Energy efficiency is a critical factor for operation of a wireless sensor network. In general, wireless sensor networks perform clustering and routing using localized neighbor information and simple rules only. In this paper, we propose an energy efficient clustering and routing method for wireless sensor networks by exploiting energy state information of(More)
Energy minimization is a central issue for wireless sensor networks (WSNs). We propose an energy minimization model and suggest a solution algorithm for multi-hop flat routing for WSN. This model is based on some directed minimum spanning trees and the related tree packing problem. We compare this model and some known optimization model and algorithms for(More)
