PENGARUH INDOOR ENVIRONMENT PADA JARINGAN IEEE 802.11 TERHADAP QUALITY OF EXPERIENCE LAYANAN VIDEO CALL SKYPE DAN WHATSAPP
Daftar Isi:
- ABSTRAK Saat ini banyak tersedia aplikasi layanan video call yang dapat digunakan, diantaranya aplikasi Skype dan WhatsApp. Para pengguna layanan pasti akan memilih aplikasi yang memiliki layanan video call yang bagus terutama di dalam ruangan yang sering terkendala sinyal akibat dari pengaruh indoor environment. Penilaian yang digunakan untuk mengukur kualitas layanan video call diantaranya dapat dinilai dari parameter Quality of Service (QoS) dan Quality of Experience (QoE). Parameter Quality of Service (QoS) yang diteliti dalam penelitian ini adalah packet loss, dan throughput. Sedangkan parameter Quality of Experience (QoE) yang diteliti adalah video delay dan video quality. Penelitian ini fokus terhadap perbandingan kualitas video call Skype dan WhatsApp terhadap variasi signal strength dengan mencari jawaban dari pertanyaan berikut ini: 1) Bagaimana nilai Quality of Service (QoS) dan Quality of Experience (QoE) Skype dan Whatsapp terhadap perubahan signal strength? 2) Apa Penyebab Packet Loss pada proses transmisi video di dalam ruangan? Setelah dilakukan analisa data, hasilnya adalah aplikasi WhatsApp memiliki keunggulan dari sisi kestabilan mempertahankan nilai throughput, video quality dan video delay saat kondisi signal strength lemah. Sedangkan untuk packet loss, kedua aplikasi cenderung memiliki tren respon yang tidak mengikuti perubahan signal strength. Packet loss yang terjadi di dalam ruangan kemungkinan terpengaruh dari efek multipath fading dalam ruangan.

The rating indicators which used to measure the application service quality are Quality of Service (QoS) and Quality of Experience (QoE). Throughput and packet loss parameters are used to determine the Quality of Service rating, while video delay and video quality are used to determine the Quality of Experience rating. This paper focus on the comparison of video call quality for both Skype and WhatsApp to signal strength variations by finding the answer of the following questions: 1) How is the value of Quality of Service and Quality of Experience of both Skype and WhatsApp to signal strength variations? 2) What is the cause of video transmission packet loss in indoor environment? After analyzing the data, the result is that WhatsApp has an advantage of maintain the stability of throughput, video quality, dan video delay value in a weak signal strength than Skype. In the other side, packet loss seems to have a trend responses which showing erratic value in correlation to signal strength variations for both applications. It may caused by multipath fading effect in indoor environment. Keywords : Quality of Experience, Quality of Service, VideoCall, Skype, WhatsApp, throughput, packet loss, video delay, video quality
