Currently, it is widely used in such as industrial,medical,military areas,intelligent house, road monitoring ,home automation and soon. Typically,there are three kind of route algorithms,namely AODVjr algorithm ,Cluster-Tree algorithm and Cluster-Tree & AODVjr the three ones,the AODVjr algorithm isa short version of AODV protocol. We build a simulation platform of the work with the toolbox of TrueTime in Matlab,and then design the protocol of AODV on it. The design can be divided into several modules to achieve , they are the block of route discovery and maintance , initialization, the animation block, clock, node moving and sending and reciving introduce the route discovery and maintance block asa an improved AODV algorithm is analyzed in detail,which helps to reduce the loss of data and the probability work congestion. We simulate the real enviro n ment work by moving two nodes .As a result,we realize the feature of discoverying and maintaining a route, sending and receiving datas and soon. 【 Key words 】 ZigBee AODV Truetime Improved routing protocol 重庆邮电大学本科毕业设计(论文) - III- 目录前言.........................................................................................................
