Modeling the Topology for Cluster-Based Wireless Sensor Networks

In this paper, we model a novel topology for cluster-based wireless sensor networks (MforW). Numerical simulations indicate that MforW has scale-free properties. Scale-free networks are inherently robust and efficient. By using the concept of network efficiency, we investigate the effect of attacks on the network. We find that MforW provides fault tolerance and avoids the effect of cluster head failures by constructing multi-path and multi-hop routing from cluster heads to the cluster heads and on to the base station. Simulation results also show that MforW outperforms LEACH, BCDCP and LEFC in terms of energy dissipation.
