| Abstract | Frequent use of various mobile application services consumes a great amount of battery power in mobile devices. In order to satisfy user convenience and keep the portability of mobile devices, a power saving mechanism is essential for the success of mobile communication technologies. This paper evaluates performances of the power saving mechanism of IEEE 802.16m, one of the solutions for the fourth generation mobile communication technology. When a mobile device does not communicate with a base station, it temporarily shuts down communication-related modules and circuits in order to save the battery power. During that period, the device cannot listen to incoming traffic from the base station, which causes an inevitable delay at the expense of reducing power consumption. Arriving packets are transmitted only after the device enters either the awake mode or the listening window in the sleep mode. Four power saving mechanisms are examined in the simulation:1) fixed maximum operating parameters, 2) fixed minimum operating parameters, 3) moving average policy, and 4) exponential increase policy. To evaluate the performance of the sleep mode operation in IEEE 802.16m, an analytical model is developed for delay time based on M/D/1 queueing system. Performances of the power saving mechanisms are evaluated with Poisson and traffic models for five applications: WEB, FTP, GAME, VIDEO, and VOICE, which reflects real service environment. |

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.
