| Abstract | Stream Control Transport Protocol (SCTP)-based handover is supposedly the best suit for current mobile Internet users. However, prevalent SCTP-based handover solutions mostly evaluate candidate networks by a function of multiple attributes such as available bandwidth, delay, etc., which tend to vary often in burst and might cause the instability of handover decisions. Moreover, the SCTP congestion control strategy leads to sudden degradation of users’ quality of experience for multimedia streaming service because of abrupt and frequent strong fluctuations in the transmission rate. In this paper, we propose a novel QoS-driven SCTPbased handover solution (SCTP-QD) appropriate for heterogeneous wireless multimedia transmission. A new network service and transport layer QoS-aware model is designed to help SCTP-QD accurately analyze the service stability and data transmission capacity for each path. A proper QoS-driven handover decision model is introduced in SCTP-QD in order to improve the SCTP handover efficiency while reducing unnecessary handoffs and fail-over probability. A proposal is finally addressed to help SCTP-QD avoid the slow start phase whenever handover occurs. The simulation results show that SCTP-QD outperforms existing solutions in terms of data delivery performance. |

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.
