Based On Subjective Logic Of Security And Credibility Of Manet Routing Protocols

Mobile Ad hoc Network is a peer-to-peer network with special usage, which is without infrastructure, self-organizing, dynamical reconfiguration and mobile, and so on. Wireless Mobile Ad hoc Network have a lot of particularity,it is because that the security is bottleneck of Wireless Mobile Ad hoc Network development, and the security of route protocols are the most important. The most route protocols in Wireless Mobile Ad hoc Network will build the route, the wireless node will exchange the topology information. It makes the route protocols become the aim of the malicious nodes attacking.This paper introduces the foundational conception, phylogeny, applies field, particularity and security problems of Wireless Mobile Ad hoc Network, and analyses its system structure and every layers studying point. This paper mostly study the route protocols of Wireless Mobile Ad hoc Network and it security problems,mostly introduce the AODV route protocol, and analyses its operation of route finding, route maintain, route repairing, route backout. Basing of AODV, the security and trusting route protocol which name STRP_AODV is proposed.This paper proposes security and trusted route protocol model based on subjective logic. It is based on analyzing and concluding the security of Wireless Mobile Ad hoc Network and the state-of-the-research of security route protocol. This model is on the basis of AODV route protocol. Through node authentication for each other and action information, positive and negative information is concluded. Opinion among notes is calculated using of forward combination and consistent combination. This paper improves on algorithms of Opinion and introduces time and negative event effective. This improvement reflects actual information of network more accurately. The principle of AODV route protocol is deeply and detailed analyzed, and achieved the major part of model on the basis of AODV route protocol.Finally, Using of NS2 emulator,build the Ad hoc Network scene in different nodes, and emulate AODV route protocol and STRP_AODV route protocol, thought the data analyses, an secure and trusted route is found in little cost.
