  • Radio Resource Management in wireless LANs
    IEEE Communications Magazine, 2004
    Co-Authors: Alex Hills, B. Friday
    Abstract:

    Some chief information officers and information technology managers are reluctant to deploy wireless LANs. Among their concerns are reliability, availability, performance, and deployment. Each of these concerns can be directly addressed through the Radio Resource Management techniques used in a new generation of wireless LAN equipment. The new capabilities include dynamic channel assignment, dynamic power control, and load sharing. Changing from the relatively static Radio Resource Management techniques generally in use today to dynamic methods like those highlighted in this article helps to increase the capacity and improve the performance of large-scale wireless LANs.

  • VTC Spring - Radio Resource Management via Spectrum Trading
    VTC Spring 2008 - IEEE Vehicular Technology Conference, 2008
    Co-Authors: C. M. Chin, Sverrir Olafsson, B. Virginas, G. Owusu
    Abstract:

    The growth in the deployment of wireless systems and technologies shows that in this rapidly evolving and expanding environment, Radio Resource Management (RRM) is fast becoming the most significant aspect in the provisioning of quality of service (QoS) for wireless networks. As Radio spectrum is a finite Resource, new approaches are therefore needed to maximize the existing spectrum to ensure the wireless users' and network providers' QoS requirements are met. In this paper we propose a novel Radio spectrum trading via derivatives contracts as a means to address short-term demands for spectrum whilst ensuring end-to-end QoS is met.

  • WCNC - Multi-access Radio Resource Management using multi-agent system
    IEEE Wireless Communications and Networking Conference 2006. WCNC 2006., 2006
    Co-Authors: Feng Zhiyong, Zhang Ping, Yu Kai, Ji Yang, Zhang Yongjing
    Abstract:

    Coexistence of heterogeneous networks such as cellular, wireless local area network (WLAN), ultra-wideband (UWB) etc. brings new challenges. It is perceived that current Radio Resource Management mechanism cannot meet the requirements of multi-Radio access technologies (multi-RATs). This paper proposes a novel intelligent multi-agent Radio Resource Management system, which is self-organized and distributed to ensure the coexistence of multi-RATs. Radio Resource is managed by a macro control and Management system using control factors and validation mechanism, instead of micro control for individual users. The goal is to increase Radio Resource utilization efficiency, maximize system capacity and meet the QoS requirements of different services

  • Joint Radio Resource Management based on IEEE 802.11e MAC
    Journal of Chongqing University of Posts and Telecommunications, 2005
    Co-Authors: Zhang Ping
    Abstract:

    Joint Radio Resource Management(JRRM) is designed for multi-Radio Resource Management in heterogeneous wireless network,which aims to improve heterogeneous Radio Resource utilization.To meet the requirements of different Radio access network for JRRM,JRRM based on IEEE 802.11e MAC is proposed and the joint session access control and jont Resource scheduler are described.Finally,it comes to the conclusion that JRRM based on IEEE 802.11e MAC can improve the heterogeneous network performance.

  • VTC Spring - Cooperation Techniques and Architecture for Multi-access Radio Resource Management
    2006 IEEE 63rd Vehicular Technology Conference, 1
    Co-Authors: Feng Zhiyong, Zhang Ping
    Abstract:

    Next-generation wireless networks will be a conglomeration of different networks technologies and will support multiple Radio access technologies (Multi-RATs). This will put high demands on Radio Resource Management support. In this paper, we describe an intelligent multi-agent Radio Resource Management system, which is self-organized and distributed to ensure the coexistence of multi-RATs. This paper discusses how to implement macro control and Management by using control factors instead of micro control concerning individual users, and also describes the mechanism of coexistence of multi-RATs. Further, message flow and open questions are discussed

  • Joint Radio Resource Management for heterogeneous wireless systems
    Wireless Networks, 2011
    Co-Authors: Javier Gozalvez, M. C. Lucas-estan, Joaquín Sánchez-soriano
    Abstract:

    Heterogeneous wireless systems are characterized by the physical coexistence of a variety of Radio access technologies with different, but also complementary, technical characteristics and performance. A key aspect of heterogeneous systems is then the implementation of efficient joint Radio Resource Management mechanisms. In this context, this paper presents and evaluates novel joint Radio Resource Management techniques based on the CEA bankruptcy distribution rule. The proposed policies base their distribution decisions on the system conditions and the varying quality of service requirements present in multimedia scenarios. The obtained results demonstrate that the proposed policies can efficiently distribute the Radio Resources with a low computational cost.

  • Bankruptcy-based Radio Resource Management for Multimedia Mobile Networks
    Transactions on Emerging Telecommunications Technologies, 2011
    Co-Authors: M. C. Lucas-estan, Javier Gozalvez, Joaquín Sánchez-soriano
    Abstract:

    The transmission of bandwidth-demanding multimedia applications in capacity-constrained mobile Radio networks requires optimizing the usage and assignment of Radio Resources following the varying quality of service requirement characteristics of multimedia traffic environments. Considering the capacity of the bankruptcy theory to deal with situations where the demand for Resources is higher than its availability, this work proposes the application of bankruptcy theories to design efficient Radio Resource Management policies that provide the highest possible quality of service levels while guaranteeing user fairness.

  • Common Radio Resource Management Algorithms for Multimedia Heterogeneous Wireless Networks
    IEEE Transactions on Mobile Computing, 2011
    Co-Authors: Miguel Lopez-benitez, Javier Gozalvez
    Abstract:

    Heterogeneous wireless systems are envisaged as the integration and joint cooperative Management of diverse Radio access networks and technologies through which network providers can satisfy the wide variety of user/service demands in a more efficient manner by exploiting their varying characteristics and properties. To achieve this objective, a key tool is common Radio Resource Management technique designed to jointly manage the Radio Resources from different Radio access technologies. In this context, this work proposes and optimizes new common Radio Resource Management techniques designed to efficiently distribute traffic among the available Radio access technologies while providing adequate quality of service levels under heterogeneous traffic scenarios. The obtained results demonstrate the ability of the proposed solutions to provide high user/service satisfaction levels while adequately exploiting the overall system Resources.

  • Wireless vehicular adaptive Radio Resource Management policies in congested channels
    Proceedings of 4th IEEE Internatilonal Symposium on Wireless Communication Systems 2007 ISWCS, 2007
    Co-Authors: Miguel Sepulcre, Javier Gozalvez
    Abstract:

    The strict QoS traffic safety requirements and the potential widespread adoption of wireless vehicular communication systems require the design and optimization of Radio Resource Management policies that efficiently use the communications channel. To this end, this work proposes an adaptive Radio Resource Management mechanism designed considering the operating conditions and the traffic safety requirements. The proposed scheme is analysed under various traffic densities, and compensation mechanisms to overcome the channel congestion effects are proposed and evaluated.
