Furthermore, an example application...
The main goal of this paper is to propose a simple and low-cost microcontroller-based laser communication link. To demonstrate that laser communication is a viable and efficient means for transmitting data, a transceiver capable of transfer rates of approximately 0.7 kB/s is prototyped. The hardware used for the transceiver consists of Commercial Off-The-Shelf (COTS) lasers, photodiodes, and the Arduino...
The Pulsar IIb is a general purpose FPGA-based processor board designed for full mesh ATCA backplanes. This hardware was originally designed to support Level-1 silicon track trigger R&D projects at the LHC. Each ATCA carrier board is required to support the Intelligent Platform Management Interface (IPMI) protocol, which is responsible for coordinating hot swap operations and for exchanging sensor...
The Internet of Things offers a growing market open to new products. To be able to take advantages of this opportunity companies need to be able to quickly create prototypes of their products.

This paper presents IDEA1, a validated SystemC-based simulator for WSNs. It allows the system-level performance evaluation (e.g., packet transmission and energy consumption) with elaborate models of sensor nodes. IDEA1 uses a clock-based synchronization mechanism to support simulations with cycle accurate communication and approximate time computation. Its accuracy has been validated by a testbed...
Wireless Sensor Networks consist of resource-constrained (energy, memory and processing) sensor nodes that are deployed at different locations, in order to monitor physical or environmental conditions. Several limitations exist nowadays, at simulation and at programming level, especially for heterogeneous Wireless Sensor Networks (composed of different hardware devices). Indeed, to optimize a self-organized...
