Pseudonym Based Security Architecture for Wireless Mesh Network
Ms. Sharvani R. Marathe, Santosh L. Deshpande · IOSR Journal of Computer Engineering · 2014
Wireless Mesh Network (WMN) is a wireless network with mesh topology and is expected to be widespread due to the advantages such as low deployment cost, easy maintenance, robustness, scalability, reliable service coverage and high performance.It has self-configuring and self-healing ability and is compatible, interoperable with existing wireless networks.With these advantages, WMN inherits security issues that need to be considered before the deployment and proliferation of the network, as it is unappealing to subscribers to obtain services without security and privacy.It is difficult to achieve both, privacy and security together in a system but an attempt is made by designing a ticket-based security architecture achieving anonymity and traceability in WMN.Anonymity provides protection to the users to access network services without being traced i.e. preserving the identity of the user and has been extensively studied in payment-based systems such as e-cash and peer-to-peer systems.When anonymity is achieved, few entities tend to misbehave by imposing attacks as they remain anonymous.This affects network security and hence, misbehaving entities have to be traced.The clustering concept is included in the system to increase network performance and to reduce topology updating overhead in the network.
