Modeling And Delay Analysis Of Wireless Home

Historically, this challenge has been tackled through technological innovation, through for example the development of more energy efficient electrical equipment (Yun, et al., 2011).

This report covers the real-time system design and the different components of the SCADA Energy Management System. Specifically, this report will focus on the General Electric XA/21 SCADA system and how it all fits together and how it provides a solution to end-users and administrators. The XA/21 is a very scalable and customizable system and that will be described at great length in this report (General Electric, 2013).

There are a lot of problems for our world today when it comes to energy.

The Smart Grid is an improvement of the infrastructure in the energy sector to have a secure and reliable system that improves growth and security. The grid system works with two integrated systems, one is for electricity while the other is for the information. It is a combination of several technologies that help mitigate problems of electricity. Many people do not understand what Smart grid is and tend to be skeptical on the subject. The people in the energy sector are looking at each other to figure out who will employ the technology first. The Smart grid technology should be employed both at the public and the private

Wireless networking signals are also susceptible to interference from lights and electronic devices as wireless networks use radio signals for transmission. Then there is the issue of stability, because of the interference caused by different electronic devices, often the wireless connection gets lost or distorted. Although the transmission range of a common 802.11g network is on the order of tens of meters and is quite sufficient for a typical home but it is not sufficient for a large setup. In order to increase the range, additional equipment/access points and repeaters will have to be developed and thus the cost will further go up. The transmission speed of wireless networks is slow as compared to the slowest common wired networks. Faster options like gigabit Ethernet are available via cables and are being deployed in specialized environments where the throughput of a wired network is

In recent years, there has been a rise in the demand of power (electricity). This is due to the development of cities, urban, sub-urban and rural areas and robust economic growth. The increased demand has exhausted the surplus power generation available, thus demand cannot be meet (Eskom).

A key solution to the energy storage and wastage problems is offered by renewable energy sources; however, their integration with the existing grids comes with a set of barriers such as the intermittency of generation and the high level of distribution of the sources and the lack of proven distribution control algorithms to manage such a highly distributed generation base [2]. In such situation, the use of communication and information technologies is attractive to match the demand to the available supply and dramatically improve performance and efficiency. A smart grid is an intelligent electricity network that integrates the actions of all users connected to it and makes use of advanced information, control, and communications technologies to save energy, reduce cost and

Smart grid has four major area of applications which are industries and homes, transmission and distribution, generation, and power system as a whole.

Having a wireless hearing device does put you in an advantageous position as the user does not have to sit in one position and use it. Instead, he can move about and use the headset in a comfortable manner. However, if you end up with a wireless headset that does not have a good battery life; you would be spending half of your day in recharging it. The users of Plantronics Voyager Edge definitely do not fall in this category and they do not have to go through the trouble of recharging their device after short time intervals.

Generally, smart grids technologies can be put into four functional categories: Information collectors; information assemblers, displayers, and assessors; information-based controllers and energy resources. Smart grids collected data from various types of sensors. These sensors measure performance-related characteristics of electricity system components. Assessors are used to analysis and display the information they received from the devices. The information-based controllers devices will use the information that they received to control the other devices behavior to achieve the goal. Energy or power resources include the technologies that can used to generate, store, or reduce demand for electricity.

Abstract — The Delay Tolerant Networking (DTN) aims at providing effective medium for communicating where no continuous connectivity is guaranteed for a given network. It is really important especially when there are faulty nodes in a network. Mobile Sensor Networks are one of the most fault prone networks due to its inherent nature of limited resources. Existing routing schemes promotes the algorithms to make use of message replication to ensure high delivery rate for messages. Protocols that rely on message replication or flooding mechanisms contribute to overhead in network communication by producing large number of duplicate packets. This paper gives research findings along with a survey on performance of DTN routing protocols which

Abstract—To meet the Electric Power demands of a fast expanding economy, smart grid (SG) are expected to have reliable, efficient, secured and cost-effective power management system. Additionally, energy demands from the users change dynamically in different time-periods (such as on-peak , and off-peak) , which required dynamically availability

The old generation of electrical power grid has taken care of our needs in the past. However, as our world progress technologically, so do the expectations from different infrastructures around us. Smart grid is an initiative to completely restructure the electrical power grid to meet the current and future requirements of its clients. Upgrading our electrical power grid could bring novel security vulnerabilities into the system. Thus, security is one of the key parts in smart grid technology. Smart grid technology also puts more reliability demands on WAN (wide area network) infrastructures. [1]

This report is meant to give an overview about the smart grid and smart meters by describing what is the smart grid and smart meter. In addition, it introduces several technologies from these power grid systems and how these technologies impact on the environment and renewable resources. The report also presents the benefits of using the smart grid and smart meters, which associated with our way of life. Thus, the disadvantages will also be discussed.

This memorandum addresses to present an overview of the features, functionalities, and characteristics of the Smart Grid. It expounds the effects of Smart Grid technologies on the modern electricity grid, power industry, and society. Smart Grids came up as a solution to make the electricity grid more adapt to the demand of the times, make it more sustainable, greener, and more efficient to the delivery of electric power. Smart Grids are more self-governing and enhance the higher effectivity and efficiency of power delivery, and they also allow renewable energy recourses safely to connect into the grid to replenish the power supply from the normal customers’ distributed power plants and storage, power industries can minimize the cost to build more power plants with renewable energy, transmission lines, and substations to raise the level of power supply which to adapt to the modern electricity consumption. This memorandum can help people learn more about Smart Grids, the better understanding of its value, the less resistance to the construction of it, the faster promotion of the development of it. The purpose of it is to introduce what the Smart Grid is, present the discussion of its features and related technologies, demonstrate how these technologies will influence the modern electricity grid as well as keep on developing and
