Radio resource management of D2D communication

Device-to-Device (D2D) is considered as a promising technique to improve resource utilization and provide new application in future wireless networks. This paper addresses the problem of radio resource allocation for D2D communication. Basically, resource allocation can be carried out in centralized or distributed manner. In this paper we discuss the mechanisms of distributed resource allocation and propose a new medium access mechanism to reduce collision probability. The collision probability is shown to be lower than that of the widely adopted CSMA/CA mechanism both analytically and numerically.
