无线传感器网络技术是一种热门技术,在很多领域有着广泛应用。节点部署是无线传感器网络工作的关键问题,对网络的运行情况和寿命有很大的影响。规格化部署方法是节点部署方法中常用的方法。经典规格化部署方法有正方形、正三角形、菱形和等边六边形,但目前很少有人对等边六边形中非正等边六边形的部署方法进行研究。本文对非正等边六边形的部署方法开展了深入的研究,在现有的研究成果基础上,理论推导了在通信半径和感知半径具有不同比例关系时采取何种规格化部署方式最优的结论,并进行了仿真验证。
Wireless sensor network technology is a hot technology, has been widely used in many fields. Node deployment is a key issue in the work of wireless sensor networks and has a great impact on the operation and life of the network. Normalized deployment methods are common methods in node deployment methods. Classical normalized deployment methods include square, regular triangle, rhombus and equilateral hexagon. However, few researches have been done on the deployment of non-equilateral hexagons in equilateral hexagon. In this paper, the deployment of non-equilateral hexagons has been studied in depth. Based on the existing research results, the paper deduces the optimal method of normalized deployment when the communication radius and the perceived radius have different proportions The conclusion, and has carried on the simulation verification.
