Terminal's latency, connectivity, energy and memory are the main characteristics of today's mobile environments whose performance mayb e improved by caching. In this paper, we present an adaptive scheme for mobile Web data caching, which accounts for congestion of the wireless network and energylimit ation of mobile terminals. Our main design objective is to minimize the energycost of peer-to-peer communication among mobile terminals so as to allow for unexpensiveWeb access when a fixed access point is not available in the communication range of the mobile terminal. We propose a collaborative cache management strategyam ong mobile terminals interacting via an ad hoc network. We further provide evaluation of the proposed solution in terms of energy consumption on mobile devices.
