A NEW INTEGRATED CONTROL ALGORITHM FOR IEEE 802.11G STANDARDS
Wi-Fi (Wireless Fidelity) mainly adopts IEEE 802.11g standards. And a binary exponential backoff algorithm is adopted to prevent channel collision, which also introduces reduction of the performance of the network. In this paper, an integrated control mechanism (ICM) is proposed which combines a centrally controlled approach and a distributed access mechanism to control the behavior of the system. Through this mechanism, backoff is eliminated from transmission mode, which can significantly enhance the performance of the system. Through theoretical analysis and simulation, the new mechanism can improve the throughput and reduce delay and packet loss rate. According to the results of simulation, with ICM, the throughput can have an improvement of 83.3％ and the packet loss rate remains at 0 under appropriate conditions.
