    • Analysis and evaluation of decentralized multiaccess Mac for ad-hoc networks 

      Pérez Neira, Ana Isabel; Realp, Marc (2003)
      Text en actes de congrés
      Accés obert
      In mobile ad-hoc radio networks, terminals are mobile and heterogeneous, the architecture of the network is continuously changing, communication links are packet oriented and radio resources are scarce. Therefore, ...

    • Decentralised multi-access MAC protocol for ad-hoc networks 

      Realp, Marc; Pérez Neira, Ana Isabel (2003)
      Text en actes de congrés
      Accés obert
      In ad-hoc radio networks, mechanisms on how to access the radio channel are extremely important in order to improve network efficiency and, when needed, to guarantee QoS. Traditionally, Medium Access Control (MAC) protocols ...

    • Delay bunds for resource allocation in wideband wireless systems 

      Pérez Neira, Ana Isabel; Realp, Marc; Knopp, Raymond (2006)
      Text en actes de congrés
      Accés obert
      In this paper, the problem of resource allocation in multiuser single-antenna wideband OFDM(A) systems is considered from a cross-layer point of view. The main motivation is to show advantages of such systems with respect ...

    • LAMAN: Load adaptable MAC for ad-hoc networks 

      Pérez Neira, Ana Isabel; Realp, Marc (2005)
      Article
      Accés restringit per política de l'editorial
      In mobile ad hoc radio networks, mechanisms on how to access the radio channel are extremely important in order to improve network efficiency. In this paper, the load adaptable medium access control for ad hoc networks ...

    • PHY-MAC dialogue with multi-packet reception 

      Pérez Neira, Ana Isabel; Realp, Marc (2001)
      Text en actes de congrés
      Accés obert
      Cross-layer design has been considered recently as a new approach when designing MAC protocols in systems with diversity such as CDMA. This paper goes one step further in the cross layer design by proposing a PHY-MAC ...

    • Throughput gains of space-times scheduling with no CSI 

      Realp, Marc; Pérez Neira, Ana Isabel (2007)
      Text en actes de congrés
      Accés obert
      Traditional works rely on the use of complete Channel State Information (CSI) at the base station to take space-time scheduling decisions in the uplink of multi-user MIMO wireless systems. However, this might be a complex ...
