远程环境监测是无线传感器网络技术的重要应用之一，它利用分布在空间上的传感器节点来监测环境参数，并通过网络协同传输数据。本文讨论了一种混合无线传感器网络中多机器人平台的设计，以监测环境变化。该系统包括一组静态无线传感器节点、一组移动机器人和一个中央控制器。移动机器人有助于缓解交通拥堵，促进近距离监控能力。为了机器人的有效导航，该系统使用了已知的环境地图、传感器读数和来自无线传感器网络的导航。多种导航技术的结合大大减少了移动机器人路径规划的误差。网络中的传感节点将积累的数据转发给中央控制器进行分析。中央控制器将根据不同的阈值级别对数据进行分类并记录数据。如果系统检测到超过当前阈值水平的事件，则会向系统的授权用户发出预警。
Remote environmental monitoring is one of the important applications of wireless sensor networking technology where spatially distributed sensor nodes are used to monitor environmental parameters and collaboratively transmit their data through the network. This paper discusses the design of a multi robotic platform within a hybrid wireless sensor network to monitor the environmental changes. The system includes a set of static wireless sensor nodes, a set of mobile robots and a central controller. Mobile robots help to reduce traffic congestions and facilitate close monitoring capabilities. For the effective navigation of the robot, the system uses a known map of the environment, sensor readings and the guidance from the wireless sensor network. The combination of more than one technique for navigation significantly reduces the errors in path planning of the mobile robots. The sensing nodes in the network will forward the accumulated data to the central controller for analysis. The central controller will classify the data based on different threshold levels and records the data. If the system detects an event which exceeds current threshold level, then it will provide an early warning to the authorized users of the system.
