Mobility management in a wireless ATM LAN

Abstract

This paper presents the mobility management and connection control aspects of a wireless ATM LAN. This is part of an ongoing research project to explore various aspects of wireless ATM networking to support multimedia PCS applications. The LAN combines positive aspects of connection-oriented and datagram communication schemes in its usage of the ATM VP/VC concept. In-sequence cell delivery and QoS guarantees are provided for on-demand connections without requiring any node-by-node configuration at the transit nodes. We describe the mobility management procedures of mobile tracking, mobile location, and active handoffs. We also describe the algorithms used to admit connections with or without QoS checking.
