Research On Zigbee Routing Algorithm And Its Application In The Data Acquisition System

As the wireless sensor nodes need to be distributed in the external environment for data collection,usually using the battery for power supply,it must reduce the energy consumption of the node.ZigBee technology become the most widely used wireless sensor network communication technology,its low power consumption,low data rate and low cost.And by design and implementation of ZigBee-based wireless sensor network data acquisition system,to understand the ZigBee protocol architecture,and study of AODVjr routing algorithm,Cluster-Tree routing algorithm,ZigBee routing algorithm.The specific research contents are as follows:(1)Introduce the architecture of ZigBee protocol,analyze the node device type and ZigBee network topology in ZigBee network,establish the routing strategy of ZigBee network,and prepare the routing algorithm in ZigBee technology.(2)By studying the formation process of ZigBee network,and the AODVjr routing algorithm and Cluster-Tree routing algorithm,and then combined with the advantages of selecting the best path in the AODVjr routing algorithm and the convenience of forwarding the packet through the parent-child node ZigBee routing algorithm.Finally,the ZigBee routing algorithm is used to reduce the end-to-end delay in the ZigBee network to a certain extent,and to improve the correctness and effectiveness of the ZigBee routing software through the NS-2 simulation software.(3)Determine the environmental parameters to be collected in the area to be measured,design the ZigBee terminal node,ZigBee routing node and ZigBee coordinator node in the ZigBee network,and write the environmental data in the host computer.Real-time display software ZigBee wireless sensor network acquisition To the temperature,humidity,light intensity information to store and to parameters and curves in two forms to show to the technical staff.
