传感器网络下目标追踪实验设计

An Experimental Design of Target Tracking in Sensor Networks

文中设计了一种无线传感器网络下的移动目标追踪实验,介绍如何在模拟器上实现网络节点部署、组织和追踪移动目标。实验中移动物体依据真实出租车轨迹、高斯马尔科夫模型或随机路点模型进行移动;网络中节点则依照粒子滤波算法进行目标追踪和数据采集。该实验作为《无线传感器网络》课程的配套实验,有利于学生更好地理解基础理论知识,并且能锻炼学生在无线传感器网络模拟器上的实际编程能力。

This paper designs an experiment for mobile target tracking in wireless sensor networks,in which the details of deploying and organizing sensor nodes on simulator,and algorithms of tracking moving objects are presented. In this experiment,target trajectory is produced by a real taxi trace,Gaussian-Markov model or random waypoint mobility model. Moreover,sensor nodes are organized as clusters to capture target,while utilizing particle filtering as the tracking algorithm. As a supporting experiment for wireless sensor networks course,this work can help students further understand the theoretical knowledge,and more importantly,enhance their ability of actual programming on wireless sensor networks simulator.
