Popular content stored within the Internet may be costly to download via modern 3G connections due to a fee charged by telecommunication providers on the basis of the amount of data transferred. This work presents a network in which several mobile devices, called peers, cooperate to download their assigned portion of the content using a 3G connection in order to reduce the overall cost to download the content. Then, the peers exchange their assigned portion of the content with other peers via a wireless ad hoc network and the peers reconstruct the content. Each peer is associated with a server located within the Internet. The associated servers cooperate to schedule each peer to download its unique portion of the content. In addition, the servers schedule the distribution pattern for exchanging content between the peers. The results indicate that approximately 90% of the telecommunication cost is saved with as few as 10 peers.
