Abstract
In IEEE 80211 wireless LANs, hidden nodes can disrupt the backoff algorithm of other nodes that are located outside the physical carrier sensing range of hidden nodes. The fairness problem between the nodes that are vulnerable and not vulnerable to the hidden node problem is dealt with in this paper. We propose an efficient fair MAC protocol to resolve the fairness problem.
Abstract
Combining the IEEE 802.11 basic MAC (medium access control) protocols, which are the DCF (distributed coordination function) and the PCF (point coordination function), we propose a hybrid MAC protocol to improve the performance of IEEE 802.11 wireless LANs and mitigate the hidden node problem.
