Video traffic is widely expected to account for a large portion of the in future wireline and wireless networks, as multimedia applications are becoming increasingly popular. Consequently, performance evaluation networking architectures, protocols, mechanisms video becomes important. traces, which give sizes, deadlines, qualities individual frames sequence, have been emerging convenient characterizations studies. In this tutorial we an introduction use traces First brief overview digital its...
The performance evaluation of video transport mechanisms becomes increasingly important as encoded accounts for growing portions the network traffic. Compared to widely studied MPEG-4 video, recently adopted H.264 coding standards include novel mechanisms, such hierarchical B frame prediction structures and highly efficient quality scalable coding, that have implications transport. This tutorial introduces a trace-based methodology video. We first give an overview then present trace...
The network transport of 3-D video, which contains two views a video scene, poses significant challenges due to the increased data, compared conventional single-view video. Addressing these requires thorough understanding traffic and multiplexing characteristics different representation formats We examine average bitrate-distortion (RD) bitrate variability-distortion three main formats. Specifically, we compare multiview (MV) encoding, frame sequential (FS) representation, side-by-side (SBS)...
The scalable video coding (SVC) extension of the H.264/AVC standard provides two mechanisms, namely coarse grain scalability (CGS) and medium (MGS), for quality encoding, which varies fidelity (signal-to-noise ratio) encoded stream. As its SVC are expected to become widely adopted network transport video, it is important thoroughly study their traffic characteristics, including bit rate variability. In this paper, we report on a large-scale rate-distortion (RD) variability-distortion (VD)...
Falling is one of the most common accidents with potentially irreversible consequences, especially considering special groups, such as elderly or disabled. One approach to solve this issue would be an early detection falling event. Towards reaching goal fall detection, we have worked on distinguishing and monitoring some basic human activities walking running. Since plan implement system mostly for seniors disabled, simplicity usage becomes very important. We successfully implemented...
Communication networks and the systems they interconnect are going through a phase of tremendous change. The former agnostic delivery content between endpoints has given way to increasingly adding functionality beyond moving data. Softwarization technologies including network function virtualization (NFV) soft-ware-defined networking (SDN) key enablers that introduce computing into network. This revolution, especially for mobile communication networks, represents major paradigm shift away...
In the early 2020s, coronavirus pandemic brought notion of remotely connected care to general population across globe. Oftentimes, timely provisioning access and implementation affordable are drivers behind tele-healthcare initiatives. Tele-healthcare has already garnered significant momentum in research implementations years preceding worldwide challenge 2020, supported by emerging capabilities communication networks. The Tactile Internet (TI) with human-in-the-loop is one those...
The broad proliferation of mobile devices in recent years has drastically changed the means accessing World Wide Web. Describing a shift away from desktop computer era for content consumption, predictions indicate that main access web-based will come devices. Concurrently, manner presentation as well; web artifacts are allowing richer media and higher levels user interaction which is enabled by increasing speeds networks. This article provides an overview more than two high level page...
Contribution: Practical active learning stations (PALSs)-equipped classrooms function similar to prototypical (ALCs). They support student collaboration and pedagogies but at a fraction of the cost. Background: Active technology are revitalizing STEM education their use has led an increase in performance satisfaction with environment postsecondary settings. An obstacle increasing access ALCs is cost constructing such environments. To address this challenge, means retrofit existing computer...
Mobile clouds embody a concept where mobile and wireless networks naturally embrace social in practical efficient fashion. In addition to enhancing communications performance improving the efficiency radio resource utilization, are flexible platform for sharing distributed resources of devices. We explore how physical nonmaterial can be shared by networks. Shareable residing devices considered primarily, but is extended encompass universal resources. Finally, we shed some light on converged...
The future Metaverse has been proposed as a solution to various social problems, requiring new concepts. This evolution of the will be geared toward solving real-world tasks by combining humans and machines in virtual real spaces. This, turn, necessitates inclusion additional human senses, including tactile modality, enable fully immersive human-machine human-machine-human cooperation. resulting challenges communicating ultra-low latency information below 1 ms threshold have guided Tactile...
The networked multimedia application, which has the increasing popularity of video data, is expected to account for a large portion traffic in Internet future and next-generation wireless systems. This article introduces traces gives sizes individual frames sequence also outlines how they characterize encoded can be used evaluating networking mechanisms.

In this work, we present a scheme based on Bluetooth friendly device names to enable power-optimized ad-hoc localization of mobile devices. Eliminating the service discovery and connection (including potential pairing) phases in allows for speedier more power-efficient conveying location information using names. Furthermore, observe that signal strength commonly provided reference APIs OSs, client distances can be calculated with high accuracy without additional power penalties.
While 5G mobile communication systems are currently in deployment, researchers around the world have already started to discuss 6G technology and funding agencies their first programs with a label. Although it may seem like good idea from historical point of view returning generations every decade, this contribution will show that there is great risk introducing labels at time. reasons not talk about yet manifold, some more dominant ones i.) exists lack real advancements introduced by...
