    • Spatial distribution analysis with capture effect of a mobile S-ALOHA network 

      Covarrubias, David; Ruiz Boqué, Sílvia; Huguet, Joan; Olmos Bonafé, Juan José (Institute of Electrical and Electronics Engineers (IEEE), 1998)
      Text en actes de congrés
      Accés obert
      The throughput performance of a mobile S-ALOHA network can be improved considering the capture phenomenon, which also depends on the spatial distribution of the mobiles within the cell. We have studied the capture probabilities ...
