The Application Design Of Wireless Mesh Routing Protocol In The Village Access Control System

As an emerging information technology,the Internet of Things is a network technology which based on fully using of the Internet or a local network.In order to achieve remote management and control of information with information technology and intelligence,It linked data servers,operation and maintenance servers,sensors,controllers,associated people or items together.As a special ad hoc network, wireless Mesh Network(WMN referred WMN) is a P2 P network technology.Wireless mesh network is a network structure which is synthesis of the radio communication technology and IP technology,which having the characteristics of muti-hop,dynamically building a route,varied network topology,multiple networks coexist,and automatic identification of different forms of network.It has a higher network capacity, faster transfer rates, greater robustness, and better scalability and lower cost and so on.The main content of this article is design a IOT-based Murai access system using different networking, for the demand of the national intelligence township project in Guangdong Province, Firstly, to study the actual needs of the project that is the management of the floating population.Then, analyzing the actual traffic demand of the Murai access control system project which is on the framework of the Internet of Things.Combined with the environmental factors,the scene is divided into single-hop and multi-hop scene.In the choice of networking solutions,we firstly analyzed the three network structure, unified international standards and related technologies of a wireless mesh network.Secondly,Combined with the actual traffic projects,we analyzed the problem of using Proactive routing protocol, reactive routing protocol directly in the actual scene and the Simulation of the three major parameters of communication,which are overhead,end to end delay and delivery rates. Thirdly,Analyzing the bringing problems and deficiencies when we use the hybrid routing protocols which having the advantages of the both routing protocols,from this,we propose a practical and improved networking scheme which is more suitable for our System.NHM,which have two parts,based of tree and based on demand is our new routing protocols,we designed the two parts of it,the selections of routing criteria and so on.Then,Designed and implemented the Murai access control system according to the actual scene of division.We designed and implemented Single-hop Murai access control system for single-hop scene;We designed the Multi-hop Murai access control system using a modular approach for multi-hop.We also analyzed the simulation of the improved multi-hop networking solutions.
