粒子群APIS-3D算法在三维传感网络中的定位研究
RESEARCH ON LOCATION OF PSO AND APIS-3D ALGORITHM IN 3D WSN
摘要
Abstract
3D space location algorithms of wireless sensor networks are mostly to convert the 2D vector into 3D space,its principle is basically the same as plane location and is simple in implementation,but does not consider the impact of node mobility on location errors.This paper puts forward a new PSO and APIS-3D-based location algorithm,it uses particles to simulate node mobility status, sets up fitness function according to the dynamic feedback process of RSSI signal fingerprint, and calculates the coordinate of nodes by locating the centre of gravity of sphere intersection region.Simulation experimental results show that the new algorithm achieves the average location error less than 2.42% on mobile nodes under the condition of keeping the sampling probability unchanged,and can well meet the requirements of engineering applications.关键词
