The Design And Implementation On Routing Scheme Of Micro-Power Wireless Communication

In the smart meter data collection system,the Micro-Power communication protocol is used in wireless communication module.Wireless meter reading can greatly reduce operation costs and avoid artificial metering errors.The MPPR routing is a kind of static table routing,which is complex to generate routing,difficulty to update routing information,extend networks scale and need so much flash storage space.In the entire life cycle of the networks,the routing will not be changed after the routing has been generated.Firstly,Routing report scheme has been optimized,control overhead has been decreased,simplified networks building process,satisfied the hardware requirement of node's storage space and adapted to complexity scenario in CMPPR routing scheme.CMPPR scheme has been designed based on CEBR algorithm for Micro-Power wireless organized-self reading meters.Then,this thesis analyzed time delay,routing control overhead and space and time complexity among the different routing schemes in theory.On OPNET simulation plat,simulate several kinds of routing scheme.Finally,software communication protocol stack has been achieved on ARM plat and run a networks experiment to verify that the scheme is available and effective.In CMPPR scheme,70% storage space has been decreased and time complexity has been pulled down to 2 power from 4 power.60% routing generation control overhead has been reduced in 150 nodes networks.The hardware networks testified that CMPPR scheme could build the self-organized networks,simplified the routing generation process,effectively updated routing information and enhanced scale expandability.The application reading data time delay increased 57%,but could satisfy the application requirement of reading a meter data within limit of 5 seconds.This thesis designed a kind of available and effective self-organized networks building and routing scheme from the perspective of engineering for Micro-Power wireless smart meter data reading scenario.And CMPPR scheme will be a candidate to be deploy in a networks.
