Abstract

We propose a new method to determine the optimal TXOP duration (TD) of scheduling algorithm for VBR traffics that guarantees delay and loss probability in IEEE 802.11e HCCA. In this algorithm, the TXOP Duration for each Traffic Stream (TS) is determined by the number (N) of packets to be transmitted during a TXOP duration, which is found by analyzing M/D N /1/N×l queueing system where the delay bound of the TS is l times the Service Interval having D length. Numerical results show that the number of admitted TSs with guaranteed loss probability by new method is greater than the number of admitted TSs by other known schemes.
