| Abstract | It is well-known that due to the nature of some ad hoc network applications, Transmission Control Protocol (TCP) instability can have a devastating impact on the quality of service requirements. TCP instability is truly a cross layer problem which needs to be addressed by considering the interaction of multiple layers with each other. In this paper we first report our reconfirmation of some simulation results in the context of a string topology network that uses the IEEE802.11 medium access control protocol, and an ad hoc routing protocol. We then discuss why the performance of TCP is poor in this scenario. A simple solution is proposed that enables the DSR routing protocol to reduce its trigger of unnecessary route error process due to MAC collisions which interrupts and affects the TCP operation leading to deteriorated and unstable TCP throughput. Our proposed solution enforces the TCP sender to recover packet losses of data by fast retransmit / fast recovery TCP mechanism without resorting to the coarse grained Retransmission Timeout (RTO) , which is often detrimental to throughput. It is shown that this modification can eliminate TCP throughput instability which is regarded as one of the main TCP problems in multi-hop ad hoc networks. |

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.

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 Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
