The paper presents a performance evaluation of Scale-net, a relatively newer logical topology that was introduced by the authors in their earlier work [1]. The proposed irregular topology is based on de Bruijn graph, a regular, non-scalable one with simple routing strategy. The Scale net could consist of any arbitrary number of nodes. In spite of being a irregular topology, it follows a simple, yet efficient routing logic. Also, perturbation is relatively low in Scale-net when the network grows in size. The simulation results confirm the theoretical prediction of a small diameter and low average hopping distance.
