In this paper, authors presented a price maximization scheme for optimal orthogonal frequency division for multiple access (OFDMA) subcarrier allocation for wireless video unicast/multicast scenarios. They formulate a pricing based video utility function ... see more

In this paper, a two-dimensional (2D) rate model is proposed considering the joint impact of spatial (i.e., the frame size) and SNR (i.e., the quantization step) resolutions on the overall rate-distortion performance. A related 2D quality model is then pr... see more

Teknologi wireless mesh network (WMN) yang beroperasi pada standar IEEE 802.11 merupakan teknologi jaringan nirkabel terdiri dari mesh router dan mesh client dipadukan dengan internet, teknologi seluler dan jaringan sensor. Seiring perkembangan teknologi ... see more

The challenging of assessing formal and informal online learning at scale includes various issues. Many universities who are now promoting “Massive Online Open Courses” (MOOC), for instance, focus on relatively informal assessment of participant competenc... see more

This paper describes a three-screen television system using a block recovery rate (BRR)-based unequal error protection (UEP). The proposed in-home wireless network uses scalable video coding (SVC) and UEP with forward error correction (FEC) for maximizing... see more

The paper proposed the research on rural online distance education (RODE) based on the Beijing rural network condition, which aimed at helping farmers to get agricultural technology more effectively and sufficiently. This is the first platform that was ... see more

This paper aims to analyze Internet-based streaming video service in the communication media with variable bit rates. The proposed scheme on Dynamic Adaptive Streaming over HTTP (DASH) using the internet network that adapts to the protocol Hyper Text Tran... see more

The recent and rapid development of mobile devices and the increasing popularity of e learning have created a demand for mobile learning packages and environments. We have analyzed the possibilities of adapting the existing content for mobile devices, and... see more
