Delineate a Technique to Maintain Consistency in Cache Based Wireless Sensor Network

Ritika Mehra | Er. Harnek Singh

Abstract: Wireless Sensor network have many different properties unlike other wireless networks. WSNs are highly distributed networks where cooperative caching can act as an important feature in handling the communication effectively making WSN to use its energy efficiently. WSN is collection of large number of sensing nodes that sense the environment they are deployed in and after sensing, computation, transmit the data over the transmission channel comprising of sensor network and sink node. In this paper we present a technique called push based technique for caching data in wireless sensor network. The sink node uses a cache discovery algorithm to find the node who has cached the data item that the sink needs to access. It also employs cache consistency, cache replacement algorithm that improves the overall performance of the system. Simulation experiments show the better results as compared to the other caching techniques.
