| Abstract | In the upcoming many-core era, chip multiprocessor architectures will be composed of hundreds or even thousands of processor cores, which interact among them through an on-chip communication platform for synchronization and data coherency/consistency purposes. As the traffic generated within the chip becomes more multicast-intensive, it is necessary to conceive novel communication platforms that go beyond conventional schemes and guarantee multicast support with high throughput, low latency, and low power. Nanotechnology provides an opportunity within this context by virtue of terahertz graphene antennas, which could allow the integration of one antenna per core in a Graphene-enabled Wireless Network-on-Chip (GWNoC). However, it is essential to design an appropriate MAC protocol in order to fully benefit from this novel approach. To provide a first contribution in this direction, in this paper we design two baseline MAC protocols based on the well-known ALOHA and carrier sensing techniques. Their functionalities have been properly conceived by taking into account characteristics and requirements of future chip multiprocessors systems. Moreover, their performances have been evaluated by means of computer simulations under different chip configurations. Obtained results demonstrate the pros and cons of these simple contention-based MAC protocols and pave the way for the future exploration of the MAC design space. |

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.
