| Abstract | Energy balancing is an essential issue for scenarios of multi-hop wireless networks powered by batteries, for example, in disaster relief applications. In this paper, we propose a new transmission scheduling policy to extend the lifetime of a linear chain topology based multi-hop wireless multimedia network by maximizing the energy-balancing between routers. Two error-control techniques, Forward Error Correction and Automatic Repeat reQuest (ARQ), are adaptively deployed by the proposed strategy to achieve the maximal energy-balancing with the minimal quality requirement constraint. By considering the energy-balancing and the lower bound of multimedia quality constraint, the optimal channel coding redundancy and the optimal ARQ data retransmission strategy are applied to multimedia packets when those packets pass through each router in data transmission. To reduce the computing complexity, we simplify the solution by grouping multimedia packets with similar quality contribution, separating the global quality requirement into multiple local quality requirements, and allocating the optimal local quality requirement to each multimedia packet group. The simulation results show the proposed approach can significantly improve energy-balancing and lifetime of the multi-hop wireless multimedia network in both linear chain topology and more complex topologies. |

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.
