This paper presents an easy-to-use sensor aimed for traffic safety applications using visible lightcommunications. A central problem in this area is the design of a suitable sensor able to enhance the conditioning of the signal and to avoid disturbances due…

Cooperative communication exploits spatial diversity via relay node antennas in order to increase data rates in wireless networks. Relay node selection therefore plays a critical role in system performance. This study examines the problem of relay node selection in cooperative networks, in…
