We report on the implementation of a software defined radio (SDR) based on state-of-theart digital signal processors (DSPs), which are linked serially to PCs. While time critical operations are executed on specialised transmit and receive processors with a fixed block structure, the baseband

slice of PlanetLab. This paper describes our initial implementation of PlanetLab, including the mechanisms used to implement virtualization, and the collection of core services used to manage PlanetLab. 1.

experimentation in a physical outdoor ad hoc networking testbed we have constructed in Pittsburgh, and have demonstrated the excellent performance of the protocol. In this chapter, we describe the design of DSR and provide a summary of some of our simulation and testbed implementation results for the protocol.

We present the results from over-the-air experiments of a complete implementation of an amplify and forward cooperative communications link. Our custom OFDM-based physical layer uses a distributed version of the Alamouti block code, where the relay sends one of the branches of Alamouti

Abstract—We present the implementation and experimental evaluation of a new, fully distributed protocol for random access systems that exploits symbol-level physical layer cooperation. By allowing single-antenna nodes to cooperate with their neighbors, MIMO-like performance is achieved. Our

synchronization attacks on some important sensor network applications, and explain the set of possible attacks on FTSP. We then propose a number of countermeasures to mitigate the effect of the security attacks. We implement these attack scenarios on a sensor network testbed. We show the extent each attack

with many more promising applications. In this pa-per, we propose a protocol for vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication. As one of the challenging parts of this paper, we present an experimen-tal testbed in which two major applications of V2I & V2V communication (i

Abstract—This paper presents the design and implementation of a novel SDR based massive MIMO testbed with up to 70 nodes built at Tennessee Technological University. The deployment can reach a 30×30 antenna MIMO scheme. With this testbed, we are able to measure the channel matrix and compute
