ANALISIS QOS VIDEO STREAMING JARINGAN WIRELESS: (STUDI KASUS: TAMAN INTERNET ENGKU PUTRI BATAM)

The increasing number of internet users in Indonesia has an impact on increasing the number of users of streaming video. The increase in the number of users is based on technological developments with the emergence of mobile devices such as notebooks, tablets and smartphones equipped with internet access via wireless networks. Unlike networks using cables, the characteristics of using video streaming over wireless networks are limited when compared to those using cables. To access various applications on the internet, including video streaming, a stable internet service is needed. For this reason, a Quality of Service (QoS) measurement research is needed which is carried out at one of the wireless network provider points in the city of Batam, namely Taman Internet Engku Putri. QoS can be used to measure and analyze the stability and quality of a wireless network. The parameters used in the measurement and analysis of QoS are Throughput, Delay, Jitter and Pakect Loss which will be tested on video streaming services. The test will be carried out at certain times such as peak hours and low hours. Low hours usually range from 08.00 WIB - 15.00 WIB and rush hour usually ranges from 15.00 WIB - 21.00 WIB. The results of measurement and analysis using four QoS parameters show that the video streaming service using wireless networks in Taman Internet Engku Putri is in the medium category

Saving Energy in Mobile Devices for On-Demand Multimedia Streaming -- A Cross-Layer Approach

This paper proposes a novel energy-efficient multimedia delivery system called EStreamer. First, we study the relationship between buffer size at the client, burst-shaped TCP-based multimedia traffic, and energy consumption of wireless network interfaces in smartphones. Based on the study, we design and implement EStreamer for constant bit rate and rate-adaptive streaming. EStreamer can improve battery lifetime by 3x, 1.5x and 2x while streaming over Wi-Fi, 3G and 4G respectively.Comment: Accepted in ACM Transactions on Multimedia Computing, Communications and Applications (ACM TOMCCAP), November 201

On Factors Affecting the Usage and Adoption of a Nation-wide TV Streaming Service

Using nine months of access logs comprising 1.9 Billion sessions to BBC iPlayer, we survey the UK ISP ecosystem to understand the factors affecting adoption and usage of a high bandwidth TV streaming application across different providers. We find evidence that connection speeds are important and that external events can have a huge impact for live TV usage. Then, through a temporal analysis of the access logs, we demonstrate that data usage caps imposed by mobile ISPs significantly affect usage patterns, and look for solutions. We show that product bundle discounts with a related fixed-line ISP, a strategy already employed by some mobile providers, can better support user needs and capture a bigger share of accesses. We observe that users regularly split their sessions between mobile and fixed-line connections, suggesting a straightforward strategy for offloading by speculatively pre-fetching content from a fixed-line ISP before access on mobile devices.Comment: In Proceedings of IEEE INFOCOM 201

Smart PIN: utility-based replication and delivery of multimedia content to mobile users in wireless networks

Next generation wireless networks rely on heterogeneous connectivity technologies to support various rich media services such as personal information storage, file sharing and multimedia streaming. Due to users’ mobility and dynamic characteristics of wireless networks, data availability in collaborating devices is a critical issue. In this context Smart PIN was proposed as a personal information network which focuses on performance of delivery and cost efficiency. Smart PIN uses a novel data replication scheme based on individual and overall system utility to best balance the requirements for static data and multimedia content delivery with variable device availability due to user mobility. Simulations show improved results in comparison with other general purpose data replication schemes in terms of data availability
