short-distance wireless

ZigBee, a low-cost, low-power consumption, short-distance wireless communication technology, is designed for the low-rate wireless sensor network and control network, so this technology can be used in the application fields of wireless communication such as the wedding gowns dresses industry control, house automatization and medical treatment and so on. Because the ZigBee device is supplied energy by batteries and the energy of the batteries is limited, the lifetime of the ZigBee network is based on the batteries seriously. Therefore, it is important to use the energy of the new shoes 2010 batteries efficiently in the Zigbee network, and the research of the routing new wedding dresses algorithm based on energy efficient for ZigBee network is very significant.In this thesis, first, I introduced the cheap evening dresses features and some conceptions of the ZigBee network. Then, I gave a detiled introduction to ZigBee tree routing algorithm and AODVjr algorithm, proved some formulations and analyzed the shortcomings of the existing research work. Based on these, I proposed the improved discount wedding gowns ZigBee tree routing algorithm based on energy-balanced and ZigBee AODVjr algorithm based on control -overhead reduced in the interest of saving the network's energy and prolonging its lifetime.Aiming at the problems of ZigBee tree routing algorithm that the routing may be not optimal and some nodes may use up all the energy because of heavy transmissions, an improved ZigBee tree routing algorithm based on energy-balanced was proposed.
