The IEEE 802.11 standard for wireless local area networks (LANs) recommends carrier sense multiple access with collision avoidance (CSMA/CA) as the medium access control (MAC) protocol. The contention-based CSMA/CA access mechanism is sensitive to the traffic load whereas the assignment-based access mechanism used by wireless telephone networks is not. Heavy traffic load in wireless LANs causes significant degradation of network performance. Thus conventional handoff algorithms employed in wireless telephone networks are not applicable to wireless LANs. In this paper, after examining existing handoff algorithms for wireless communications, we propose a handoff algorithm for wireless LANs. This algorithm considers traffic load as an important factor for initiating handoff. In normal traffic load, signal strength measurements from various access points are used the same as conventional handoff algorithms. However, in heavy traffic load, the hysteresis margin and the absolute threshold of traffic load are taken into account. A simulation model is developed to study the performance of the proposed algorithm. Simulation results indicate that the proposed algorithm significantly reduces the call dropping probability. Moreover, the relationship between QoS parameters and handoff initiation criteria is analyzed. Analytical results show how handoff initiation criteria might be set in accordance with the quality of services requested by users.","PeriodicalId":412984,"journal":{"name":"1998 International Zurich Seminar on Broadband Communications.

The system provides a LAN environment and group communication services to the customers. The main system components are: the intelligent bridge circuit, called the low-end card (LEC), the center brouter (bridging router), and the management server. The LEC is set up in the subscriber's household and provides the popular Ethernet interface (10 Base-T). The leased circuits are connected between the LEC and the center brouter. The LEC and the brouter are controlled by the management server to function as the group communication system. The brouter, which has a multiplex subscriber-port interface, is required to accommodate a lot of customers cost effectively. This paper presents the system design of a large-capacity brouter having a SDH/SONET multiplex-port interface and its operation. The brouter can accommodate up to approximately 2700 subscribers. Ethernet packets are transferred through each subscriber channel between the LEC and the brouter using the HDLC protocol. A group communication mechanism based on packet filtering via the MAC addresses of PCs is presented. The Ethernet packets are filtered by the brouter to eliminate all packets except those from/to the same group members. The group management operation among the center brouter, the LEC, and the management server is discussed.","PeriodicalId":412984,"journal":{"name":"1998 International Zurich Seminar on Broadband Communications.
