Energy-efficient routing for 2D grid wireless sensor networks

Wireless sensor networks have become possible because of the on-going improvements in smart sensor technology. One important issue in wireless sensor networks is to achieve energy-efficient operation in order to extend network lifetime. For many applications, placement of sensing nodes can be pre-determined. In this paper, we propose several power-efficient routing algorithms for a sensor network with 2D grid topology, demonstrating that optimal routings are operation-specific and energy consumption can be minimized by optimally selecting data paths and base station location.
