| Popis: | In order to accommodate increasing need and offer communication with high performance, both vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communications are exploited. The advantages of static nodes and vehicular nodes are combined to achieve an optimal routing scheme. In this paper, we consider the communications between a static node and the vehicular nodes moving in an adjacent area of it. The adjacent area is defined as the zone where a vehicular can communicate with the static node within maximum two hops. We only consider single-hop and two-hop transmissions because these transmissions can be considered as building blocks to construct transmissions with a higher number of hops. Different cases in which an uplink or a downlink for the two-hop user combined with an uplink or a downlink for the single-hop user correspond to different CDR schemes. Using side information to intentionally cancel the interference, Network Coding (NC), CDR, overhearing and multi-way schemes aggregate communications flows in order to increase the performance of the network. We apply the mentioned schemes to a V2I network and propose novel schemes to optimally arrange and combine the transmissions. Comment: 15 pages, 5 figures |
