| Abstract | Because of the explosive development of different wireless technologies, mobile users can now access multiple wireless networks simultaneously. In this environment, a multiple path scheduling algorithm can improve the performance of the wireless networks and ensure high quality of video streaming for mobile users. This may not be the case, however, for TCP flows. One key reason is the occurrence of out-of-order packets resulting from different delays in alternative paths. Another is packet loss stemming from the unstable channel status of wireless networks. To better exploit multiple path scheduling for TCP flows, this paper proposes a new scheduling algorithm called Adaptive Packet Transmission Scheme (APTS) for multi-homed devices. Our scheme accurately estimates the available bandwidth of wireless networks using a TCP-Friendly Rate Control for Wireless Networks (TFRC-WN) scheme. APTS also distributes TCP packets to the multiple paths simultaneously according to the estimated available bandwidth. Our scheme effectively reduces the number of out-of-order packets by predicting the receiving sequences. Through simulation results, we prove that our scheme improves the performance of TCP and the video quality of mobile users. |

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.
