ZigBee Source Route Technology in Home Application

ZigBee is a new short-range wireless technology. ZigBee devices have parents and children relationship, and those devices can construct a huge mesh network. Most devices in ZigBee network can relay packets, repair route, etc. If a ZigBee device wants to send packets to another device, the source node needs to find a route to the destination. In an application, if data are sent to the concentrator form the sensing nodes and concentrator tends control the sensing nodes, the concentrator can record the path from sensing nodes to its self and send the data to the sensing node directly according to the recorded path. The relaying nodes using the receded nodes information relay packets. In this paper, we dealt about usage of the source route technology to find the best route and send packets directly according the recorded nodes information. In a huge mesh network, find a good route is very important. It can reduce the probability of packet collision and data loss. This technology is suitable in the application of user monitors the sensing area in the concentrator, .and send control packets to the sensing nodes from concentrator.
