Device-to-device (D2D) communication has become a key technology in the fifth-generation cellular networks. Resource allocation is critical to ensure satisfactory performance. However, most existing resource allocation policies focus on delay-unaware performance metrics, such as throughput and power consumption, thus being effective only in delay-insensitive scenarios. To overcome this problem, in...
Femtocell is a promising technology which can significantly improve the spectrum efficiency and system capacity of wireless cellular networks. However, densely and randomly deployed femtocells may experience severe interfemtocell interference due to rough-and-tumble spectrum reuse with unconstrained transmit power. Different from traditional macrocell scenarios, there is no central controller available...
Device-to-device (D2D) communication is envisioned as a promising technology in future cellular networks. In this paper, we investigate the delay-aware resource allocation and power control algorithm for delay-sensitive D2D communications underlaying cellular networks. With the objective to minimize the average delay and average drop rate, we formulate the optimization problem as an infinite horizon...
