Abstract
In this paper, we propose a cooperative caching scheme that exploits an energy efficient model in Wireless Sensor Network. Cooperative caching is done in the form of concentric circular cache layers around the sink. A Circular cache layer is a group of nodes falls under circumference of the circle formed from the sink as center with a certain radius. At a time only a single cache layer becomes active which caches the data in it. A fading-aware routing is utilized to minimize the total power consumption during packet transfer. The scheme performs well in the multiple sink environments. Proposed scheme is compared with the existing Fading-aware energy efficient routing approach. Simulation results show the performance and better efficiency of the network.
