Abstract:

A Markov chain analysis model is presented to analyze bandwidth request scheme for besteffort and nonreal time polling services in pointtomultipoint mode of IEEE 80216 networks . The average delay of bandwidth request is evaluated by the contention window size, the number of contending subscriber stations(SSs), the number of slots allocated for bandwidth request and the maximum number of retransmission under saturated conditions. Simulations validate its high accuracy under different parameters and the number of SSs. 
