| Abstract | Energy harvesting (EH) is an effective method to reduce power consumption of wireless networks. In this paper, we investigate the use of EH relays that harvest energy via RF radiation from the source node into finite energy buffers to forward the source data. For a multi-relay network, a proactive selection protocol is considered which employs a single best relay to forward source data and let the remaining relays to harvest energy simultaneously. We develop a discrete-time Markov chain to capture the variation of the energy buffer status, and derive the outage probability and the diversity order of the considered protocol. Numerical results are reported to validate the analysis accuracy along with extensive discussions on the impact of numerous system parameters, including the energy buffer size and the quantization resolution, energy conversion efficiency, number of relays, for both balanced and unbalanced channel settings. |

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.
