Optimal Routing Service for Wireless Network security and Management

WirelessNetwork Environment poses its unique challenges to the existing Transaction models which are fail to solve. Wireless ad hoc networks (WANETs) experience serious security issues even when solutions employ preventive or reactive security mechanisms. In order to support both network operations and security requirements of critical applications, we present SANA, a Secure Ad hoc Network Architecture. Its goal lies in managing adaptively preventive, reactive and tolerant security mechanisms to provide essential services even under attacks, intrusions or failures. We use SANA 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. Keywords— Mesh Network, Security management, wireless ad hoc networks, survivability, routing.
