Dol, H.S. (author), Blom, K.C.H. (author), van Riet, M.W.G. (author), van de Sande, J.J.M. (author)Stand-off mine countermeasure (MCM) operations with unmanned systems frequently require user involvement for the interpretation of image data, for classification and identification, and for decision-making during mine disposal. As the transfer of image data usually requires tethering, this leads to cumbersome operating procedures. We have...conference paper 2022

Singh, S. (author), Dijkstra-Soudarissanane, S. (author), Gunkel, S.N.B. (author)Currently, most videoconferencing technologies do not keep employees sufficiently engaged during business meetings. Recent studies have shown how extended reality (XR) technologies can help in executing remote meetings in new and possibly better ways. One important factor for meetings in e.g. Virtual Reality (VR) is avatar realism, with the...conference paper 2022

Keskin, R.S. (author), Pileggi, P. (author)The recent Cloud Monitor invention [1] aims to open actual insights, and give greater agency, to stakeholders in the Cloud ecosystem. But the varied nature and diverse user and provider needs, challenge the practicality of creating custom continuous cloud monitoring solutions using it. To accommodate customized needs at scale for dynamic systems...conference paper 2022

Wissingh, B. (author), Ravesteijn, D. (author), Schwartz, R.S. (author)This paper presents field trial results of two combined use cases with different QoS requirements: (1) a transport vertical Smart Junction use case; and (2) a healthcare vertical Paramedic Support use case. We focus on slicing prioritization configured in the RAN, at the gNB level, to guarantee QoS requirements for the combined use cases. We...conference paper 2022

Wetzels, F. (author), van den Berg, J.L. (author), van der Mei, R. (author)This paper is motivated by recent developments in SDN and NFV whereby service functions, distributed over a centralised controlled network, are connected to form a service function chain (SFC). Upon arrival of a new service request a decision has to be made to which one of SFCs the request must be routed. This decision is based on (1) actual...conference paper 2021

Dijkstra-Soudarissanane, S.S. (author), Klunder, T.E. (author), Brandt, A. (author), Niamut, O.A. (author)Due to the current pandemic, the elderly in care homes are greatly affected by the lack of contact with their families, resulting in various mental conditions (e.g., depression, feelings of loneliness) and deterioration of mental health for dementia patients. In response, residents and family members increasingly resorted to mediated...conference paper 2021

Raftopoulou, M. (author), Litjens, R. (author)Network slicing has been introduced in 5G networks as an enabling feature for the effective Quality of Service (QoS) provisioning to multiple service classes with distinct performance requirements. When applied in the Radio Access Network (RAN), a class-specific slice is assigned a set of radio resources and can furthermore be optimally...conference paper 2021

Gunkel, S.N.B. (author)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...conference paper 2019

(author)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...conference paper 2019

Blom, K.C.H. (author), Dol, H.S. (author)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...conference paper 2019

van der Sluis, F. (author), van den Broek, E.L. (author), van Drunen, A. (author), Beerends, J.G. (author)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...article 2018

(author)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...article 2015
