Security study in wimax mesh networks

Abstract

WiMax Mesh mode allows direct communication between Subscriber Stations (SS) without the need of the Base Station (BS), thus improved network coverage. In Multi hop wireless systems such as WiMax Mesh Networks, security emerges as a vital requirement from the threats of both Malicious Sponsor Node (SN) and Candidate Node (CN). Network Entry Process (NEP) is applied for CN to join an active Mesh Network for authentication and registration.

Most studies have shown that NEP is vulnerable to different type of attack and proposed a better scheme to withstand the respective attack. However, not many papers focus on the Topological Attacks such as Wormhole and Sinkhole which could introduce problems to the routing protocols.
