Broadband Wireless Access

Beschreibung

This chapter has discussed how a commonbroadcast medium can be shared among many contending users. Multiple access protocols differ primarily by the amount of coordination needed to control potentially conflicting packet transmissions. Ato neextreme is random access where no coordinationis provideda ndp acket collisions arep ossible. Atthe other endo fthe spectrum, the class of fixed assignment access protocols eliminates collisions entirely butpay the price ofadditional overhead required forscheduling user access. Hybrid access protocolsb etweenthese two extremes exist While these protocols attempt to combine the advantages ofrandom andfixed access, they also suffer the c ombined drawbacks and overhead ofboth classes of access schemes. Amongt he many factors that determine the performance ofa n access protocol include the propagation delay/packet transmission timeratio, the message arrival process, the types of feedback information available, the user population, and the abilityof the user to sense the activities in the network.
