VIP delegation: Enabling VIPs to offload data in wireless social mobile networks

Abstract

Abstract-We propose the use of opportunistic delegation as a data traffic offload solution to the recent boost up of mobile data consumption in metropolitan areas, 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 selected important users in the network called VIP delegates. 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). Our extensive experiments with real and synthetic traces 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 campuslike scenarios to offload about 90% of the traffic.

DROid: Adapting to individual mobility pays off in mobile data offloading

“…Instead, we are interested in very short maximum reception delays, in the order of minutes, as otherwise users would not realistically accept to trade-off reception delays for cellular capacity. Stateof-the-art solutions, benefiting from more relaxed reception constraints, can take advantage of a sort of stochastic regularity in contact patterns of users [2], [3], [4]. Centralized optimization frameworks based on Monte Carlo sampling [2] or temporal reachability graphs [18] require the complete contact graphs among users, and are known to have high computational complexity.…”

“…Barbera et al analyze contacts between endnodes in order to select a subset of seed VIP users that are socially important in terms of centrality for the network. The main idea is to turn these few central VIP nodes into data forwarders between other nodes and the Internet [3]. Ioannidis et al assume that the cellular infrastructure has a fixed bandwidth that should be allocated between different end-users.…”

“…Nevertheless, expenses to buy more licensed band or to build more base stations are very high; unfortunately, the increase in network capacity brought by these methods will hardly keep up with traffic growth. Recent studies disclosed an alternative solution when many colocated users are interested in the same contents [2], [3], [4].…”
