| Abstract | The Internet of Things (IoT) is an application-driven heterogeneous network, being rapidly deployed across the world. The proposed session layer for IoT is the upcoming standard for Constrained Application Protocol (CoAP). The transport layer of choice for IoT is emerging to be UDP. CoAP itself mandates usage of UDP only as the transport layer. It is well-known that practical usage of UDP requires extra employment of congestion control, generally in form of rate control. For bursty source data that is generated most of the while in IoT, usage of rate control is a must. Configuring the rate control parameters requires knowledge of the performance of the underlying network. In this paper, we first experimentally measure, analyze and model performance parameters, e.g. avg. bandwidth, round-trip delay and jitter, of a real heterogeneous wide area network. Based on the analysis, we then provide two novel, intuitive algorithms for source node rate control, and destination node timer management. These algorithms were found to improve the reception performance over that achievable using guidelines provided in RFC 5405. For delivery of urgent/critical data in IoT, we had earlier proposed usage of session-level forward error control (FEC) of the communicated data. Usage of our algorithms ensured that the deployment of the FEC scheme, which employed lightweight rate-10/11 Reed-Solomon codes, succeeded 98% of the while, while sending as many as 10 packets per burst. The algorithms can be re-used with similar high performance levels, in many other communication contexts also, that entail low-volume, bursty data traffic visualized in RFC 5405. Hence the algorithms may be considered for augmentation of CoAP standard. |

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.
