    One of the promising applications of IEEE 802.16 (WiMAX)-based wireless mesh/relay networks is to provide infrastructure/backhaul support for IEEE 802.11-based mobile hotspots. In this article we present an architecture for integrating IEEE 802.11 WLANs with IEEE 802.16-based multihop wireless mesh infrastructure to relay WLAN traffic to the Internet. The major research issues in this integrated architecture are outlined and related work is reviewed. A game-theoretic model is developed for radio resource management in this integrated network architecture. In particular, a multiplayer bargaining game formulation is used for fair bandwidth allocation and optimal admission control of different types of connections (e.g., WLAN connections, relay connections, and connections from standalone subscriber stations) in an IEEE 802.16 base station/mesh router. Both connection-level and inconnection-level performances for this bandwidth management and admission control framework are presented View full abstract»

  • Sensor Localization under Limited Measurement Capabilities

    In this article we survey the latest progress on sensor localization, focusing on distance measurement techniques and localization algorithms for a sensor to determine its own location. We illustrate why inaccurate distance measurements, arising from tight hardware design constraints, raise challenges in sensor localization and how proposed approaches strive to overcome these challenges. We conclude that sensor localization algorithms must be designed to accommodate different application requirements in terms of costs, energy consumption, and localization accuracy View full abstract»

    In this work multiplexing of variable-rate sources over shared generic multiple fading channels is addressed. In general, the performance of existing multiplexing algorithms has been compared in very specific environments, making it difficult to draw general conclusions. In this article we propose a generic variable-rate multiuser and multichannel system model that can be applied to any orthogonal channel multiplexing mechanism (e.g., TDM, OFDM, CDM, or SDM) through parametric modeling. Based on the model, the performance of different multiplexing algorithms proposed in the literature is evaluated over moderately fast fading snared channels. Physical channel conditions, random traffic arrival, and QoS requirements are taken into consideration in the study. Multiuser capacity and fairness are assessed and evaluated for different channel-aware and/or QoS-aware user multiplexing algorithms. Results show the joint diversity gain and QoS in terms of the throughput and delay experienced by different user information flows View full abstract»

    Multihoming technology can be traced back to the 1980s or even earlier, but it seldom drew much attention from the research community. Recently, with the explosive deployment of multihoming on the Internet, researchers have started to investigate the issues that were raised by multihoming networks. This article draws an overall picture of multihoming technology, presents current research on multihoming networks, and discusses the issues that must be studied in the future View full abstract»

    The Internet has grown dramatically and evolved significantly over the past 10 years. Although this growth provides new opportunities and many value-added services for millions of Internet users, this growth also presents ongoing challenges to networking researchers, for whom the study of the Internet itself is the raison d'etre. Other than the network link speed, there are many technical challenges that make the monitoring of Internet applications difficult. To illustrate this point, this article presents several practical examples drawn from our experiences in Internet application measurement and monitoring View full abstract»
