WiMax

Abstract:The IEEE 802.16 family of standards, and its associated industry consortium WiMax, promises to deliver high data rates over large areas to a large number of users in the near future. This exciting addition to current broadband options such as DSL, cable, and Wi-Fi promises to rapidly provide broadband access even to locations in the world’s rural areas.

WiMAX

Abstract:

The two driving forces of modern Internet are broadband, and wireless. The WiMax standard combines the two, delivering Internet access over a wireless connection. The main problems with broadband access are that it is pretty expensive and it doesn’t reach all areas. The main problem of WiFi access is that hot spots are very small, so coverage is sparseDownload Full Paper: Click here

Digital Jewellary Made Possible Using Wireless Communication

Abstract: Mobile computing is beginning to break the chains that tie us to our desks, but many of today's mobile devices can still be a bit awkward to carry around. In the next age of computing, there will be an explosion of computer parts across our bodies, rather than across our desktops. Basically, jewelry adorns the body, and has very little practical purpose. However, researchers are looking to change the way we think about the beads and bobbles we wear. The combination of microcomputer devices and increasing computer power has allowed several companies to begin producing fashion jewelry with embedded intelligence i.e., Digital jewelry. Digital jewelry can best be defined as wireless, wearable computers that allow you to communicate by ways of e-mail, voicemail, and voice communication. This paper enlightens on how various computerized jewelry (like ear-rings, necklace, ring, bracelet, etc.,) will work with mobile embedded intelligence.
It seems that everything we access today is under lock and key. Even the devices we use are protected by passwords. It can be frustrating trying to keep with all of the passwords and keys needed to access any door or computer program. This paper discusses about a new Java-based, computerized ring that will automatically unlock doors and log on to computers.

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.
