Abstract Our paper explores the issue of how to provide appropriate qualityof Service mechanisms closely integrated with flexible mobilitymanagement in wireless local area networks. We consider them asaccess networks of choice for the high performance Wireless MobileInternet. We present a hierarchical QoS architecture that extendsDifferentiated Services (DiffServ) to mobile hosts in awireless environment. Our approach is based on controlling severalparameters of a wiireless LAN cell: the limited geographicaL spanto ensure the same high bit rate for all hosts, the constrainedrate of traffic sources to limit the use of the channel in functionof the required QoS and the limited number of active hosts to keepthe load sufficiently low. The QoS management is coupled withmobility management at the IP level. We use a micro-mobility schemeimplemented in the IPv6 layer with fast hand-offs between adjacentcells. Micro-mobility avoids address translation, traffictunnelling, and enables fast hand-offs. We give some details ofexperiments to show the quality of service diffferentiation overthe 802.11b network.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
