Abstract

In wireless sensor networks (WSNs), the energy hole problem is a key factor affecting the network lifetime. In a circular multi-hop sensor network (modeled as concentric coronas), the optimal transmission ranges of all coronas can effectively improve network lifetime. In this paper, we investigate WSNs with non-uniform maximum transmission ranges, where sensor nodes deployed in different regions may differ in their maximum transmission range. Then, we propose an Energy-efficient algorithm for Non-uniform Maximum Transmission range (ENMT), which can search approximate optimal transmission ranges of all coronas in order to prolong network lifetime. Furthermore, the simulation results indicate that ENMT performs better than other algorithms.

摘要

在无线传感器网络 (WSN) 中，能量空洞问题是影响网络寿命的关键因素。在圆形多跳传感器网络（模拟为同心光环）中，所有光环的最佳传输范围可以有效地提高网络寿命。在本文中，我们研究了具有非均匀最大传输范围的 WSN，其中部署在不同区域的传感器节点的最大传输范围可能不同。然后，我们提出了一种用于非均匀最大传输范围的节能算法 (ENMT)，它可以搜索所有光环的近似最佳传输范围，以延长网络寿命。此外，仿真结果表明，ENMT 优于其他算法。
