In this paper, we focus on the scheduling problem in multi-channel wireless networks, e.g., the downlink of a single cell in fourth generation (4G) OFDM-based cellular networks. Our goal is to design efficient scheduling policies that can achieve provably good performance in terms of both throughput and delay, at a low complexity. While a recently developed scheduling policy, called Delay Weighted...
Ad-hoc wireless multi-hop network is communication network that consist of wireless nodes, placed together in an ad hoc manner, with minimal prior planning. All nodes have routing capability and forward data packets for other nodes in multi-hop fashion. Since many applications have QoS (quality of service) requirements such as delay and throughput, it is imperative that the wireless part of the communication...
Nowadays cellular systems operate with frequency reuse one, where adjacent cells use the same frequency band. Use equipments (UEs) located at cell edge are mostly affected by the resulting co-channel interference. In addition, cell edge UEs suffer from their weak carrier signal strength. This paper proposes a new method to increase the performance of cell edge UEs by means of information exchange...
Cellular systems in general suffer from co-channel interference, when simultaneous transmissions in other cells use the same physical resources. In order to mitigate such co-channel interference cooperating Base Stations (BSs) can perform joint multi-antenna signal processing across cell borders. This paper describes a concept of distributed cooperation, where BSs communicate directly via a BS-BS...
