Evaluating Secure Cluster Formation in Personal Networks

In this paper we evaluate our previously proposed security architecture for personal networks (PNs). Personal network is a new concept utilizing pervasive and distributed computing to meet the needs of the user. We aim to secure personal networks with lightweight security mechanisms that are suitable for resource constrained devices yet robust enough for self organization and secure communication. In order to study the behavior of our proposed security mechanisms we developed a simulation environment in NS-2. The simulations are used to evaluate the overhead of our mechanisms and to understand the effects of key parameters. The results show that our mechanisms have low delay and energy requirements and are feasible for the heterogeneous devices we envision in our PN.
