A Research On Positioning Communication Algorithm

With the development of high technology, various aspects which from personal life to thebig companies, or the field of military have begun to intelligentize. Intelligent transportationhigh-tech era is coming quietly. In this paper, we design a close high-precision positioningauxiliary system, combined wireless sensor network positioning technology and Ad Hocnetwork communication technologywith the positioning communication algorithm to networkcommunication. Implement an efficient real-time communication around the cars.The mainresearch content of this paper is as follows:First, this paper introduces the wireless network communication technology developmentand research status at home and abroad, analysizes the wireless sensor network (WSN)technology which is based on range-based and range-free technology localization algorithmand the fixed coordinate calculation method, discusses the principle and system structure ofAd hoc network communication technology and the commonly used communication routingprotocol.Compares the advantages and disadvantages of the commonly used protocols,thenintroduces the applied occasion.Second, analyze the overall function and structure of close cars location communicationsystem in detail. combined with the range-based positioning technology design a close carsfixed positioning communication system. Implements the positioning communication forclose cars in real-time. Study the positioning process, and coordinate correction process.Third, presents a positioning communication initialization algorithm and dynamicupdating algorithm, details the principle and process of the algorithm. After positioningcommunication initialization algorithm was executed, The whole system enter into the staticstate of Ad Hoc network communication, Then combining with the dynamic updatealgorithm, complete the establish of an Ad Hoc networks for dynamic cars real-timepositioning communication. finally, This paper makes simple analysis on the performance ofthe algorithm，and points out the theoretical error are in centimeter, discusses the feasibilityand the accuracy of the algorithm through the experiment, meet the demand of the precisionof the new system.
