Cellular networks (e.g., 3G) 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 hotspots, is a promising solution. However, 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. In this paper, the authors investigate the tradeoff between the amount of traffic being offloaded and the users' satisfaction. They provide a novel incentive framework to motivate users to leverage their delay tolerance for cellular traffic offloading.
