|Abstract||Transmission Control Protocol (TCP) is the most commonlyused transport protocol on the Internet. All indications assurethat mobile computers and their wireless communication links willbe an integral part of the future internetworks. In this paper, wepresent how regular TCP is well tuned to react to packet loss inwired networks. We then define mobility and the problems associatedwith it. We discuss why regular TCP is not suitable for mobilehosts and their wireless links by providing simulation results thatdemonstrate the effect of the high bit error rates of the wirelesslink on TCP performance. We discuss and illustrate the problemscaused by the mobility of hosts using a graph tracing packetsbetween fixed and mobile hosts. We then present a survey of theresearch done to improve the performance of TCP over mobilewireless networks. We classify the proposed solutions into threecategories: link layer, end-to-end and split. We discuss theintuition behind each solution and present example protocols ofeach category. We discuss the protocols functionality, theirstrengths and weaknesses. We also provide a comparison of thedifferent approaches in the same category and on the categorylevel. We conclude this survey with a recommendation of thefeatures that need to be satisfied in a standard mobile TCPprotocol.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at Indian Institute of Technology Kharagpur.
NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
