| Abstract | Power-line communication (PLC) is widely used as it offers high data-rates and forms a network over electrical wiring, an existing and ubiquitous infrastructure. PLC is increasingly being deployed in hybrid networks that combine multiple technologies, the most popular among which is WiFi. However, so far, it is not clear to which extent PLC can boost network performance or how hybrid implementations can exploit to the fullest this technology. We compare the spatial and temporal variations of WiFi and PLC. Despite the potential of PLC and its vast deployment in commercial products, little is known about its performance. To route or load balance traffic in hybrid networks, a solid understanding of PLC and its link metrics is required. We conduct experiments in a testbed of more than 140 links. We introduce link metrics that are crucial for studying PLC and that are required for quality-aware algorithms by recent standardizations of hybrid networks. We explore the spatial and temporal variation of PLC channels, showing that they are highly asymmetric and that link quality and link-metric temporal variability are strongly correlated. Based on our variation study, we propose and validate a capacity estimation technique via a metric that only uses the frame header. We also focus on retransmissions due to channel errors or to contention, a metric related to delay, and examine the sensitivity of metrics to background traffic. Our performance evaluation provides insight into the implementation of hybrid networks; we ease the intricacies of understanding the performance characteristics of the PHY and MAC layers. |

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.
