Wireless Mesh Networks (WMNs) have been expected to be the ultimate solution for the next decade wireless networking. The attractions of WMNs include easy set-up on the fly, off-the-shelf cost, flexible interoperability with other networks, and highly reliable connectivity. One main challenge in the design of these networks is their vulnerability to security attacks. The attacker will possibly be able to identify an ongoing communication session between any two network users by analyzing the network traffic pattern without knowing the users identity information. To address these security risks, Secured routing scheme that preserves the privacy of end users is proposed using Secured Identity Based Approach (SIBA) in which every nodes are assigned with the Security cards for efficient authentication. The major goal of the proposed system is to reduce the number of attacker level by providing anonymity in routing. This implementation results show that the proposed scheme can provide substantial performance increases and protects against performance degradation even in the presence of malicious behavior.
