Abstract

In this paper,a novel network architecture that incorporating cooperative diversity techniques to increase the cellular network throughput is proposed.We design a relay selection strategy in this network architecture design,where the proxy node will select a relay node based on the channel quality and nodes'residual energy to enhance the users'fairness among the nodes. Moreover,we propose a novel power allocation scheme to minimize the power consumption of the whole network.The implementation of the algorithm is given to show that the proposed relay selection and power allocation scheme can provide significant network performance improvement in terms of network power consumption and quality of service due to the using of cooperative diversity techniques.
基于合作分集的蜂窝网络中继选择与功率分配方案
本文提出了一种利用协同分集技术提高蜂窝网络吞吐量的新型网络结构。在网络架构设计中,我们设计了一种中继选择策略,代理节点根据信道质量和节点剩余能量选择中继节点,以增强节点间用户的公平性。此外,我们还提出了一种新的功率分配方案,以使整个网络的功耗最小。算法的实现表明,由于采用了合作分集技术,所提出的中继选择和功率分配方案可以在网络功耗和服务质量方面提供显著的网络性能改进。
