An Analisys of Business VPN Case Studies
A VPN (Virtual Private Network) simulates a secure private network through a shared public insecure infrastructure like the Internet. The VPN protocol provides a secure and reliable access from home/office on any networking technology transporting IP packets. In this article we study the standards for VPN implementation and analyze two case studies regarding a VPN between two routers and two firewalls.VPN; Network; Protocol.
A Zigbee Technology for Lighting Control Application
Zigbee is wireless communication technology and IEEE 802.15.4 standards for data communication. There are zigbee standards provides network security and application sup port services operating on top of the IEEE 802.15.4 medium access control and physical layer wireless standards and it employs a group of technologies to enable scalable, self - organizations,self - healing networks that can mange various data traffic pattern s. The Zigbee is low - cost, low - power consumption, wireless mesh networking standards and It is designed around low power consumption allowing batteries to essentially last forever. Zigbee is use for monitoring and control applications. This paper presents a zigbee device types, its traffic varities, stucture and use in home automation and the lighting control application
Peace Driving: Case Studies of Wi-Fi Usage
Wireless networking technologies, under the umbrella of the IEEE 802.11 suite of standards and commonly referred to as Wi-Fi, is now commonplace technology in both the home and office. In this work, we present the results of studies into wireless networking uptake and security within two town communities in the UK. Our work concentrates on the geographical positioning of wireless access points (APs) and the security measures used to protect these liberating technologies from unwanted misuse, often referred to as war driving, we employ the title peace driving, for wireless networking surveying which aims to address security issues in wi-fi networks. The results from our study show significant uptake of wireless networking in both the residential and business areas surveyed. The number of access points present in some residential areas is large, and given the relatively small distances between access points there is undoubtedly traffic which is crossing private boundaries. These findings are corroborated across both the communities which were studied. We suggest that similar sized and constituent communities are representative of others in the UK and find similar trends between the two studied as part of this work
Smart Grid Communications: Overview of Research Challenges, Solutions, and Standardization Activities
Optimization of energy consumption in future intelligent energy networks (or
Smart Grids) will be based on grid-integrated near-real-time communications
between various grid elements in generation, transmission, distribution and
loads. This paper discusses some of the challenges and opportunities of
communications research in the areas of smart grid and smart metering. In
particular, we focus on some of the key communications challenges for realizing
interoperable and future-proof smart grid/metering networks, smart grid
security and privacy, and how some of the existing networking technologies can
be applied to energy management. Finally, we also discuss the coordinated
standardization efforts in Europe to harmonize communications standards and
protocols.Comment: To be published in IEEE Communications Surveys and Tutorial

A business planning framework for WiMAX applications
Mobile networking refers to wireless technologies which provide communications between devices. Applications for mobile networking have a broad scope as they can be applied to many situations in either industrial or commercial sectors. The challenge for firms is to better match market-induced variability to the organizational issues and systems necessary for technological innovation. This chapter develops a business planning framework for mobile networking applications. This framework recognises the fluidity of the situation when trying to anticipate and model emerging wireless applications. The business planning framework outlined in this chapter is a generic model which can be used by companies to assess the business case for applications utilizing mobile networking technologies
