Abstract


Energy efficiency is a very important issue in wireless sensor networks (WSNs). Sensor nodes are battery-powered, thus the energy of them is limited. Data transmission is energy-intensive for sensor nodes, particularly over long distance. In this paper, an efficient Grid-Based Data Aggregation Scheme (GBDAS) for WSNs is proposed. In GBDAS, the grid structure is constructed by dividing the sensor network into a grid of cells, so that most of sensor nodes merely transmit the sensed data within the local cell. Only a small part of them need disseminate data towards the BS, greatly decreasing the energy load of sensor nodes. Besides, the position of each dissemination node is selected in rotation so that the energy depletion of sensor nodes is equally distributed. Consequently, the lifetime of network is extended.
