Conference Proceeding: High throughput relay selection and resource allocation in multihop cellular networks
[show abstract] [hide abstract]
ABSTRACT: In recent years, there has been a strong interest in incorporating multihop relaying strategies in cellular systems to develop Multihop Cellular Networks (MCNs). This increases the network capacity, improves its coverage and reduces transmit power levels. In this paper, a joint relay selection and resource allocation algorithm is proposed to maximize the throughput. The proposed algorithm is evaluated and compared with three other existing algorithms. Simulation results show that our proposed algorithm achieves at least 30% more throughput than those of others when there are 10 active users in the cell.Electrical and Computer Engineering, 2009.

Conference Proceeding: On the Performance of a New Relay Selection Scheme in Multihop Cellular Networks
[show abstract] [hide abstract]
ABSTRACT: The cellular networks are expected to change to Multi-hop Cellular Networks (MCNs). While a mobile station and the base station have a direct link in a conventional cellular network, in MCN, mobile stations with unsatisfying path to the base station, could instead relay their data through other mobile stations with better channel conditions. This can improve coverage and capacity, and reduce the total transmission power, but its efficiency depends deeply on the relaying strategy used. This paper investigates an efficient relaying method in multihop cellular networks. In the new relay selection scheme, mobile station selects the best channel coefficient between relay station and base station in each coherence time. The performance improvement due to the proposed scheme is demonstrated through simulation results.Computer and Electrical Engineering, 2008. ICCEE 2008. International Conference on; 01/2009
