Recently lot of interest has gained in ad hoc networks which are characterized as networks without any fixed topology due to high mobility. In ad hoc networks due to high mobility and lack of fixed infrastructure network disconnections occur frequently. Hence data accessibility in ad hoc networks is lower than in the fixed infrastructure networks. In this paper, the authors address cooperative caching mechanism to improve data accessibility in adhoc networks. Proposed solution is based on the size of the cache in nodes. For large-sized caches, nodes take decision independent of each other whether to cache some data and how long.
