- Abstract
- In wireless personal area networks (WPANs), the successful design of channel time allocation algorithm is a key
factor in guaranteeing the various quality of service (QoS) requirements for the stringent real-time constraints of
multimedia services. In this paper we propose a channel time allocation algorithm for achieving a high quality
transmission and high channel error tolerance of MPEG stream in the IEEE 802.15.3 high-rate wireless PANs. Our
algorithm exploits the characteristics of MPEG stream. When a new MPEG stream arrives, a DEV models it by the
traffic envelope and delivers the traffic envelope to the piconet coordinator (PNC) along with the channel time request.
The PNC performs channel time allocation according to the envelope. Performance of the proposed scheme is investigated
by simulation and analysis. Our results show that compared to conventional scheme, the proposed scheme
is very effective and provides a good performance under typical channel error conditions.
