The paper discusses two implementation options for a Digital Video Library, a repository used for archiving, accessing, and browsing of video medical records. Two crucial issues to be decided on are a video compression format and a video streaming platform. The paper presents numerous decision factors that have to be taken into account. The compression(More)
Network virtualization is one of the key concepts of the Future Internet. However, the use of virtualization techniques in wireless mesh networks has thus far not been adequately studied. In this paper we describe ViMeNO: a Virtual wireless Mesh Network architecture for Operators, i.e., the first virtualization-enabled wireless mesh network architecture(More)
The paper presents a monitoring system for carrier grade mesh networks. First, the system architecture, components and interfaces are described. Then the measured and discovered network parameters are discussed. A link prediction and trigger algorithm based on a modified mean-reverting diffusion process is proposed. The results from analysis show that this(More)
Flexibility is an important paradigm for future WiFi networks. However, it also opens the possibility for diverse methods of cheating, which users can perform to increase their throughput. Therefore, it is important to develop the necessary tools to mitigate such efforts. In this paper we first discuss the risks of flexibility in terms of misbehaviour. We(More)
Even though current mesh networks are mostly WiFi-based, future networks are expected to be highly heterogeneous. Motivated by this expectation, CARMEN (CARrier grade MEsh Networks) project focuses on developing a heterogeneous mesh backhaul to provide carrier-grade (voice, video and data) services. This demo presents resource management and abstraction in(More)
