Research And Implementation Of Ad Hoc Network Based On Bluetooth

Ad Hoc network is constituted by a mobile node equipped with a radio communication apparatus,a temporary,dynamic formation of a multi-hop network.As Ad Hoc network node moving freely,network topology changes at any time,so traditional routing protocols used in the Internet is no longer applicable to the Ad Hoc network.In addition,because the mobile nodes have lower computing power,storage capacity and energy are relatively limited,the design of the routing protocol must be simple and efficient.Researchers design a range of routing protocols for Ad Hoc Networks,therefore,researching and realization of these routing protocols have become an important content of the Ad Hoc network research.This article combines Ad Hoc routing protocols and mobile phone Bluetooth wireless communication technology,uses the Android system mobile phone design and realizes Bluetooth Ad Hoc network phone instant messaging system,user-friendly mobile phone Bluetooth multi-hop communication,so as to achieve the purpose of the extension of the Bluetooth communication distance.Firs this article researches several common routing protocols in Ad Hoc Networks,and give them the appropriate comparison.In this paper uses OLSR agreement to achieve multi-hop communication system,and designs the component structure of the system and various functional modules,focus on describing OLSR protocol routing module;then introduce a system to achieve;Finally,testes the system and analysis of results,and puts forward the next work.Mobile phone Bluetooth multi-hop network communication which is based on Bluetooth Ad Hoc network mobile phone instant messaging system,a typical application of the Ad Hoc network technology in the field of instant messaging,the Ad Hoc network technology,the Bluetooth wireless communication technology and instant communication the combination of strong practical value.
