Abstract: An application specific Wireless Sensor Network (WSN) is a combination of few to large number of sensor nodes deployed in certain geographical region along with a sink node either within or outside that region of deployment. The sole objective of the sensor nodes is to collect the desired data from the environment and transmit that to the nearby sink node for further information extraction and forwarding to the subscriber’s location periodically. However, the periodic updating might be irrelevant for the subscribers. In this process there is unnecessary wastage of battery power of the sensors as well as degradation of the performance of the sink node. In our proposed content centric framework we have addressed the issue by considering the Cluster Head (CH) nodes among a group of nodes, processing the received data from the sensors and forward the information to the sink node based on the desired attributes of the subscribers. The filtration mechanism not only reduces the wastage of the battery power but also enhances the network life time as well as the bandwidth utilization in the network. From the simulation it has been observed that our CCN outperforms the traditional based periodic communication model.
