| Abstract | Nanotechnology is enabling the development of integrated devices just a few hundred nanometers in size. Communication among these nano-devices will boost the applications of nanotechnology in the biomedical, environmental and military fields. Within the communication alternatives at the nanoscale, the state of the art in nanomaterial research points to the Terahertz band (0.1–10 THz) as the frequency range of operation of graphene-based electromagnetic (EM) nano-transceivers. This frequency band supports very large transmission bit-rates and enables simple communication mechanisms suited to the limited capabilities of nano-devices. Due to an expectedly very large number of nano-devices sharing the same channel, it is necessary to develop new Medium Access Control (MAC) protocols which will be able to capture the peculiarities of nanonetworks in the Terahertz band. In this paper, PHLAME, a physical layer aware MAC protocol for electromagnetic nanonetworks, is introduced. This protocol is built on top of a novel communication scheme based on the exchange of femtosecond-long pulses spread in time, and exploits the benefits of novel low-weight channel coding schemes. In the PHLAME protocol, the transmitting and receiving nano-devices jointly select the communication parameters that minimize the interference in the nanonetwork and maximize the probability of successfully decoding the received information. The performance of the protocol is analyzed in terms of energy consumption, delay and achievable throughput, by taking also into account the energy limitations of nano-devices. The results show that, despite its simplicity, the PHLAME protocol is able to support densely populated nanonetworks by exploiting the peculiarities of the Terahertz band. |

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.
