There is a growing interest in providing Internet services to the mobile nodes. When mobile nodes travel from one router's service area to another, the time-sensitive applications may see degradation in service. We investigate into the effects of handoff on service quality of mobile nodes. Several experiments are conducted using various packet-metering schemes with or without transferring profi...

When implementing ramp metering in the context of freeway networks, traffic can spontaneously re-route due to the applied control actions. Although this re-routing can have an important impact on the resulting traffic situation in the traffic network and on the performance of the traffic network as a whole, re-routing is not automatically included in current model predictive frameworks for free...

Smart metering wireless sensor networks need to refer to a common time scale for several reasons. As examples: (i) in power quality, some measures at different nodes of the network are senseless if not synchronized; (ii) in security, in case of lack of synch, a replay attack could result successful; (iii) in billing, different times of the day can be charged differently. Generally, the synchron...

When creating a High-Dynamic-Range (HDR) image from a sequence of differently exposed Low-Dynamic-Range (LDR) images, the set of LDR images is usually generated by sampling the space of exposure times with a geometric progression and without explicitly accounting for the distribution of irradiance values of the scene. We argue that this choice can produce sub-optimal results both in terms of th...

This paper presents the state of the PV market in Greece, the achievements so far, the current situation and proposals for next years. The PV market environment in terms of new PV development policies is presented, such as netmetering. The net-metering long awaited program framework is expected to regenerate the PV market in Greece, It was finally introduced at the end of 2014 and the program p...

ITU-T G.9904 standard, also known as PoweRline Intelligent Metering Evolution (PRIME), is a Power Line Communications standard for advanced metering, grid control and asset monitoring defined by the International Telecommunication Union (ITU). In this paper, an analysis about how different characteristics of the communication channel and types of noise might affect the system performance is car...

In a classic example of a smart electrical metering application, the same type of wireless networks can be used to build an Advanced Metering Infrastructure (AMI) to continuously monitor the power consumption, control the functionality of the meters, as well as limit the end-user consumption or report about tampering with the meters in real-time. Such capabilities are important for enabling the...

The deployment of smart metering provides an immense amount of data for power grid operators and energy providers. By using this data, a more efficient and flexible power grid can be realized. However, this data also raises privacy concerns since it contains very sensitive information about customers. In this paper, we present a security and privacy-preserving metering scheme for the community ...

Today electronic communication technology became more advanced to give solutions in real time.. In this paper use the smart and efficient energy metering system uses GSM network.GSM is most popularly used because of its vast coverage area and its cost effectiveness. It is wireless two way communication between utility company and energy metering system..GSM based smart efficient energy meter se...

Research recently conducted at the University of Central Florida involving crashes on Interstate-4 (I-4) freeway in Orlando, Florida led to the creation of new statistical and neural networks models that are capable of determining rear-end and lane-change crash risks along the freeway in real-time. For determining the rear-end crash risk, it was found that rear-end crashes occur within one of t...
