Pijnappel, T.R. (author), van den Berg, J.L. (author), Borst, S.C. (author), Litjens, R. (author)Drone base stations can help safeguard coverage and provide capacity relief when cellular networks are under stress. Examples of such stress scenarios are events with massive crowds or network outages. In this paper we focus on a disaster scenario with emergence of a traffic hotspot, where agile drone positioning and load management is a...conference paper 2021

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

Post, B. (author), Borst, S. (author), van den Berg, J.L. (author)Due to the rising concerns of energy consumption in wireless networks, base station (BS) sleeping strategies were introduced to save energy in low traffic scenarios. In this paper we analyse a weighted trade-off between energy consumption and user-perceived performance in dense cellular networks. We present an optimization problem representing...article 2021

Wetzels, F. (author), van den Berg, J.L. (author), Bosman, J.W. (author), van der Mei, R. (author)In service function chaining, data flows from a particular application or user travel along a pre-defined sequence of network functions. Appropriate service function chaining resource allocation is required to comply with the service level required by the application. In this paper, we introduce a dynamic priority assignment for flows that...conference paper 2019

Post, B. (author), Borst, S. (author), van den Berg, J.L. (author)Network densification has emerged as a powerful paradigm to boost spectral efficiency and accommodate the continual rise in demand for wireless capacity. In dense cell deployments however, overlapping coverage areas may cause highly varying interference conditions among different cells. Moreover, denser networks experience more temporal load...conference paper 2019

Kleinrouweler, J.W.M. (author), Meixner, B. (author), Bosman, J.W. (author), van den Berg, J.L. (author), van der Mei, R. (author), Cesar, P. (author)Frequent variations in throughput make mobile networks a challenging environment for video streaming. Current video players deal with those variations by matching video quality to network throughput. However, this adaptation strategy results in frequent changes of video resolution and bitrate, which negatively impacts the users' streaming...conference paper 2018

(author)This paper deals with the problem of inferring short time-scale fluctuations of a system's behavior from periodic state measurements. In particular, we devise a novel, efficient procedure to compute four interesting performance metrics for a transient birth-death process on an interval of fixed length with given begin and end states: the...article 2015

Ellens, W. (author), Mandjes, M. (author), Worm, D.T.H. (author), van den Berg, J.L. (author)For effective capacity management in access networks, it is essential to have a good insight in the service quality perceived by the users. As users share the service capacity available, one would want to know how the achieved per-user throughput fluctuates over time. In this paper we present a novel method that assesses the per-user throughput...conference paper 2014

(author)This paper considers a class of queueing network models where nodes have to contend with each other to serve their customers. In each time slot, a node with a non-empty queue either serves a customer or is blocked by a node in its vicinity. The focus of our study is on analyzing the throughput and identifying bottleneck nodes in such networks....article 2013
