    ABSTRACT: We consider the design and implementation of the binary consensus algorithm in wireless sensor networks (WSN) under real life environment. This algorithm is applied for the evaluation of a consensus of a measured values in presence of a faulty/attacked node. As this algorithm has been tested theoretically, we deploy it for real-life environment including distributed and routing features. In this paper, we propose the development and the implementation of the distributed binary consensus algorithm in WSN under Tinyos environment. The implementation was tested on sensor nodes using the TinyOSSimulator for a WSN with a large number of nodes and a testbed with limited number of nodes. We evaluate the performances related to the average convergence time of nodes states to a consensus value. As in analytical results, in the simulations, we applied the distributed algorithm for fully connected, ring, cycle, Erdos Reny random, and star-shaped topologies.

    ABSTRACT: In this paper, we introduce the hardware implementation of video acquisition in a sensor node of wireless sensor network with the help of USB 2.0 interface. The USB 2.0 video acquisition is based on the CY7C67300 controller and the DCC1545M image sensor. In this paper, we detail the hardware architecture and the application program design in a sensor node using field-programmable gate array (FPGA) board and USB 2.0 interface. The CY7C67300 controller is the suitable choice for FPGA Virtex 4 and 5 based USB peripherals. A simple interface module capable of transferring data rates above 400 Mbits/s is implemented to communicate with the CY7C67300 controller. In order to use the developed module, in Xilinx embedded design, we provide a custom peripheral which includes the CY767300 interface as its core and additional logic for the connection to the external peripheral controller (EPC) and then the processor local bus (PLB). Index Terms—Embedded systems, FPGA, video acquisition, VHDL, wireless sensor network.

    ABSTRACT: 1 Stating the problem Large civil structures such as buildings and bridges form the backbone of our society and are critical to its daily operation. Inspectors typically assess them manually, but a networked computer system that could automatically assess structural integrity could measurably lengthen a structure's lifetime, reduce its operational cost and improve the overall public safety.
