A Transmission Prediction Mechanism Exploiting Comprehensive Node Forwarding Capability in Opportunistic Networks

Opportunistic Forwarding in Challenged Networks

LEE, CHUL-HO. Design and Analysis of Opportunistic Forwarding in Challenged Networks. (Under the direction of Dr. Do Young Eun.) Challenged networks are those networks, e.g., mobile opportunistic networks (MONs), a.k.a., delay/disruption tolerant networks, and power-constrained or duty-cycled wireless sensor networks (WSNs), where traditional Internet architectures fail to ensure end-to-end com...

Modelling Social-Aware Forwarding in Opportunistic Networks

Opportunistic networks are one of the most promising evolutions of the traditional Mobile Ad Hoc Networks paradigm. Communications in an opportunistic network rely on the mobility of the users: each message is handed over from node to node, making hop-by-hop decisions to select the node that is better suited for bringing the message closer to its destination. Algorithms exploiting social-awaren...

Mobile-relay Forwarding in Opportunistic Networks

Exploiting user interest similarity and social links for micro-blog forwarding in mobile opportunistic networks

Micro-blogging services have recently been experiencing increasing success among Web users. Different to traditional online social applications, micro-blogs are lightweight, require small cognitive effort and help share real-time information about personal activities and interests. In this article we explore scalable pushing protocols that are particularly suited to the delivery of this type of...

A Packet Forwarding Protocol in Coal Mine Opportunistic Networks

—A packet forwarding protocol based on terminals’ Markov mobility model (TMM) is proposed for coal mine poor connectivity in opportunistic networks since its complex environment. First, a Markov model is established for predicting the probability of terminals’ encounter. Then the network-delay in the condition of next selected relay-terminal (NDT), the probability of terminal encounter with de...
