Current large-scale computing services, such as online social networking and web searching, make the wired links in the data centers with an Ethernet infrastructure oversubscribed. Therefore, researchers consider to augment the data centers with wireless communication, called a hybrid data center network (HDCN), to improve the communication flexibility and network capacity. In this paper, we investigate...
In this paper, we consider joint optimization of end-to-end data transmission and resource allocation for Wireless-Infrastructured Distributed Cellular Networks (WIDCNs), where each base station (BS) in a cell is connected with its neighboring BSs via wireless links, and a mobile station (MS) can access one or multiple adjacent BSs simultaneously through time-varying OFDMA channels. The communications...
In this paper, we consider a 2-hop wireless relay network where more than one relay is available. We explore optimal relay selection for decode-and-forward cooperative protocol to minimize the outage probability under a short-term power constraint. We first investigate the impact of power control on relay selection from a capacity point-of-view. Assuming the knowledge of channel gain magnitudes, we...
