| Abstract | The optimal consumption of energy is one of the most important aims in Wireless sensor networks. Among influential factors in reducing the energy consumption ratio, we can mention intelligent allocation of channel to node and sending the data with the least rate of interference with other nodes. The successful execution of this act by MAC sub-layer depends on determining optimal values for factors such as percentage of duty cycle, random time to retest the channel an etc. Duty cycle, defined as the ratio of listening period to total period of listening and sleeping, is of great importance as the parameter of regulating node sleeping and listening time for ideal consumption of energy. There is presented an algorithm based on learning automat, called LA-MAC, which tries to reduce energy consumption by regulating optimally the duty cycle value, thereby increasing the lifetime of network. In this algorithm, each node is equipped with a learning automat which determines the value of duty cycle in terms of residual energy and preconfigured lifetime. The results of simulation in the environment of NS simulator confirm the efficiency of LA-MAC from four factors of the death time of the first node, end-to-end delay, average network lifetime and the number of survived nodes at the end of simulation, performed in two different scenarios while compared with A-MAC and S-MAC with various duty cycles. |

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.
