Abstract | A radio network (RN) is a distributed system where each node is a small hand-held commodity device called a station, running on batteries. Each station spends energy while transmitting or receiving a message i.e., when the station is awake. A station conserves power by going into a sleep mode. Since it is not possible to recharge batteries when the stations are on a mission, it is extremely important that the stations spend energy only when it is necessary. In this paper, we design an energy-efficient protocol for permutation routing on a single-hop radio network, where each station is within the transmission range of all other stations. An instance of the permutation routing problem involves p stations of an RN, each storing n/p packets. Each packet has a unique destination address which is the identity of the destination station to which the packet should be sent. Our goal is to route all the packets to their destinations while spending as little energy as possible. From simulation results, it is clear that our protocol performs better than an existing protocol by Nakano et al. [12], when each station routes packets with random destination addresses. We also assume that k « p « n, where, n, p and k are respectively the number of packets, number of stations and number of channels in the network. |

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.
