Mobile Ad hoc Networks are wireless networks which are composed of mobile nodes without any kind of wired infrastructure. Dynamic topology is one of the crucial ingredients. There is a problem in accessing the data items because of Ad hoc Nature. Caching can help in mobile ad hoc networks to improve the accessibility and availability of data items. In this paper, we propose a novel caching scheme called Efficient Dynamic Group Caching (EDGC) which allows grouping of mobile hosts at one hop
