Popis:	The increasing number of connected vehicles in densely populated urban areas provides an interesting opportunity to counteract the high wireless data demands in high density and highly mobile scenarios. The idea is to support the macro base station (BS) with a secondary communication tier composed of a set of smart and connected vehicles that are in movement in the urban area. As a first step towards a comprehensive cost-benefit analysis of this architecture, this paper considers the case where these vehicles are equipped with femto-mobile Access Points (fmAPs) and constitute a mobile out-of-band relay infrastructure. In particular, three techniques to select an fmAP (if more than one is available) are proposed and the maximal feasible gain in the packet delivery rate and data rate as a function of the vehicle density, average vehicle speeds, handoff overhead cost, as well as physical layer parameters is characterized. The analytical and simulation results provide a first benchmark characterizing this architecture and the definition of guidelines for its future realistic study and implementation. Comment: Technical Report of detailed mathematical proofs for supporting "From Connected Vehicles to Mobile Relays: Enhanced Wireless Infrastructure for Smarter Cities", which is to appear in IEEE Global Communications Conference, Dec. 2016
