Wireless communication

1. INTRODUCTION: Ad hoc networks are a new prototype of wireless communication for mobile hosts (which we call nodes).In an Ad hoc network, there is no fixed particular infrastructure such as base stations and mobile nodes. Mobile nodes that are within each other’s radio frequency range communicate directly via wireless links, while those that are far apart depend on other nodes to forward messages as routers. Ad hoc networks are peer to peer networks of mobile nodes. They are mostly used in sensor

WIRELESS NETWORK METHOD USING IN SMART GRID COMMUNICATIONS Ehsan Dolatshahi Independent Study April 22, 2015 Introduction 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

The paper presents the design of channel estimation and blocking probability for multi-hop wireless communication network (MH-WCN). This work proposed a bidirectional network coding 4−hop transmission strategy and followed by 2N−hop WCNs. The proposed method follows two steps. Firstly, assign composite channel coefficients at desired nodes and then derived the MSE performance expression for the proposed LMMSE estimation scheme, and an optimal training scheme has been designed to minimize MSE. Secondly

This article is a survey of all aspects of communications high- altitude platforms (HAPs), this balloons and aircraft stationed in the stratosphere between 17 and 22 kilometers. The technique can be considered as a new solution for the provision of telecommunications services. This poll contains some information and benefits . The following table shows the basics of the types of high- altitude platforms and comparison of HAPs, terrestrial networks , satellites , followed by information frequency

Bell Atlantic Mobile changed its name in 198 to Verizon Wireless, creating one of the largest mergers in business history. Verizon Wireless has had some struggle with globalization but it has become a major player when it comes to technology. Evaluate the vision and mission statements of Verizon Wireless and the impacts of stakeholders are just a few things that will be discussed in this report. On July 27, 1998, New York City based Bell Atlantic and GTE merged to become one of the largest telecommunications

computing and communication technologies. And a new technology evolves which is known as Wireless Sensor Networks (WSNs). Wireless Sensor Networks are a new kind of distributed systems that are an integral part of the physical space they inhabit. The massive growth in this technology has gathered the heed and imagination of many researchers, providing a broad spectrum of ideas to be implemented in various applications [2]. The grouping of various sensor nodes makeup a huge Wireless Sensor Network

growing in the wireless industry in Canada. The wireless industry in Canada presents a unique opportunity for investment due to the oligopolistic structure and market breakdown. Currently, there are three major players in the industry and there is extensive room for growth and development as an industry and for Wind Mobile itself to gain significant market share. Some of the factors I will consider over the course of this analysis and recommendation include: the wireless communication industry in Canada

are discussed. Underwater wireless communication networks are particularly vulnerable to malicious attacks due to the high bit error rates, large and variable propagation delays, and low bandwidth of acoustic channels. A complete survey of securing underwater wireless communication networks is presented, and the research challenges for secure communication in this environment are outlined.Acoustic channels have low bandwidth. The link quality in underwater communication is severely affected by multipath
