Abstract: A network having distribution of access point loading includes access points to which mobile stations can associate themselves based upon access point beacon signal levels and loading levels for the various access points. A mobile station receives beacon signals from various access points and determines a signal strength for the received beacon signals. The mobile station also receives access point loading information from the access points. The mobile station associates with an access point based upon the access point beacon signal strengths and the access point loading information.

Abstract: A method for setting and adjusting MAC fragmentation threshold for IEEE 802.11 networks operating at different data rates is presented. The fragmentation threshold is adjusted based on throughput performance, delay constraints and hidden node influence.

Abstract: A network includes access points that admit/terminate mobile station associations based upon the loading level of the access point and/or whether a mobile station can associate with a further access point. Mobile stations transmit information indicative of the access points to which they can associate. The access points determine whether to admit/terminate a mobile station association based upon access point loading.

Abstract: A method of shaping data packet transmissions by nodes in a wireless network is presented. Each node sets a maximum limit for MAC service data unit size based on data rate so that maximum transmission times for data packet transmissions by all of the nodes are approximately the same.
