Description The "Aether" communication system, developed in collaboration with Tierra Telematics, allows devices (whether mobile and fixed) located in environments that lack of WAN connectivity, to set up an ad hoc network, which exploits the movement of devices through the store-carry-and-forward communication paradigm, to allow data to be transparently propagated from one device to another. Such a network is called Delay/Disruption Tolerant Network (DTN), and is characterized by short-range communications between devices, unstable connections, variable topologies.
The thesis proposal concerns the investigation of possible solutions to the problem of routing between devices (nodes) belonging to the Aether communication system, where the classical protocols are ineffective because of the high instability of the network. In particular, focus is given on the design of a protocol that allows to build a topological model distributed among the nodes. Nodes exchange partial information about the known topology; since the topology is not stable, this information will be statistical in nature. At steady each node will have a statistical topology, in which each link or path exists with a certain probability and features a certain estimated latency.
The long-term idea is that each node can take advantage of this probabilistic topology to make smart routing decisions about store-carry-and-forward communication.
