【摘要】 目标跟踪是无线传感器网络的一项基本应用,而低能量消耗和高跟踪精度是设计目标跟踪算法或协议的主要目标。本文提出一种基于邻域协作的目标跟踪算法来满足此要求。本文首先讨论了感应节点在邻域空间的权重,然后提出一种基于节点权重的加权质心算法来估算目标的位置,通过节点之间的相互协作来确定目标的运动轨迹。模拟结果表明本文所提出的算法在能量消耗和跟踪精度两个方面具有良好的效果。更多还原

【Abstract】 Target tracking is a foundational application in wireless sensor networks,low energy consumption and high tracking accuracy is the main goal for target tracking algorithms or protocols.This paper proposes a target tracking algorithm based on neighborhood collaboration(TNC) to meet this requirement.This paper first discusses the node weight for each sensing node in its neighborhood space.Then,it proposes a weighted centroid algorithm based on the node weight to estimate the location of the target,and determine the trajectory of the target through cooperation between nodes.The simulation results show that the proposed TNC algorithm has a good performance in energy consumption and tracking accuracy.更多还原
