Routing and Tolerant Security Framework Architecture for Routing Services in WANET

Abstract

Wireless Ad hoc Network is a network where there is no existence of wireless infrastructure for networking. Threats to network resources increase exponentially with the growth of the network/users and with technological developments. Due to the raising dependence of people on critical applications and wireless networks, high level of reliability, security and availability is claimed to assure secure and reliable service operation.. In this paper, the authors describe a security  management Architecture for access control to network resources. In order to support both network operations and security requirements of critical applications, we present SAMNAR, a Survivable Ad hoc and Mesh Network ARchitecture. We identify the new challenges and opportunities posed by this new networking environment and explore new approaches for  secure communication .Our proposed goal is managing adaptively preventive, reactive and tolerant security mechanisms to provide essential services even under attacks, intrusions or failures. We use SAMNAR to design a path selection scheme for WANET routing. The evaluation of this path selection scheme considers scenarios using urban mesh network mobility with urban propagation models, and also random way point mobility with two-ray ground propagation models. Results show the survivability achieved on routing service under different conditions and attacks.
