Intra-Cluster Topology Creation in Wireless Sensor Networks

Clustering is proven method for energy efficient topology generation. However, in cluster formation high focus is given on cluster head selection while intra-cluster topology generation is not given much attention. In this paper, we have proposed intra-cluster topology-generation method for heterogeneous wireless sensor network (WSN). For cluster formation, we have used Voronoi tessellation with fix number of cluster heads. We have used leveling method to position the cluster nodes in the network to generate level based intra- cluster topology and exploited the property of variable transmission power of cluster nodes and cluster head.
