In present days, home devices with network capabilities are widely used and augmented for delivering several Home Services (HS) to more end users. The technology integration offers new and exciting opportunities to increase the device connectivity within a home for many proposals of home automation. This paper is designed and implemented for a cost effective, flexible, manageable home automation system. The proposed system consists of three main components: a device control using a micro controller (e.g., Raspberry PI with control circuit), a notification system (Social network integration) and a user control from anywhere, any time and any device. This system can support a wide range of home appliances connecting through the network as the Internet of Things (IoT) concept. A user is able to easily control home automation system by several ubiquitous devices. Air conditioners and fans are sample devices to be controlled by our system in order to demonstrate the simplicity and effectiveness that will save usage energy. Read More Read Less

Abstract It was summed up purpose of this work is to compare the models of spread for the small urban cells in GSM, with objective to test their behaviour.

It was summed up purpose of this work is to compare the models of spread for the small urban cells in GSM, with objective to test their behaviour. Engineering radio constitutes one of the most important aspects during the deployment of a cell network as much as it is responsible for the quality level of service given to the subscribers. In environment to indoor, the sign is subjected to different weakening that can attain 30 dB. In effect, the spread in this middle depends on several characteristics to know the architectural data of buildings, in other words types of used building materials, the size of the windows, etc. We are interested in this paper to introduce different models of prediction of urban spread in environment. After different comparisons, we concluded that the model of COST-CNET is the most appropriate to make a prediction of weakening for a local zone with strong concentration. Read More Read Less

Abstract This paper investigates an Adaptive Power Control based Energy Efficient Routing scheme, referred to as PCGRACE, which takes advantage of both efficient energy utilization and transmission power control strategy. Thus, transmission power control strategy is incorporated with energy efficient routing. Experimental results are obtained by using the Sun SPOT-based wireless sensor test bed. The experimental results show that the routing... This paper investigates an Adaptive Power Control based Energy Efficient Routing scheme, referred to as PCGRACE, which takes advantage of both efficient energy utilization and transmission power control strategy. Thus, transmission power control strategy is incorporated with energy efficient routing. Experimental results are obtained by using the Sun SPOT-based wireless sensor test bed. The experimental results show that the routing technique results in an increase in the energy efficiency of the network and thus, an improvement in the network lifetime. Read More Read Less
