Energy efficient design of mobile wireless sensor networks: Constrained clustering

Abstract

The performance in Wireless sensor network (WSN) is improved by endorsing mobility e.g. reduces traffic by avoiding un necessary and less transmission and reception of packets, while less attention has been focused on selection of cluster head. Thus in this existing paper we design an energy efficient hierarchical routing protocol, we formulate cluster head choosing problem by considering both distance and energy as a quadratic optimization problem and provide a solution to it. To the best of our knowledge, the derivation of centroid of patterns based on interesting optimization problem is novel and is not known in the literature. We derive the position of centroid by formulating and solving an optimization problem by allowing mobility to sensors and base station/sink.
