摘要：

In this paper, a chain-based data gathering scheme for grid-based (CDGGB) Wireless Sensor Networks (WSNs) is presented. The whole sensor area is divided into several logical network grids. Each grid has a head node responsible for transmitting aggregated data. In order to reduce energy consumption, we link each head node to build a chain. The head node which is nearest to the BS makes itself as a leader that takes charge of transmitting aggregated data to the BS. The head node which is at the farthest distance of the BS makes itself as one chain end and its downlink head node as the other end. Subsequently, both end head nodes respectively transmit their own aggregated data to the chain leader in the opposite direction. The results of simulations reveal that the proposed CDGGB increases the efficiency of energy-using and prolongs the lifetime of the whole network. © 2015 by Binary Information Press.
