A Novel Traffic Prediction Scheme for Broadband Satellite Communications System
نویسندگان
چکیده
Multi-user traffic prediction is an important issue in broadband satellite communications system. In view of multiple UTs (User Terminal) which are treated by a single ST (Satellite Terminal), a novel NMF-based (Nonnegative Matrix Factorization-based) multi-user traffic prediction method is proposed. Compared with previous prediction schemes, the new method can reduce computational complexity and remain comparable prediction accuracy. Simulation results based on real traffic data testify the validity of the proposed method. Streszczenie. Przedstawiono metodę prognozowania przesyłu danych w satelitarnym szerokopasmowym systemie komunikacyjnym. Nowa metoda traktuje każdego z wielu użytkowników sieci jako pojedynczy terminal satelitarny. (Nowa metoda prognozowania przepływu danych w szerokopasmowym satelitarnym systemie komunikacyjnym)

متن کاملA predictive demand assignment multiple access protocol for broadband satellite networks supporting Internet applications
To enhance the performance of broadband satellite networks, the application characteristics should be considered in the design of the medium access control (MAC) protocol. With the rapid expansion of Internet applications and the attractiveness of high speed Internet access via broadband satellite networks, it is important to take into account the selfsimilar nature of Internet traffic in MAC p...
متن کاملEstimation and Prediction - Based Connection Admission Control in Broadband Satellite Systems
ETRI Journal, Volume 22, Number 4, December 2000 We apply a “sliding-window” Maximum Likelihood (ML) estimator to estimate traffic parameters of On-Off source and develop a method for estimating stochastic predicted individual cell arrival rates. Based on these results, we propose a simple Connection Admission Control (CAC) scheme for delay sensitive services in broadband onboard packet switchi...
متن کاملSimulation Study for a Broadband Multimedia VSAT Network
We present a simulation approach for assessment of quality of service and bandwidth utilization for a meshed broadband VSAT system over a geostationary (GEO) satellite. The model includes a bent-pipe satellite with a number of broadband VSATs carrying multimedia traffic. A multi-frequency time division multiple access (MF-TDMA) is used with an integrated call admission control (CAC) and bandwid...
متن کاملIntegrated Connection Admission Control and Bandwidth on Demand Algorithm for a Broadband Satellite Network with Heterogeneous Traffic
There are many system proposals for satellitebased broadband communications that promise high capacity and ease of access. Many of these proposals require advanced switching technology and signal processing on-board the satellite(s). One solution is based on a geo-synchronous (GEO) satellite system equipped with on-board processing and on-board switching. An important feature of this system is ...
