The IEEE 802.11 protocol inherently provides the same long-term throughput to all the clients associated with a given access point (AP). In this paper, we first identify a clever, low-power jamming attack that can take advantage of this behavioral trait: the placement of a low-power jammer in a way that it affects a single legitimate client can cause(More)
—Information-centric networking (ICN) has been touted as an alternative to the current Internet architecture by several research groups. So far little has been done towards the implementation of ICN network stacks and their evaluation in realistic ICN deployments. In this paper we describe Blackadder, a sophisticated prototype of our ICN architecture, and(More)
—Network coding has been proposed as a technique that can potentially increase the transport capacity of a wireless network via processing and mixing of data packets at intermediate routers. However, most previous studies either assume a fixed transmission rate or do not consider the impact of using diverse rates on the network coding gain. Since in many(More)
As experimentation becomes one of the de-facto approaches for benchmarking, researchers are turning to testbeds to test, review and verify their work. As a result, several research laboratories build wireless testbeds, in order to offer their researchers a real environment to test their algorithms. As testbeds become more and more popular, the need for a(More)
—The areas of Software-Defined Networking (SDN) and Information-Centric Networking (ICN) have gained increasing attention in the wider research community, while gaining credibility through corporate interest and investment. With the promise of SDN to simplify the deployment of alternative network architectures, the question arises how SDN and ICN could(More)
Hardware accelerators in networking systems for control algorithms offer a promising approach to scale performance. To that end, several research efforts have been devoted to verify a hardware version of complex control algorithms but only for small-scale hardware unit tests. In this paper we propose and evaluate an emulation framework, in which such(More)
Intersession network coding (NC) can provide significant performance benefits via mixing packets at wireless routers; these benefits are especially pronounced when NC is applied in conjunction with intelligent link scheduling. NC however imposes certain processing operations, such as encoding, decoding, copying and storage. When not utilized carefully, all(More)
The gradually growing need for testbed use so as networking algorithms to be validated in real environment, has given rise to optimal utilization of testbed resources. Towards this direction, we present a new management tool that is used for assessing channel quality information in wireless testbed deployments. NITOS Connectivity Tool retrieves data(More)
Information-Centric Networking (ICN) has increasingly been attracting attention by the research community. In ICN the center of attention becomes the information itself and not the endpoints as in today's IP networks. In this demonstration we present applications that we developed as proof of concepts for our ICN approach. A video streaming as well as a(More)
