An Activity Surveillance System for Building Based on Combining ZigBee and WiFi

ZigBee和WiFi各自具有明显的特点,并且许多特性具有互补性,将二者相结合具有很好的应用前景.提出了一种基于ZigBee技术和WiFi技术相结合的楼宇监测体系结构;研究了解决传感数据采集、坐标系统的建立、机器人的控制等关键技术的方法;实现了一种简单、易于实现、高效的基于能量均衡的分簇多跳路由算法,能够较好的提高传感器网络的生存期;实现了监测系统,并得到了实际应用.

ZigBee and WiFi have more obvious characteristics and these features are complementary each other. Combing ZigBee with WiFi has good prospect. This paper proposes an architecture of activity surveillance for building based on ZigBee tehnology and WiFi technology, finds out some ways to resolve some key technologies such as sensor data acquisition, the establishment of coordinate systems and robot control. It also proposes and implements a simple, easy to implement and efficient algorithm （the sub-cluster multi-hop routing algorithm based on energy balance）. This algorithm can improve the existing sensor network. This activity surveillance system has been implemented and applied into practical application.
