  • This paper proposes a novel optimal control algorithm for multimedia traffc in IEEE 802.11eWLAN (Wireless LAN) and describes its control processbased on Markov process. In this algorithm, an optimization policy is utilized to assign idle channel for traffcswith different priority. The simulation results indicate thatthe proposed algorithm decreases the overhead caused bycollision detection and retransmission mechanism. Moreover, both access effciency and overall performance areenhanced remarkably, and wireless resource can also beemployed more effectively in the novel algorithm comparedwith PCF (Point coordination function).
