It may be costly for mobile pervasive computing device users to download content from the Internet using their 3G connections if the 3G connection cost is a function of the amount of data downloaded. This paper introduces an approach in which mobile pervasive computing devices form an ad hoc network and share downloaded content with each other. In order to improve privacy when sharing content, this paper describes an anonymous connection between the sending peer and the receiving peer. Simulation results show that the transmission overhead of the anonymous connection may increase 50% or less as the number of peers increase or the peers are scattered over the larger area.
