Dynamic multiagent method to avoid duplicated information at intersections in VANETs
Vehicular ad hoc networks (VANETs) allow vehicles to contact one another to provide safety and comfort applications. However, mobility is a great challenge in VANETs. High vehicle speed causes topological changes that result in unstable networks.…

Enabling relay selection in non-orthogonal multiple access networks: direct and relaying mode
In this paper, we consider downlink non-orthogonal multiple access
(NOMA) in which the relay selection (RS) scheme is enabled for cooperative networks. In particular, we investigate impact of the number of relays on system performance in term of…
