Credible Routing Protocol Based On The Zone Dynamic Trust Management

Mobile Ad hoc Networks is a kind of new wireless communications network, has attracted people's widespread attention. But at the same time it is a complex network, involving a wide range of research content. As a new type of network, there are many inadequate, and new applications for its research and development are constantly new challenges. Currently, there are many practical problems for Mobile Ad hoc Networks to be solved. But be sure that with further research, mobile Ad hoc networks will play its unique, more influential role in the wireless communications.This paper discussed the differences of the mobile Ad hoc networks and traditional wireless network, analyzed the characteristics of the mobile Ad hoc networks and security issues, researched and analyzed the current routing protocols. Comprehensively considered the development goals and situation of safe reliable routing protocol, and on account of many Ad hoc networks'security threats, this article put forward a new mobile Ad hoc networks security credible routing protocol. This protocol adopted the recommended based on local distributed trust model as a whole and with efficient ZRP routing protocol as the foundation, combined with dynamic adjustment, zone updates, authentication only when necessary and other strategies, which can effectively prevent path information tampering and routing node failure, and other malicious attacks and improve the network routing information of credibility, a better solution to the ad hoc network routing on a routing information in disguise, tampering, and other security issues. Based on the local recommended agreement distributed trust model, we could reduce the cost of network resources, and had relatively simple algorithm, and had the assurance of iterations, it adopted the ZRP routing protocol, could be able to resolve routing loops and long convergence time.This paper described the theoretical basis and technical principles of the credible routing protocol based on the zone dynamic trust management, and the process of route discovery and route maintenance. Finally, by the performance analysis of this proposed routing protocol, and the comparison with other same type protocols, we could find that this protocol had better efficiency and safety.
