| Abstract | Next generation mobile and wireless communication systems beyond 2020, aka Fifth Generation (5G) systems, aim at providing ubiquitous user experience with the utmost in quality. One of the promising technologies targeted for 5G systems is the flexible network deployment based on nomadic nodes (NNs). An NN is a low-power movable access node that provides coverage extension and capacity improvement on demand. Yet, NNs require flexible backhaul. One possible cost-efficient realization for flexible backhaul is in-band relaying. In this context, the capacity of the wireless backhaul link between an NN and its serving base station (BS) has a crucial role in the achievable end-to-end performance. The flexible backhaul can be exploited by dynamic NN selection to overcome the limitations of the backhaul link and, thus, to enhance the system performance. To this end, dynamic NN selection is carried out via selecting the serving NN from a set of available candidates considering the signal-to-interference-plus-noise ratio (SINR) on the backhaul link. In this regard, coarse NN selection takes into account only shadowing. Nevertheless, as NNs are stationary or slowly moving during operation, the wireless channels pertaining to NNs are usually subject to simultaneous impairments by both shadowing and multi-path fading, i.e., composite fading/shadowing. In this paper, we present the performance of coarse NN selection in composite fading/shadowing environments with co-channel interference. Further, we evaluate the performance in terms of backhaul link SINR, link rates, and end-to-end rate. Results show that coarse NN selection can yield high performance improvements. |

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.
