Framework for Collaborative Download in Wireless Mobile Environment

Proliferation of wireless technology and increasing demand of data result in traffic congestion. Congestion due to wireless Internet is increasing at an exponential rate and 50% of this traffic is due to video. However, as popularity of files in Internet follows power law and people with similar interest meet/interact more frequently, there is a good probability that many users in proximity would like to download similar files. In this paper we exploit this probability and propose a scheme for collaborative download where a number of users in proximity collaborate with each other for downloading a set of files. We have also developed a prototype in android platform, with basic features of collaborative download.
