The objective of this thesis is the study and implementation of a Vehicular Delay Tolerant Network (VDTN) system for a fleet of vehicles, and the evaluation of its data carrying potential. The implementation relies on commodity hardware and communication using "WiFi" (IEEE 802.11) transceivers. We also detail the steps necessary for the accurate simulation of realistic, daily routines, of vehicular fleets serving an urban road network. We use as our example a fleet of service vehicles operating in the city of Lethbridge, Alberta. We analyze the dynamics of encounters among fleet vehicles throughout a typical working day, and introduce a Markovian model capturing the encounter distance dynamics. We can then translate the encounter distance dynamics to, corresponding, communication throughput dynamics. We perform data collection of IEEE 802.11 point-to-point throughput vs. distance measurements, which, in conjunction with the Markovian model, allows to derive the expected data carrying volume introduced by the VDTN. The results demonstrate that the data carrying capacity of the VDTN exceeds what is needed by typical vehicle monitoring applications. The surplus capacity can be used for delivering value-added services, such as data collection from external wireless sensor networks.
