A Performance Evaluation of a Novel Clustering Scheme Considering Local Node Density over WSN
نویسندگان
چکیده
This paper is an extension of previously proposed a novel clustering scheme, called D-LEACH, that is based on the calculation of local node density to increase the WSN lifetime by efficiently reducing energy consumption at the sensor node. In this paper, we present both mathematical analysis and performance evaluations of our proposed D-LEACH in view of energy consumption of network. By computer simulation, we showed the ratio of preclustering executions, which is an additional stage to existing LEACH, to total rounds over whole network lifetime. Also, we investigate the progress of live nodes according to changes in local node density, and the progress of active nodes considering local node density in D-LEACH.
