| Abstract | Mobile ad hoc networks (MANETs) raise new challenges in designing protocols for solving the consensus problem. Among the others, how to design message efficient protocols so as to save resource consumption, has been the focus of research. In this paper, we present the design of such an efficient consensus protocol. We consider the system model for MANETs with host crashes, but equipped with Chandra-Toueg's unreliable failure detectors of class /spl diams/P. At most f hosts can crash where f < n/2 (n is the total number of the hosts). The protocol adopts the coordinator rotation paradigm to achieve consensus. Unlike existing consensus protocols, the proposed protocol is based on a two-layer hierarchy with hosts associated with proxies. At least f + 1 hosts act as proxies and each host is associated with one proxy host. The messages from and/or to the local hosts of the same proxy are merged so as to reduce the message cost. Moreover, the hierarchical approach can improve the scalability of the consensus protocol. Performance analysis shows that the proposed protocol can significantly save cost compared existing protocols. |

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.
