Device-to-device (D2D) communication is a communication technology that enables one device to transmit data directly to the other device in proximity instead of conveying data via infrastructure. Without the coordination of infrastructure, multiple access for D2D communication is performed in a distributed manner. Even though contention-based distributed multiple access scheme is widely adopted in the existing D2D systems, the excessive contention overhead with a large number of devices makes contention-based scheme lose scalability. In this paper, we present the rationale behind the design of a new fully distributed multiple access scheme based on contention-free resource request and response message exchange, which is proposed for IEEE 802.15.8. Through the results of simulations with full buffer and VoIP traffic model, we show that the presented scheme achieves scalability with the help of orthogonal requests and responses. © 2014 Global IT Research Institute (GIRI).
