| Abstract | Power-aware routing in wireless ad hoc networks has been extensively explored in recent years, and various routing metrics were developed for the prolongation of network lifetime. This work studies power-aware routing so as to maximize the minimum remaining energy of all nodes after routing. This routing metric, referred to as Maximum-Residual Routing, aims at maintaining the minimum remaining energy as high as possible so as to delay the fist failure time of nodes in the network. In this paper, a polynomial-time optimal algorithm is proposed for Maximum-Residual Multicasting. We then show that Maximum-Residual Aggregating is $${\mathcal{NP}}$$ -hard and that, unless $${\mathcal{P = NP}},$$ its minimization version cannot be approximated within a ratio better than (2 − ε) for any ε > 0. The proposed routing algorithm for Maximum-Residual Multicasting can be applied to existing routing protocols, especially those based on the link-state approach. The capability of the algorithm was evaluated by a series of experiments, for which we have very encouraging results in network lifetime and load balance. |

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.
