This paper focuses on the design and the performance evaluation of a new mech- anism, named Distributed Contention Control (DCC) , for the adaptive contention reduction in LAN networks that utilize random access MAC protocols. The pro- posed mechanism could be executed on the top of a pre-existent access protocol, with no additional overhead introduced. Specifically, we co nsider the IEEE 802.11 wireless LAN (WLAN). The DCC mechanism requires a simple andrough estimate of the contention level, and this can be achieved by estimating any parameter, di- rectly connected with the amount of contention on the shared channel. The main characteristics of the proposed mechanism are represented by its simplicity, inte- gration with the Standard, complete distribution, absence of overheads, and prompt reaction to changes in the network congestion. The protocol automatically adapts to the network congestion, by monitoring the channel contention level, through the estimation of the contention parameter. In the paper we show that the informa- tion needed for the contention estimation is already availa ble to a 802.11 station, with no additional costs. Simulation experiments to evaluate the performance of an IEEE 802.11 WLAN, with and without the DCC mechanism, havebeen carried out. Results confirmed the effectiveness of the DCC mechanis m in improving the performance, stability, and congestion reaction of the IEE E 802.11 access scheme. The DCC mechanism also provides a simple way to implement a distributed priority mechanism. |
