Connection admission control for PRMA/DA wireless access protocol
Jeong Geun Kim, Indra Widjaja · 2002
Next generation wireless communication systems will handle a wide range of services such as voice, video, and data. In this multi-service scenario, major technical issues are concerned with the selection of a suitable media access control (MAC) protocol and provision of adequate quality of service (QoS) to network users. We introduce a wireless media access control (MAC) protocol which is capable of transporting broadband traffic and providing seamless connectivity to ATM (asynchronous transfer mode) networks. Our protocol, having an air interface comparable to ATM, adopts a dynamic channel allocation scheme which enables expeditious network access and utilizes bandwidth resource efficiently for a mixed voice/video/data traffic environment. Simulation results presented here show the effectiveness of wireless access scheme, QoS provision, and dynamic channel allocation in terms of key performance metrics such as: throughput, cell loss-rate, call access delay, and cell transmission delay.
