Grid-Based for Energy Conservation around Obstacles in Wireless Sensor Networks

Reducing energy consumption has been a recent focus of wireless sensor network research. Topology control explores the potential that a dense network has for energy savings. We propose that the sensor field be overlaid with a honeycomb virtual mesh based on a tessellation. Then with the help of greedy forwarding algorithm and perimeter forwarding algorithm, we can bypass a void or obstacles easily. And we can save energy to prolong the life time of the wireless sensor networks.
