The main contribution of this paper is the implementation and experimental evaluation of thee radio power control algorithms for wireless sensor networks. We illustrate the necessity of lightweight radio power control algorithms for the deployment of wireless sensor networks in realistic situations. Furthermore, based on a simple loss model, we develop an algorithm that optimizes the transmit power while guaranteeing a desired packet error probability. The simple power control strategy is also compared with two other strategies in experiments using Tmote Sky sensor nodes. A component-based software implementation in the Contiki operating system is used.

This article describes a technique that allows a photovoltaic (PV) production unit to obtain the maximum power at all times. Here, we use the MPPT control via fuzzy logic on a DC/DC boost-type converter. In order to achieve our goals, we first proceeded to model a PV panel. The resulting model offers the possibility to better account for the influence of different physical quantities such as temperature, irradiation, series resistance, shunt resistance and diode saturation current. Thus, the maximum power to be provided by the PV system is acquired by fuzzification and defuzzification of the input and output variables of the converter. Subsequently, a virtual model of an 800 Watt PV prototype is implemented in the Matlab environment. The simulation results obtained and presented, show the feasibility and efficiency of the proposed technology. Indeed, for a disturbance caused by a variation in brightness, our system guarantees the maximum stable power after 1.4s. While for a load variation, the maximum power is continuous.

In this paper, we study the problem of trajectory tracking control for autonomous marines vehicles using robust sliding-mode controller. The proposed algorithm achieves good tracking performance of marine vehicle in the open sea in which there exist severe environmental disturbances and unknowns dynamic parameters. First, the dynamic model in task space of the marine vehicle system in horizontal motion is designed. By using position and velocity tracking errors, a robust controller is then developed based on a linear sliding-mode surface. The designed algorithm is chattering free due to hyperbolic tangent function in switching part. Based on the Lyapunov theorem, the stability in closed-loop system is guaranteed and the convergence of the position and velocity tracking errors are obtained. In addition, the robustness of the controller is verified when disturbances and uncertainties are introduced in the system. Extensive simulations are conducted to demonstrate the validity of the proposed algorithm.
The main goal of the project is to assure a collusion-free passage through the intersection in the shortest possible traveling time. Firstly, the order of the incoming vehicle is proposed. Using the mentioned order, a...
