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)
The adaptive routing protocol recently proposed by researchers for opportunistic networks often makes an assumption that when each node makes an intelligent decision of choosing a best forwarder node to route its messages, the chosen forwarder will often have a large buffer storage and will always altruistically devote its resources for forwarding those(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)
A lot of research effort has been put by researchers in developing routing protocols for Mobile Ad-hoc Networks (MANETs). Each protocol proposed and designed so far has its own merits and demerits. Researchers around the world continue to develop novel, advanced routing protocols that can route messages towards their destination in an efficient way while(More)
Intermittently connected opportunistic networks experience frequent disconnections and shorter contact durations. Therefore routing of packets towards their destinations needs to be handled from various points of view. Predictability and connectedness are two information that mobile nodes, which participate in an opportunistic content distribution,(More)
Research in overlay and P2P networking has been tightly focused on fundamentals in the last few years, leading to developments on a range of important issues. The time has come to integrate these insights into existing and new systems. We see this as a vital part of the effort to influence the development of Internet services and arrive at a generalized(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 opportunistic 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)
Routing packets towards their destinations is a key task in mobile ad-hoc networks due to nodal mobility and dynamic topology of the network. Many well performing routing protocols for MANETs are proposed and implemented by considering these inherent properties. ad-hoc On-demand Distance Vector (AODV) is one such protocol which performs better among similar(More)
