes in the last few years. Those schemes give their attention to either sink path determination or sojourn location determination calculations. Therefore an Energy Efficient Optimal Sojourn Location of Mobile Sink (E2OSLMS) scheme is proposed in this paper to determine the optimal sojourn location of the mobile sink in an energy-efficient manner. In this proposed scheme, the mobile sink moves on a spiral path among clusters and stays in each cluster for a limited time. The sojourn locations are optimized using a fuzzy rule base in each cluster upon the arrival of the mobile sink. The simulation results outperform the proposed scheme as compared with the other two related schemes in terms of energy consumption of nodes and lifetime of the network.

在无线传感器网络 (WSN) 中，与平面网络架构相比，集群架构平衡了传感器节点的能耗。离汇节点较近的簇头比其他簇头消耗更多的能量，因为除了其基本功能外，它还中继数据包。移动接收器避免了传感器网络中的这种能量空洞场景。在过去的几年中，有几种方案解决了接收器的移动性以平衡传感器节点的能量消耗。这些方案关注汇路径确定或逗留位置确定计算。因此，本文提出了一种移动接收器的节能最优逗留位置（E2OSLMS）方案，以节能的方式确定移动接收器的最优逗留位置。在这个提议的方案中，移动宿在集群之间的螺旋路径上移动，并在每个集群中停留有限的时间。在移动信宿到达时，使用每个集群中的模糊规则库来优化逗留位置。与其他两种相关方案相比，仿真结果在节点能耗和网络寿命方面优于所提出的方案。
