Wireless sensor networks have the ability to monitor the physical environment and mainly network used in military and civilians applications. The sensor node has limited energy and there is a key challenge to reduce the energy consumption in the network. The huge amount of data generated in the network to manage the data in the network the authors propose an index based cooperative caching scheme. These techniques reduce the communication cost for transmitting data and efficiently process the data queries. Index node stores the location of caching nodes so queries are not routed in the whole network.
