Abstract:
Last years have witnessed the appearing of the vehicular network concept, whose applications can potentially raise road safety, reduce pollution and manage car fleets efficiently. Two communication technologies stand out as support for this kind of networks, the Long Term Evolution (LTE) and the 802.11p/Wireless Access in Vehicular Environments (WAVE). Given the particular characteristics of this kind of networks, most studies are executed by means of network simulators and mobility models, the latter to simulate the impact of mobility on communication activities. This work describes the implementation of two different algorithms for data dissemination, based on LTE and 802.11p respectively, and the implementation of a new mobility model for the ns-3 network simulator. The work comprises the design of two different algorithms for data dissemination based on the publish/subscribe paradigm, the development of applications implenting the algorithms in the ns-3 framework, the development of a mobility model that exploits an external travel-planning API such as Google Maps to produce the mobility traces for nodes. The applications described in this work allow to analyze the performance of data dissemination depending on which algorithms are used, the density of nodes in the network, the route followed by the nodes, and other parameters. The mobility model developed in the context of this thesis represents a contribution by itself, since it provides network researchers with realistic node mobility, without forcing them to resort to complex road traffic simulator. The module has been included into the release of the ns-3 network simulator platform.
