A Weakly Synchronous and Distributed Coordination Function for QoS Management in CSMA/CA Wireless Access Networks

Moreover a signalling architecture is here designed, for the first time, to enable dynamic and distributed resource reservation over the wireless network by means of two protocols: the Resource Reservation Protocols with Traffic Engineering (RSVP-TE), properly extended to work in TD-uCSMA networks and the new Resource State Management Protocol (RSMP). The TD-uCSMA operating principles and the signalling architecture are then validated by simulation over many scenarios comprising multi-hop wireless access networks. Finally the chapter addresses the issue of prototyping TD-uCSMA by open source IEEE 802.11 legacy drivers.
