Network selection is one of the key issues in heterogeneous wireless networks. However, very few efforts have been made on both algorithm and management of network selection to satisfy the individual requirements of every single user, so as to attract customers in the future user centric business mode. This paper takes the following steps toward addressing this problem: 1) a novel user preference...
This paper proposes a distributed optimal relay selection scheme in wireless multi-hop cooperative networks where the wireless channels are modeled as first-order finite-state Markov channels (FSMCs) and adaptive modulation and coding (AMC) is applied. The FSMC model is used to approximate the time variations of the average received signal-to-noise ratio (SNR). The state of a relay consists of the...
Service oriented management are focused on service quality rather than network performance. Evaluation based on customer perception of service quality is playing a very important role in service supporting and management. Effective evaluation of service quality can help service provider to increase customer satisfaction. In this paper, we propose three layers evaluation architecture and give the analysis...
Recently many researches have been focused on heterogeneous cooperative wireless networks in both academy and industry. This paper gives a comprehensive study of resource scheduling techniques for next generation heterogeneous cooperative wireless networks. Specifically, we study the cooperative nodes selection, cooperative power allocation, cooperative scheduling algorithms and handover management...
An important aspect of wireless networks is the dynamic behavior, cross-layer design is the central technique to cope with and utilize this behavior. In this paper, we present the cross-layer design for adaptive modulation and coding (AMC) with HARQ. For each of two widely used HARQ techniques-chase combining and incremental redundancy, the close-form functions of average retransmission time, average...
