Free Space Optics

Abstract:

This paper deals with communication through optics using one of the latest technologies called the free space optics (FSO).FSO may sound new and experimental but in fact it predates optical fiber and has its roots in wartime efforts to develop secure communication systems that did not require cable and could withstand radio jamming.Download Full Paper: Click here

Satellite-Cellular Communication

Abstract:

The modern day technology trends have made the world a global village, making every thing compact. One such trend is the invention of the cellular communications. The cellular communication has made new milestones in the fieldof communication. This technology has revolutionized the wireless communicationfield. Now cellular markets are glooming because of the increase in the number of users. The cellular users are exponentially increasing in the past few years.Download Full Paper: Click here

Virtual Reality

Abstract: Virtual Reality (VR) is presently a hot, up to date topic in the field of computer science. Virtual reality can be defined as “a computer system, which is used to create an artificial world with an ability to navigate through that world and manipulate objects in that world.” The two types of VR are immersive VR and non immersive VR. The most commonly used concepts for developing 3D worlds are Rendering and Programming .we can also involve in the VR using some hardware components like head mounted display (HMD), Cave automatic virtual environment (CAVE). The virtual reality system create full color 3 dimensional images, track the user’s body movements and changes the image instantly as the user interacts and moves through the virtual world. Some of them are window on world (WOW), immersive systems and telepresence. The VR concept is used in many applications like in scientific, education, and training fields. In the nearby future virtual reality will become better cheaper, and more accessible. Virtual reality is a very powerful user interface technology and can become a blessing to the world if used to its potential.

End-To-End Qos Architecture (4G Wireless Communication)

Abstract: This paper describes an architecture for differentiation of Quality of Service in heterogeneous wireless-wired networks. This architecture applies an “all-IP” paradigm, with embedded mobility of users. The architecture allows for multiple types of access networks, and enables user roaming between different operator domains. The overall 4G architecture discussed in this paper is IPv6-based, supporting seamless mobility between different access technologies. Mobility is a substantial problem in such environment, because inter-technology handovers have to be supported. In our case, we targeted Ethernet (802.3) for wired access; Wi-Fi (802.11b) for wireless LAN access; and W-CDMA - the radio interface of UMTS - for cellular access.The architecture is able to provide quality of service per-user and per-service An integrated service and resource management approach is presented based on the cooperative association between Quality of Service Brokers and Authentication, Authorisation, Accounting and Charging systems. The different phases of QoS-operation are discussed. The overall QoS concepts are presented with some relevant enhancements that address specifically voice services. In particular, EF simulations results are discussed in this context.
