Device-to-device (D2D) communication has been regarded as a major technology to improve spectrum utilization and to offload the traffic from cellular base station. D2D peer discovery, as a critical procedure, attracts a lot of attentions. Furthermore, combination with the mobile social network (MSN) is an efficient solution to improve the establishment of D2D pairs. However, limited work has been...
Recent advances of loop interference cancellation techniques enable full-duplex relaying (FDR) systems, which transmit and receive simultaneously in the same band with high spectrum efficiency. Unlike the existing works, in this paper, we study the energy efficiency aspect of resource allocation in FDR systems. We consider a OFDMA cellular network, where a shared FDR is deployed at the intersection...
This paper discusses the problem of minimizing the energy used to transmit packets over a memoryless channel, with a constraint on the delay suffered by packets and a constraint on peak transmitter power. The problem is studied within discontinuous reception (DRX) supported system. Specifically, we seek a DRX-compatible transmission policy that can solve the problem without the knowledge of fading...
Biasing cell association (BCA) is an effective and easy-to-implement load balancing technology in small cell networks (SCN). The existing studies are mainly respect to the static BCA strategy which is not appropriate for the non-uniform traffic distribution scenarios. In this paper, we address the problem of load balancing in SCN where the small cell base stations (SCBSs) are underlaid deployed within...
With the dense deployment of femtocell, interference control is becoming a major challenge for resource management in femtocell networks. Most of the existing works focus on improving throughput or reducing the total power consumption respectively, neglecting the energy consumption. In this paper, we investigate energy efficiency aspect in a femtocell network and propose an interference-mitigation...
In wireless mobile peer-to-peer (P2P) networks, multiple sources can provide multimedia file sharing at the same time. The selection of multiple sources is one of the key issues in the design of a multi-source transmission system in wireless mobile P2P networks. In this paper, we propose a distributed multi-source sender selection scheme to maximize the receiving data rate and minimize the energy...
To resolve the topology mismatch problem when applying peer-to-peer (P2P) file sharing over mobile ad hoc networks (MANETs), a cross-layer protocol is proposed by combining P2P file discovery with the route discovery process at the network layer. In this protocol, the functionality of conventional routing protocols is extended to identify the file discovery request, and P2P connections are established...
Multi-source multimedia transmission is a popular architecture in wireless mobile peer-to-peer (P2P) networks. Most of previous work on wireless mobile P2P networks concentrates on the protocols and network structures, and consequently ignores the multiple senders scheduling problem. In this paper, we present a distributed algorithm for scheduling the multiple senders for multi-source transmission...
