How to balance efficiency and fairness concerning resource allocation in cooperative networks is an interesting research problem. Under the assumption of decode-and-forward (DF) cooperative scheme, this paper studies power allocation problem in user cooperation networks with two users transmitting to a common destination. Specifically, centralized and distributed power allocation schemes are presented...
In this paper, a user capacity model, combining both the modulation and coding scheme (MCS) distribution model and resource allocation model, is developed to analyze the system performance of wireless communication systems. From the model, we can intuitively calculate the system capacity from MCS distribution. An example based on relay networks is used to quantify the benefit of deploying relay stations.
This paper presents a resource allocation framework for the transmission of heterogeneous services in two-hop orthogonal frequency division multiplexing (OFDM) cooperative relay systems. An optimal adaptive power and subcarrier allocation scheme is proposed to maximize the system throughput while satisfying the quality of service (QoS) requirements of both the real-time (RT) and nonreal-time (NRT)...
The cross-layer concept originated almost ten years ago with the aim of taking the most advantage from the difficult wireless media to break the barriers imposed by the layered transmission. One of the domains where cross-layer design has been more investigated is radio resource allocation, since current and future networks need to provide wireless connectivity to heterogeneous users, offering many...
