Self-Healing Network Design Based on Zigbee

ZigBee technology is a low-power wireless communication technology.It is a self-organizing network.Network capacity is large and the transmission rate is appropriate.In order to achieve self-healing network improved address allocation algorithm and tree routing algorithm.When routing node dead,the algorithm could achieve network self-healing.Algorithm did not have to re-allocate network addresses and rebuild the network.Algorithm can improve the network lifetime and solve the problem about no address node.Analyze the algorithm using simulation software of OPNET.Prove the feasibility of the algorithm.
