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...
Topology control for fault tolerant communication is one of the important issues in wireless sensor networks. This paper presents a simple mechanism of fault tolerant topology control for generating undirected scale-free networks, where the network evolution is determined by the rules of growth and preferential attachment. The authors prove that this mechanism produces scale-free networks with degree...
