Geographically Inspired Virtual Grid for Wireless Sensor Networks

Topology management is a critical issue in the context of wireless sensor networks. There are different factors by which topology of a network may be affected. Maintaining this topology in uncontrolled mobility of nodes and make it to work efficiently is a tedious task. In this paper, we propose an efficient topology management strategy based upon geographical forwarding information. Simulation experimentation reveals that geographically inspired virtual grid [GIVG] achieves significant improvements compared to other approaches in terms of energy consumption and communication overheads.
