中文摘要 | 本文探討兩種多頻道媒體存取取通信協定於行動電話網路系統:MPRMA,其為多頻道PRMA通信協定;MSAC,其為使用槽構式ALOHA控制頻道的多頻道通信協定。在固定的總頻寬中,對於整合服務以及不同服務品質,在成功送出資訊封包,可以預定下個傳送聲音封包資料的時間溝槽。本文利用Semi-Markov數學模式分析、比較,並經程式電腦模這兩種多頻道媒體存取取通信協定行動電話網路系統。其中,在固定的使用者的環境,我們改變頻變的數目、資訊封包的大小,以及控制封包溝槽的數目,求得封包被迫放棄的機率。 |
英文摘要 | Two multichannel media access protocols with different frequency channels for mobile cellular environment are investigated. MPRMA is a multichannel PRMA protocol and MSAC is a multichannel protocol with slotted ALOHA based control channel. Fixed total bandwidth is used. For integrated services and the different quality of services, only the voice packet can reserve the future slot during talkspurt when the information packet is transmitted successfully. For an analysis of the models, the Semi-Markov model was used. This Semi-Markov model has an advantage over the normal Markov model since it has the arbitrary sojourn time in the states. The comparisons of these protocols are investigated through the analytic model as well as the discrete-event simulation in terms of the number of simultaneous users, packet dropping probability with a variation of channel numbers, information packet size and the number of control packet slot. |
