Research Of Routing Protocol Based On ZigBee For Measure And Control System In Grain Storage

The paper do the research of the ZigBee routing protocol and constructes the the new energy- efficient route protocol of ZigBee based on the wireless grain measure and control system.The paper discussed according to the following sections:The first part of this paper gives an over view of the research on wireless sensor networks,including the system configuration, stack architecture, character of routing protocols of the wireless sensor networks. Then the development,stack architecture,technical characters and the application of ZigBee are introduced. In the second part,based on the analysis of network configure,network topology, network formation and network address assignment mechanism of ZigBee, the routing protocols of ZigBee are analyzed deeply.The idea and the operation process of ZigBee routing are introduced in detail. After that, the performance of ZigBee routing is evaluated. Based on the module of IEEE 802.15.4 MAC layer and the module of IEEE 802.15.4 physical layer, the code of the network layer of the network layer of ZigBee is developed and debugged, and the network formation, the network address assignment mechanism of the routing protocols of ZigBee network are realized. The performances of ZigBee routing are analyzed deeply through the simulation.The result of the simulationin dicates that the delivery rate,the end-to-end delay and the controlover head of ZigBee network can meet the system requirement well.The energy efficiency strategies of ZigBee routing are given in the third part of this paper. Its idea should be selected when there residual energy of all nodes of ZigBee network are enough, and the protocol should avoid selecting the nodes with lower energy when the energy of the node in the network is insuficiency. The aim of these strategies are balancing energy consuming of the network, and extending the life of the network. The result of simulation indicates that the conditional balanced energy consuming ZigBee routing postpones the network partition and extends the life of the network without sacrificing the other performance.
