摘要：Cellular networks are currently facing severe traffic overload problems caused by excessive traffic demands. Offloading part of the cellular traffic through other forms of networks, such as Delay Tolerant Networks (DTNs) and WiFi hotspot, is a promising solution since these networks can only provide intermittent connectivity to mobile users, utilizing them for cellular traffic offloading may result in a non negligible delay. As the delay increases, the users’ satisfaction decreases. we investigate the tradeoff between the amount of traffic being offloaded and the users’ satisfaction. We provide a novel incentive framework to motivate users to leverage their delay tolerance for cellular traffic offloading To minimize the incentive cost given an offloading target users with high delay tolerance and large offloading potential should be prioritized for traffic offloading To effectively capture the dynamic characteristics of users’ delay tolerance our incentive framework is based on reverse auction to let users proactively express their delay tolerance by submitting bids. We further illustrate how to predict the offloading potential of the users by using stochastic analysis for both DTN and WiFi cases Extensive trace-driven simulations verify the efficiency of our incentive framework for cellular traffic offloading Block Diagram the proposed System to implications Greedy and Enhanced greedy algorithms.
