观测微气候变化是无线传感器网络最热门的应用之一。然而，一些目标环境往往对人类或大型机器人来说过于危险或难以到达，并且在那些恶劣环境中部署和维护无线传感器网络面临诸多挑战。本文提出了一种移动传感器网络系统来解决这一问题。分别对系统架构、移动节点设计、基本行为和高级网络功能进行了研究。在此提出了一种基于轮子的机器人节点架构，它可以为无线传感器网络增加可控的移动性。还创建了一个包含一些原型节点的测试平台，用于验证所提出的移动传感器网络系统的基本功能。进行了运动性能测试以获取移动节点的定位误差和功耗模型。自主部署实验的结果表明，移动节点能够均匀地分布在先前未知的环境中。它为网络部署和维护提供了有力支持，并能确保传感器网络在恶劣环境中正常工作。
Observing microclimate changes is one of the most popular applications of wireless sensor networks. However, some target environments are often too dangerous or inaccessible to humans or large robots and there are many challenges for deploying and maintaining wireless sensor networks in those unfriendly environments. This paper presents a mobile sensor network system for solving this problem. The system architecture, the mobile node design, the basic behaviors and advanced network capabilities have been investigated respectively. A wheel-based robotic node architecture is proposed here that can add controlled mobility to wireless sensor networks. A testbed including some prototype nodes has also been created for validating the basic functions of the proposed mobile sensor network system. Motion performance tests have been done to get the positioning errors and power consumption model of the mobile nodes. Results of the autonomous deployment experiment show that the mobile nodes can be distributed evenly into the previously unknown environments. It provides powerful support for network deployment and maintenance and can ensure that the sensor network will work properly in unfriendly environments.
