As the number of proposed routing algorithms has grown, it has become difficult to fully understand their similarities and differences. Although published results clearly show different performance results between algorithms, it can be difficult to pinpoint which of their characteristics are most responsible for their performance differences. This thesis proposes an architectural framework to define the underlying features that Delay Tolerant Network routing algorithms are composed of. Popular routing algorithms from research are discussed and shown to be compositions of the proposed architectural features, thereby validating the architecture itself. The architectural framework is also shown to be a useful guide to developing a modular and configurable simulation platform. Algorithms from literature were implemented as a composition of features, which can easily be modified and combined later to define and implement new algorithms. Better understanding the underlying structure and similarities between different routing algorithm approaches is key to truly analyzing their performance and obtaining a deep understanding of which components of an algorithm have the most influence, both positively and negatively, on the results. Armed with this knowledge, designers of Delay Tolerant Networks can more easily determine the proper composition of routing algorithm features to best fit their needs.application/pdfengDelay tolerant networkingRouting architectureNetwork simulationDTNRouting algorithmsthesis2011-07-112152/ETD-UT-2011-05-3075
