TL;DR: This paper quantifies network behavioral differences between simulations and real-world testbed experiments and finds that in the PHY layer, the distribution of received signal strength in experiments is usually different from simulation due to the antenna diversity, and in the network layer, a few dominant routes exist in test bed experiments while routes in simulations are less stable.
Abstract: Wireless simulators provide full control to researchers in investigating traffic flow behavior, but do not always reflect real-world scenarios. Although previous work pointed out such shortages are due to the limitation of radio propagation models in the simulators, it is still unclear how these imperfect models affect network behavior and to what degree. In this paper, we quantify network behavioral differences between simulations and real-world testbed experiments. We compare and analyze the experimental results from indoor and outdoor experiments with the results from NS-2 and Qualnet simulations. We find that in the PHY layer, the distribution of received signal strength in experiments is usually different from simulation due to the antenna diversity. However, path loss, which is regarded as a dominating factor in simulator channel modeling, can be configured to match the real-world behavior. For the MAC layer, increasing traffic load on a flow may cause significant performance degradation in experiments, but it is not the case in simulations. Interference is inadequately captured in simulations and cannot show the flow level unfairness phenomenon. In the network layer, a few dominant routes exist in testbed experiments while routes in simulations are less stable. These findings give the wireless research community an improved overview about the differences between simulations and testbed experiments. They will help researchers to choose between simulations and experiments according to their particular research requirements.

TL;DR: This project has designed and implemented a set of distributed autonomous home control agents and deployed them in a simulated home environment and their focus is primarily on resource coordination.
Abstract: Intelligent environments are an interesting development and research application problem for multi-agent systems. The functional and spatial distribution of tasks naturally lends itself to a multi-agent model and the existence of shared resources creates interactions over which the agents must coordinate. In the UMASS Intelligent Home project we have designed and implemented a set of distributed autonomous home control agents and deployed them in a simulated home environment. Our focus is primarily on resource coordination, though this project has multiple goals and areas of exploration ranging from the intellectual evaluation of the application as a general MAS testbed to the practical evaluation of our agent building and simulation tools.

TL;DR: An overview of the FMA infrastructure and hardware, which includes a fleet of quadrocopters and a motion capture system for vehicle localization, is shown.
Abstract: The Flying Machine Arena (FMA) is an indoor research space built specifically for the study of autonomous systems and aerial robotics. In this video, we give an overview of this testbed and some of its capabilities. We show the FMA infrastructure and hardware, which includes a fleet of quadrocopters and a motion capture system for vehicle localization. The physical components of the FMA are complemented by specialized software tools and components that facilitate the use of the space and provide a unified framework for communication and control. The flexibility and modularity of the experimental platform is highlighted by various research projects and demonstrations.

TL;DR: ADRENALINTE testbed is presented, an SDN/NFV packet/optical transport network and edge/core cloud platform for end-to-end 5G and IoT services.
Abstract: The fifth generation of mobile networks (5G) and the internet of Things (IoT) impose very stringent requirements to the optical transport networks. On the one hand, high flexibility, ultra-low latency and high capacity, in order to support the forecasted 1000x growth in mobile data traffic with latencies below millisecond. On the other hand, massive edge and core cloud infrastructure integrated with the transport network to dynamically deploy NFV, MEC, and IoT analytics. This paper presents ADRENALINTE testbed, an SDN/NFV packet/optical transport network and edge/core cloud platform for end-to-end 5G and IoT services.

TL;DR: This paper introduces X60, the first SDR-based testbed for 60 GHz WLANs, featuring fully programmable MAC/PHY/Network layers, multi-Gbps rates, and a user-configurable 12-element phased antenna array, and conducts an extensive measurement study, looking at different aspects of indoor 60 GHz links.
Abstract: This paper introduces X60, the first SDR-based testbed for 60 GHz WLANs, featuring fully programmable MAC/PHY/Network layers, multi-Gbps rates, and a user-configurable 12-element phased antenna array. Combined these features provide an unprecedented opportunity to re-examine the most important aspects of signal propagation and performance expected from practical 60 GHz systems. Leveraging the testbed's capabilities, we conduct an extensive measurement study, looking at different aspects of indoor 60 GHz links. We find that the presence of reflective surfaces and imperfect beams generated by practical phased arrays together can result in multiple NLoS paths supporting Gbps rates. Additionally, our comparison of different beam adaptation strategies reveals how beam steering even at one end of the link can often be sufficient to restore link quality.
