Efficient Data Gathering With Mobile Collectors and Space-Division Multiple Access Technique in Wireless Sensor Networks

To maximize network coverage and to provide a reliable, energy-efficient monitoring depends on selecting minimum number of sensors in active mode to cover all the targets. This power saving technique can be regarded as Set Covering Problem (SCP). Designing for a minimum set of nodes where node selection procedure is based on the energy of each node in a set, provide energy-efficient sensor network. The performance analysis through simulation results show that the algorithm proposed in this paper selects less working nodes than the other algorithms and maximize the network lifetime as well.
