This paper presents the results for a combined Coordinated MultiPoint (CoMP) and Dynamic Sectorization (DS) approach for energy saving at the Base Station (BS) in LTE-A cellular networks. The DS scheme is based on ecological self-organization where BSs are dynamically reconfigured based on their tempo-spatial traffic diversity. The compatibility of CoMP and DS is explored and improved upon independent...
Physical-layer network coding (PNC) is a promising technique to improve the performance of wireless networks. In a traditional setting, two packets are encoded with PNC. However, encoding three or more packets with PNC may further enhance the performance. A straightforward method to achieve multiple packet encoding is to further process the superposed signal from different source node-pairs at the...
In this paper, by exploiting the availability of multiple cellular radio access networks (RANs), we propose a novel two-level cooperative access network framework for superior energy efficiency. Geographically co-located RANs mutually cooperate each other through the combined use of base transceiver station (BTS) level intranetwork cooperation and RAN level internetwork cooperation. By jointly applying...
The aim of this paper is to study the effect of cooperation on system delay, quantified as the number of retransmissions required to deliver a broadcast message to all intended receivers. Unlike existing works on broadcast scenarios, where distance between nodes is not explicitly considered, we examine the joint effect of small scale fading and propagation path loss. Also, we study cooperation in...
