	abstract = {3G networks are currently overloaded, due to the increasing popularity of various applications for smartphones. Offloading mobile data traffic through opportunistic communications is a promising solution to partially solve this problem, because there is almost no monetary cost for it. We propose to exploit opportunistic communications to facilitate information dissemination in the emerging Mobile Social Networks (MoSoNets) and thus reduce the amount of mobile data traffic. As a case study, we investigate the target-set selection problem for information delivery. In particular, we study how to select the target set with only k users, such that we can minimize the mobile data traffic over cellular networks. We propose three algorithms, called Greedy, Heuristic, and Random, for this problem and evaluate their performance through an extensive trace-driven simulation study. Our simulation results verify the efficiency of these algorithms for both synthetic and real-world mobility traces. For example, the Heuristic algorithm can offload mobile data traffic by up to 73.66 percent for a real-world mobility trace. Moreover, to investigate the feasibility of opportunistic communications for mobile phones, we implement a proof-of-concept prototype, called Opp-off, on Nokia N900 smartphones, which utilizes their Bluetooth interface for device/service discovery and content transfer.},

	abstract = {In this research, we propose to modify and extend epidemic routing used in intermittent networks. In particular, we propose to include immunity-based information disseminated in the reverse once messages get delivered to their destination. The goal is to design a more efficient routing protocol in terms of resource utilization. The idea is to analyze and evaluate the network performance using an immunity scheme in the context of epidemic routing and its variants. The reverse dissemination of such information requires minimal resources and the tradeoff in timely purging of delivered messages can be significant. We are using ns2 to implement a detailed simulation of the proposed immunity-based epidemic routing.},

	abstract = {In the near future, we will be surrounded by ubiquitous wireless networks and so information dissemination for mobile users is a key issue. Hybrid push-pull constitutes a very effective and scalable solution. Our contribution is twofold. First we provide a new analysis that takes into account the user mobility. We argue that in a highly mobile setting, analysis and optimization goals discussed in past papers become irrelevant, since the most important aspect of the system is not delay, but rather the ability to answer as many queries as possible. As we show, the optimal pull-push bandwidth ratio depends on the mobility patterns of the users. Second, we use our findings to build Mobile-Cache, a system that can efficiently answer multiple queries over a wireless environment.},
