Mobile Ad Hoc Secure Routing Protocol Based on Trust Preserving

Moving characteristic is a important factor in secure routing for Ad Hoc networks.Most secure routing protocols are difficult to finish the authenticating processing and can′t set up the secure routing in a mutative and high speed moving network because authenticating is a continuous processing for messages exchanging and the moving characteristic can′t ensure the continuity.This paper proposes the trust preserving based secure routing protocol based on OLSR,the trust preserving method is adopted to accomplish the authenticating and resolve the high speed moving authenticating problem,which is proved with the formal language.Aiming at the low flexibility of most trust evaluating system,a novely evaluating system is proposed,by which the nodes get the trust information,identify and limit the vicious nodes,at the same time,it can resist the associated attacks,such as worm-hole attack.The simulations shows that in a high speed moving network,The TPSRP′s authenticating performance is more better than that of the traditional and can isolate the attacking nodes effectively.
