ABSTRAKSI: HSDPA merupakan UMTS Release 5 yang diperkenalkan oleh badan Standarisasi 3G di Eropa 3rd Generation Parnership Project (3GPP) yaitu skema baru dalam pengiriman data file yang dimana kecepatan downlink data rate mencapai 14,4 Mbps.Kecepatan downlink yang dimiliki oleh teknologi HSDPA ini sangat mendukung dalam transmisi berbagai data file terutama file multimedia seperti video streaming.
Pada tugas akhir ini dilakukan analisis terhadap jaringan HSDPA pada bagian layer MAC-hs yaitu dengan menganalisis hasil dari performansi dari file video dengan menggunakan dua metode scheduling, diantaranya Round Robin Scheduling dan Proportional Fair Scheduling. kedua scheduling ini akan diuji terhadap dua scenario yang telah dibuat, yaitu pengaruh terhadap penambahan file web dalam transmisi data dan kedua mengamati pengaruh terhadap penambahan jumlah user. skenario dimodelkan dengan menggunakan NS2 yaitu ns-allinone-2.26 dengan menambahkan modul EURANE (Enhanced UMTS Radio Access Network Extension) dan melakukan tambahan modifikasi scheduling Proportional Fair Scheduling.
dari hasil simulasi yang dihasilkan, kedua algoritma scheduling yang digunakan menghasilkan performansi yang berbeda, dari parameter yang ditetapkan yaitu delay, throughput, jitter dan packet loss. delay dan jitter yang dihasilkan oleh Proportional Fair Scheduling lebih baik dibandingkan dengan Round Robin Scheduling, begitu pula throughput menghasilkan nilai yang lebih baik walau dengan penambahan user. disisi lain packet loss yang dihasilkan dari kedua scheduling begitu besar nilainya walaupun memiliki perbedaan dari hasil nilai, hal ini dikarenakan file yang ditrasmisikan berupa video. namun dengan demikian dari keseluruhan scenario nilai delay, jitter, throughput dan packet loss tertinggi dicapai oleh Proportional Fair Scheduling.Kata Kunci : HSDPA, Round Robin Scheduling, Proportional Fair Scheduling, Video Streaming, delay, jitter, throughput, packet lossABSTRACT: HSDPA is UMTS Release 5 which was introduced by 3G Standardization Agency in Europe 3rd Generation Partnership Project (3GPP) as a new schematic in sending packet data which has a downlink data rate speed up to 14.4 Mbps. The downlink speed owned by the HSDPA technology is very supportive in every packet data transmission, particularly multimedia packet like video streaming.
In this final task, analysis is conducted for HSDPA network on MAC-hs layer by analyzing the result from video packet performance, using two scheduling method, such as Round Robin Scheduling and Proportional Fair Scheduling. These two scheduling will be tested in two scenarios. First the influence from web packet addition in data transmission. Second, observing the influence from additional number of users. The scnearios is modelled by using NS2, that is ns-allinone-2.26 by adding the Enhanced UMTS Radio Acces Network Extension (EURANE) module and by adding modification in Proportional Fair Scheduling.
From the simulation result, the two scheduling algorithm which used to create a different performance from the stated parameters, that is delay, throughput, jitter and packet loss. Delay and jitter which resulted from Proportional Fair Scheduling is better than the delay and jitter from Round Robin Scheduling, as well as throughput which results a better value even with the additional number of users. On the other hand, packet loss from these two scheduling has a big value even though they have different result. This is happened because of the transmitted packet is a video. But from the overall scenarios, the highest value of delay, jitter, throughput and packet loss achieved by Proportional Fair Scheduling.Keyword: HSDPA, Round Robin Scheduling, Proportional Fair Scheduling, Video Streaming, delay, jitter, throughput, packet loss
