| Abstract | The LWT-MAC protocol extends the normal operation of B-MAC by taking advantage of the local synchronization that can be achieved after each packet transmission. Sensor nodes wake up at the end of each successful transmission to send or receive messages eliminating the need for the long preamble transmission. Current LPL analytical models are extremely simple as they do not consider the energy waste due to collisions. In this work, a detailed analytical model of the LWT-MAC protocol, which considers the energy waste of collisions and overhearing for both saturated and unsaturated conditions, is presented. Results show a reduction of the energy consumption as the traffic increases and an improvement, in terms of throughput and delay, compared to B-MAC. Additionally, a performance evaluation is presented in which some key network parameters (check interval, traffic load and the number of sensor nodes) are modified in order to analyze the behavior of the studied LWT-MAC protocol. |

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.
