A ZigBee Based Mesh Network for Home Control System

The current development and the application status of the home network are introduced briefly, then, a two-tier architecture of home control system (HCS) based on ZigBee multi-hop mesh network is presented. In addition to the basic data acquisition and processing functions, the gateway which has been designed and fabricated supports ZigBee based wireless access interface, Bluetooth based local interface and GPRS based remote interface. The hardware architecture and protocol software, as well as the communication control method are proposed in detail. Under the constructed test environment, the performance results show that the proposed scheme is more convenient for home control services, and except the gateway, all of the router nodes in the system work on sleep mode at most of the time, which will improve the lifetime of the whole system efficiently.
