| Summary: | 碩士 === 國立臺灣大學 === 電機工程學系研究所 === 86 === In the wake of the development of the communication technologies, the
applied range of the wireless communication has become wider and wider.
Facing the day-by-day complicated control scheme, we need to develop a set of
means to quickly predict the performance in order to enforce the advanced
control. In the environment of Wireless Integrated Services, the voice and
the data coexist and the demand for the Quality of Service (QoS) is also
different from the traditional environment. Besides the demand for the delay
mean, time-sensitive data also needs to monitor and control the delay jitter.
In order to present the burstiness of traffic, we will use a new type of
source to simulate the traffic situation.
At first, this paper analyzes the situation of single VBR traffic, and
use it as the basis of the further analysis. When we use the rest of voice
traffic, we have two totally different ways - complete sharing technique and
complete partitioning technique. After we calculate the results of these
ways, we can compare the differences between their performance. Finally, we
can use this model to get the predicted performance quickly and use it as
the basis of Usage Parameter Control (UPC) and Call Admission control (CAC).
