Abstract
This paper presents a traversed path tracking based technique for
integrated
mobility and quality of service (QoS) management of connections in cellular
wireless
ATM networks. Simulation and analytical results for probabilities of
connection
Blocking, Dropping and Unsuccessful Connections are determined. A distributed
operating system based architecture for implementation of integrated
mobility and
QoS control is then proposed. The objective is to treat mobility as a network
impairment triggered activity which is to be handled via QoS management.
Depending on the speed of the mobile unit and the category of service being
used,
the QoS of a connection may or may not vary continuously during a session.
The
results presented here consider coexistence of constant bitrate (CBR) and
non-real-time variable bitrate (nrt-VBR) type ATM connections over a single
session.
