Virtual Reality (VR) applications are currently suffering several gaps to allow a full breakthrough in the consumer market. One aspect is the social isolation. Many VR experiences do not represent yourself or other users, making it lonely rather than a shared experience. VR applications that do offer a user representation mostly use artificial...

In this paper, we describe a user study in which pairs of users watch a video trailer and interact with each other, using two social Virtual Reality (sVR) systems, as well as in a face-to-face condition. The sVR systems are: Facebook Spaces, based on puppet-like customized avatars, and a video-based sVR system using photo-realistic virtual user...

For enabling efficient operation of untethered underwater vehicles, error-free underwater communication of command-and-control and telemetry data is a necessity. In contrast, the communication requirements for the sensor data of these vehicles are often less stringent, i.e., a few bad pixels in a SONAR image might be tolerated. To maximize...

5G promises to offer a single network platform that can be optimized for several vertical industries and applications. It is envisioned that this optimization will be achieved through advanced network orchestration functionalities. Video streaming accounts for the vast majority of mobile traffic, hence optimizing performance and Quality of...

Bandwidth is still a limiting factor for the Quality of Service (QoS) of mobile communication applications. In particular, for Voice over IP the QoS is not yet as good as for common, well-engineered, public-switched telephone networks. Multisensory communication has been identified as a possibility to moderate this limitation. One of the...

The chapter summarizes activities of COST IC1304 ACROSS European Project corresponding to traffic management for Cloud Federation (CF). In particular, we provide a survey of CF architectures and standardization activities. We present comprehensive multi-level model for traffic management in CF that consists of five levels: Level 5 - Strategies...

We present Wi-5, a spectrum programming architecture for radio resource management in unlicensed frequency bands. It introduces a spectrum control plane that offers fine grained allocation of radio resources, flexible configuration of radio and wireless networking parameters, and continuous monitoring of the wireless network status. These...

Available bandwidth is still a limiting factor for mobile communication applications. Multisensory communication has already been identified as an possibility to moderate this limitation. One of the strengths of mobile communication lies in its combination of visual and auditory modalities. However, one of the most salient features of mobile...

The continuing growth in the mobile phone arena, particularly in terms of device capabilities and ownership, is having a transformational impact on media consumption. It is now possible to consider orchestrated multistream experiences delivered across many devices, rather than the playback of content from a single device. However, there are...

There is a growing interest in the use of untethered underwater vehicles. These vehicles require robust and error-free underwater communication for transmission of mission-critical data. In contrast, the requirements for sensor payloads are often less stringent. Depending on the type of data, different Quality-ofService (QoS) demands can be...

The work presented here seeks an integration of spatial and social features supporting shared activities, and engages users in multiple locations to manipulate realtime video-streams. Standard and easily available equipment is used together with the communication standard WebRTC. It adds a spatial quality of experience by representing the users...

Mobile network operators (MNOs) are deploying carrier-grade Wireless Local Area Network (WLAN) as an important complementary system to cellular networks. Access network selection (ANS) between cellular and WLAN is an essential component to improve network performance and user quality-of-service (QoS) via controlled loading of these systems. In...

Link dimensioning is used by network operators to properly provision the capacity of their network links. Proposed methods for link dimensioning often require statistics, such as traffic variance, that need to be calculated from packet-level measurements. In practice, due to increasing traffic volume, operators deploy packet sampling techniques...

Service orchestration has become the predominant paradigm that enables businesses to combine and integrate services offered by third parties. For the commercial viability of orchestrated services, it is crucial that they are offered at sharp price-quality ratios. A complicating factor is that many attractive third-party services often show...

Node mobility is a key feature of using Wireless Sensor Networks (WSNs) in many sensory applications, such as healthcare. The Medium Access Control (MAC) protocol should properly support the mobility in the network. In particular, mobility is complicated for contention-free protocols like Time Division Multiple Access (TDMA). An efficient access...

Mobile network operators are currently preparing the introduction of QoS differentiation mechanisms in their 3G networks, as a means to support service-specific quality requirements, to enable the offering of distinct subscription forms and/or to enhance the resource efficiency and hence network capacity. In this paper we quantify the attainable...

Sensor nodes in many Wireless Body Area Network (WBAN) architectures are supposed to deliver sensed data to a gateway node on the body. To satisfy the data delivery requirements, the network needs to adapt itself to the changes in connection status of the body nodes to the gateway. As a prerequisite, Link Quality Estimation (LQE) needs to be...
