Because of the limited energies of sensors, efficient data gathering in wireless sensor network has been received a great deal of attention recently. To prolong the network lifetime, in this paper, we study the problem of scheduling a mobile sink to some specific nodes, termed anchor nodes in this paper, for data collection and reducing the energy consumption of data transmission. While considering...
Data aggregation in wireless sensor networks eliminates data redundancy, thereby improving bandwidth usage and energy utilization. This paper presents a data aggregation algorithm, called MRDWA (Multi-Role Dynamic Weighting Aggregation), it mainly used in event driven WSN (Wireless Sensor Networks). MRDWA is based on cluster topology structure, and use different data aggregation algorithm according...
