Abstract:

Most of the existing research work in mobile ad hoc networking is
based on the assumption that a path exists between the sender and the
receiver. On the other hand, applications of decentralised mobile
systems are often characterised by network partitions. Examples
include emergency support networks, military field networks,
infostation-based systems for connectivity in remote areas and data
collection in sensor networks for wildlife monitoring. As a
consequence delay tolerant networking research has received
considerable attention in the recent years as a means to obviate to
the gap between ad hoc network research and real applications. In
this talk I will describe our advances in the use of opportunistic
routing in decentralized networks containing frequent and changing
partitions. I will describe our context-aware routing model which
uses Kalman Filters to predict the best carrier for messages among
neighbouring nodes and its extensions to mobile sensor networks and
publish/subscribe applications in human networks. I will report about
the evaluation of the approaches through simulation with both social
mobility and animal mobility models.
