| Abstract | Mobile ad hoc networks (MANETs) introduce new challenges to designing algorithms for solving the distributed mutual exclusion (MUTEX) problem. In this paper we propose the first permission-based MUTEX algorithm for MANETs. In order to reduce the messages cost, the algorithm uses the so called "look-ahead" technique, which enforces MUTEX only among the hosts currently competing for the critical section (CS). We propose mechanisms to handle the "doze" mode and "disconnection" of mobile hosts. The constraint of FIFO channel, which is not feasible in MANETs, is also relaxed. Using timeout, a fault tolerance mechanism is introduced to tolerate transient link and host failures. The simulation results show that the proposed algorithm works well under various mobility levels, load levels and system scales, especially when the mobility is high or load level is low. It is also shown that the algorithm has good scalability, especially when most of the requests come from a few active hosts. |

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.
