The maximum throughput is limited by the slowest transmitting station in IEEE 802.11 distributed coordination function (DCF) medium access control (MAC), giving rise to the rate anomaly problem. This limitation is carried into a cognitive IEEE 802.11b DCF MAC. In our paper, we propose airtime fairness in a cognitive rate separation IEEE 802.11b MAC. Stations are grouped according to their transmission...
IEEE 802.11 distributed coordination function (DCF) medium access control (MAC) does not provide airtime fairness for all stations in a multi-rate scenario as it only provides max-min throughput fairness. This gives rise to the rate anomaly problem where the maximum throughput is limited by the slowest transmitting station. In our paper, we propose airtime fairness in a rate separation IEEE 802.11b...
IEEE 802.11 protocol is widely used in Wireless Local Area Networks (WLAN) for its high data transmission rates. The formation flying satellite system has a short inter-satellite distance, which is similar to WLAN. It may be a good choice to apply IEEE 802.11 protocol in inter-satellite communication to increase throughput. However inter-satellite distance is longer than what desired by WLAN, so IEEE...
In conventional IEEE 802.11 medium access control protocol, the distributed coordination function is designed for the wireless stations (WSs) to perform channel contention within the wireless local area networks (WLANs). Packet collision is considered one of the major issues within this type of contention-based scheme, which can severely degrade the network performance for the WLANs. Research work...
The hidden receiver problem is the primary concern in mobile ad hoc networks (MANET), due to the high rates of neglecting the state of the hidden terminal; the potential sender (neighbors of the hidden terminal) enters into an unnecessary backoff process and retransmission circle, therefore leading to serious unfairness between contention terminals. Hidden receiver problem increases the probability...
