ABSTRACT
Until recently, the vast majority of research in wireless and mobile networks focused on so-called Mobile Ad Hoc Networks (MANETs), where relatively stable end-to-end paths are the norm. More recently, research has focused on a different, Intermittently Connected Network (ICN) paradigm, where stable end-to-end paths are the exception and intermediate nodes may store data while waiting for transfer opportunities towards the destination. Protocols developed for MANETs generally do not work in ICNs since the connectivity assumptions are so different. In this talk I will first give an overview of ICNs and the types of challenges involved in their design and operation. I will then discuss our work in the WAM (wireless and mobile) Continuum project which is based on the simple but powerful observation that MANETs and ICNs fit into a continuum that generalizes these two previously distinct categories. Building on this observation, our work develops a framework that goes further to scope the entire space of wireless and mobile networks. I will summarize two efforts: The first gives clues of the fundamental relationship between ICNs and MANETs by unifying the use of message ferrying in ICNs with the well-known use of connected dominating set-based routing in MANETs. The second effort aims at developing a formal WAM Continuum framework where a network can be characterized by its position in this continuum. Certain network equivalence classes can be defined over subsets of this WAM continuum and this classification can be used to inform network design and operation. I will demonstrate how the unified view enabled by our framework can be used as a systematic, formal descriptive and evaluative tool.

Contention aware mobility prediction routing for intermittently connected mobile networks
This paper introduces a novel multi-copy routing protocol, called predict and forward (PF), for delay tolerant networks, which aims to explore the possibility of using mobile nodes as message carriers for end-to-end delivery of the messages. With PF, ...
Exploiting the influence of infostation system on delay-tolerant networks
Heterogeneous delay-tolerant network DTN is a trend in the future. This paper investigates the heterogeneity of DTNs by assuming that among the regular DTN nodes some infostations are equipped with large-capacity buffer and connected by high-speed links ...
Priority-based approach to mitigate selfish misbehaviour in delay tolerant network
Delay tolerant networks (DTNs) is a solution to challenged networks which suffer from intermittent connectivity or high delay, thereby offering delay-tolerant support. DTN focuses on minimising delay and maximising forwarding and delivery ratio of data ...
