Wireless Sensor Networks (WSNs) consists of large number of low cost devices that are deployed in the region of interest. WSNs communicate over a wireless medium and collaborate to accomplish a common task e.g. habitat monitoring, hazard monitoring, battlefield surveillance. Sink that is located close or inside the sensing region, sends the queries to Sensor Nodes (SNs). SNs collaboratively sense the desired data sends it to the sink. Cooperative caching can play a major role in handling the request effectively. This helps WSNs in alleviating the situations of non availability of data, and reduces the requirement of wireless bandwidth, storage and energy, by deciding for the particular data item, whether it should or should not be cached.
