基于IAPIT的无线传感器网络定位算法研究

无线传感器网络的应用领域涵盖军事、医疗、环保以及交通等。由于涉及到体积、功率和成本一些因素的限制,现在流行的全球定位的系统和无线传感器网络的节点定位并不配套。所以,探讨符合无线传感器网络的定位算法有着广泛的实际应用价值和非常重要的理论价值。研究了无线传感器网络中IAPIT的定位算法,就不一样的节点通信半径和锚节点比例,仿真比较探讨APIT算法和IAPIT算法的性能。从实验可以看出,IAPIT算法和APIT算法比较,大大增加了定位覆盖率。无线传感器网络的定位精度基本能够满足应用的需求。

Based on the IAPIT wireless sensor network localization algorithm research

the application of wireless sensor network fields covers the military, health care, environmental protection and transportation, test because it involves a size, power and cost some factors limit, popular now global positioning system and wireless sensor network node location is not complete. So, this paper discusses the wireless sensor network with the localization algorithm has a wide application value and the very important theoretical value. This article deep research of wireless sensor network IAPIT location algorithm, this article is not the same node communication radius and anchor node proportion, the simulation IAPIT algorithm and APIT discussed the performance of the algorithm. From the experiment can see, APIT algorithm and IAPIT algorithm is, greatly increases the location coverage, a wireless sensor network positioning accuracy of basic can meet the needs of the application.
