Abstract : The recent boost up of mobile data consumption is straining 3G cellular networks in metropolitan areas and is the main reason for the ending of unlimited data plans by many providers. To address this problem, we propose the use of opportunistic delegation as a data traffic offload solution by investigating two main questions: (i) ''How to gain insights into social mobile networking scenarios?'' and (ii) ''How to utilize such insights to design solutions to alleviate overloaded 3G networks?''. The purpose of our solution is to leverage usage of mobile applications requiring large data transfers by channeling the traffic to a few, socially important users in the network called VIP delegates. To identify VIPs, we propose different strategies that only need short observation periods of the network (around 1 week) to cover several months of activity. The proposed VIP selection strategies are based on social network properties and are compared to the optimal solution (that covers 100% of users with minimum number of VIPs). Through several experiments using real and synthetic traces, we show the effectiveness of VIP delegation both in terms of coverage and required number of VIPs -- down to 7% in average of VIPs are needed in campus-like scenarios to offload about 90% of the traffic.
