OPPORTUNISTIC ROUTING AND DTN
In this work, the focus is on the use of Delay Tolerant Networks (DTN) as the ideal candidate for complementing existing communication infrastructures where deployment practicalities and costs are a prohibitive factor. This is important, as we still find many places in the world where connectivity is unreliable or not available at all and there is a need for data transfers to and from such locations, e.g., for processing data gathered by sensors or medical devices, for providing basic communications such as email, etc.
Due to the disconnected nature of DTNs (i.e. the absence of an end-to-end path from source to destination) routing of data is naturally a challenging issue. As DTNs have found their way in a number of application scenarios, different routing approaches were devised to support the particular deployments and improve performance of data delivery. In this work, the performance of various routing algorithms for DTNs in a maritime network environment is examined and evaluated. Actual vessel movement data are used in order to have pragmatic results and we assess these algorithms with regards to their delivery probability, delivery delay and hop count, as well as resource usage. Based on our findings, we present our considerations for developing an improved DTN routing algorithm that will perform better within the context of a maritime network, and mainly improve existing ones on delivery probability and resource usage.
