This paper introduces TRACELAB, a new testbed architecture that allows for fine-grained tracing of time sensitive behavior of low-power wireless embedded systems. Such traces help to systematically analyze code execution to find software errors, measure bounds for execution times, or to verify functional program properties. TRACELAB builds on the idea of GPIO tracing: by including short GPIO instructions...
Wireless Sensor Networks (WSNs) are a key technology for future social and industrial developments. With increasingly complex applications, the compute demands for in-node / in-network processing have been growing steadily, while the capabilities of energy-harvesting or -storage systems have advanced only slowly. We present the Hardware-Accelerated Low Power Mote (HaLoMote), a heterogeneous system...
Increasing demand on wireless communications also increases the issues related to communication security. Among different security solutions, physical layer security have recently been gaining many interests by the researchers. In this paper, a survey study is provided in one of the most critical attacks, namely spoofing attacks. When a legitimate transmitter stops sending a signal to a legitimate...
Emerging Software Defined Networking (SDN) technology has provided excellent flexibility to large-scale networks in terms of control, management, security, and maintenance. With SDN, network architectures can be deployed and maintained with ease. New trends in computing (e.g., cloud computing, data centers, and virtualization) can seamlessly be integrated with the SDN architecture. On the other hand,...
Several traffic evaluation and congestion detection protocols have been proposed in the literature for the vehicular networks. These protocols gather and analyze the basic traffic data of all traveling vehicles at each area of interest to obtain the vehicular traffic evaluations. All vehicles should be equipped by wireless transceiver in order to send and receive the packets of their traffic data...
