Popular content stored within the Internet may be costlyto download via modern 3G connections due to a feecharged by telecommunication providers on the basis of theamount of data transferred. This paper presents a networkin which several mobile devices, called peers, cooperateto download their assigned portion of the content using a3G connection in order to reduce the overall cost to downloadthe content. Then, the peers exchange their assignedportion of the content with other peers via a wireless adhoc network and the peers reconstruct the content. Eachpeer is associated with a server located within the Internet.The associated servers cooperate to schedule each peer todownload its unique portion of the content. In addition,the servers schedule the distribution pattern for exchangingcontent between the peers. The results indicate that approximately90% of the telecommunication cost is saved with asfew as 10 peers.
