“…Berbeda dengan penelitian lain yang telah dilakukan, penelitian ini bertujuan untuk membandingkan model matematika untuk memprediksi ketersediaan bandwidth pada jaringan nirkabel. Selain itu, model yang digunakan adalah memiliki karakteristik pasif, yaitu dapat memprediksi ketersediaan bandwidth tanpa harus membebani jaringan internet yang digunakan [20]. Dengan kata lain, model yang digunakan berfungsi untuk memantau kondisi jaringan antarperangkat tanpa mengirimkan probing packets [21] [22].…”

ABSTRAKKetersediaan bandwidth merupakan salah satu aspek penting untuk menjamin QoS dalam transmisi data, terutama pada jaringan nirkabel. Walaupun demikian, prediksi ketersediaan pada jaringan nirkabel masih sulit dilakukan karena medium transmisi dapat digunakan oleh beberapa node secara bersamaan. Selain itu jaringan nirkabel juga rentan terhadap pengaruh dari sinyal transmisi yang dihasilkan dari node lain, terutama hidden node. Beberapa penelitian telah dilakukan untuk mengembangkan model prediksi ketersediaan bandwidth. Walaupun demikian, belum terdapat mekanisme terstandarisasi yang digunakan untuk mengevaluasi ketersediaan bandwidth pada jaringan nirkabel. Selain itu tingkat akurasi dari setiap model juga masih belum diketahui ketika diimplementasikan pada jaringan nirkabel, terutama dengan keberadaan hidden node. Oleh karena itu penelitian ini berupaya untuk menginvestigasi kinerja dari setiap model untuk memprediksi ketersediaan bandwidth pada jaringan nirkabel dengan interferensi hidden node. Model prediksi yang dibandingkan adalah Distributed ABSTRACT QoS requirement guarantee can be determined by some factors. But, one of the most critical factor is the availability of bandwidth, particularly in wireless networks because in real environment the transmission medium can be used by several devices or noes simultaneously. It causes the availability of bandwidth prediction tend to more difficult. In addition, wireless networks are also vulnerable to transmission signals generated from other nodes. Many researches have been conducted to build the availability of bandwidth prediction model. However, there is no standardized mechanism used to evaluate them on wireless networks. Moreover, the level of accuracy of each model is still unknown when implemented on wireless networks, particularly with hidden nodes interference as neighboring nodes. Hence, this research aims to evaluate the performance of each model to predict the availability of bandwidth on wireless network with hidden node interference. These models are Distributed Lagrange Interpolation Based Available Bandwidth Estimation (DLI-ABE), Cognitive Passive Estimation of the Available Bandwidth (cPEAB), Improved Available Bandwidth (IAB), and Available Bandwidth Estimation (ABE). The experiments were carried out on a simulation scale that was developed using OMNet++ network simulator. The result showed that ABE model obtained the best accuracy rate of 85.25%.

Sophisticated dynamic bandwidth allocation (DBA) algorithms can dramatically improve or worsen throughput and delay in whole networks. It is very important to choose the right DBA algorithm. Our work tests static assignment and three DBA algorithms, namely GigaPON Access Network DBA, Hybrid Reporting Allocation, and modified Max–Min Fair. All tests were made on our simulator of ten-gigabit passive optical network DBA specially developed for testing DBA algorithms. The tests verify delay of each optical network unit and amount of waste with bandwidth. This paper describes how the used DBA algorithms work and the processes involved in DBA algorithms.

The dis-aggregated passive optical network (PON) optical line terminal (OLT) architecture is attracting attention in academia and industry. This paper first reviews the evolution in dynamic bandwidth allocation (DBA) dis-aggregation. We further enhance the scalability of the dis-aggregated PON-OLT by reducing the bandwidth overhead of REPORT/GATE, the time division multiplexing (TDM) control information transferred between dis-aggregated DBA and the hardware platform. Our experiment verifies that the data compression based on basic integer coding can improve the scalability by 27% with acceptable processing time.
