The wide spread use of small portable wireless devices in the recent years has been observed by researchers and many are interested in exploring content distribution using these devices [1], [2]. The properties of these devices, such as small size, wireless connectivity, limited storage capacity etc., combined with the manner in which they are used and(More)
Opportunistic networking is a new communication paradigm. Content Distribution in opportunistic networks is challenging due to intermittent con-nectivity, short connection durations and a highly dynamic topology. Research is needed to develop new applications and protocols that can distribute content in opportunistic networks. This thesis explores and(More)
Opportunistic networking is a new communication paradigm which explores the potential of inter-device contacts due to human mobility [3, 5]. Intermittent connectivity, non existence of an end-to-end path between nodes and extreme dynamism in topological structure are inherent characteristics of opportunistic networking [2, 5]. In opportunistic networking(More)
—Predicting future contact opportunities in oppor-tunistic networks can assist mobile nodes to make intelligent decisions on efficient content forwarding and can greatly improve the message delivery ratio. But predicting future contacts has to depend on the past history of contacts and then naturally a question arises on how valid is the use of past history(More)
