Joint Channel State Based Random Access and Adaptive Modulation in Wireless LAN with Multi-Packet Reception

—Conventional 802.11 medium access control (MAC) characteristics. In particular, all of these designs adopted a protocols have been designed separately from the characteristics simplistic collision model, which only supports one of the physical layer so as to simplify the analysis, but this hardly simultaneous transmission. Nevertheless, with advanced optimizes the overall performance from a system point of view. techniques of signal processing, multi-packet reception (MPR) In this paper, we propose a channel state based random access has become a feasible solution in practical systems [7], and this protocol that takes advantage of multi-packet reception (MPR) in brings new challenges as well as opportunities for the MAC IEEE 802.11-like wireless local area networks (WLANs). design. The MPR model was introduced by Ghez et al. [8, 9], Specifically, the proposed MAC protocol dynamically adjusts and recently, random access protocols that are based on such each node’s transmission prob...
