| Abstract | A new and reliable MAC protocol is proposed to reduce the number of control handshake messages, such as RTS (Request-To-Send) and CTS (Clear-To-Send), incurred prior to data transmission in ad hoc wireless networks. Such a handshake is currently being used in the IEEE 802.11 DFWMAC (Distributed Foundation Wireless MAC) protocol. Our protocol is power efficient since fewer control messages are being used. By overhearing the ACK message sent by the upstream node, a node can gain advance knowledge that data would be arriving and hence need only to initiate a CTS later on. In addition to this, we introduce reliability into the protocol using an acknowledgment message to indicate that the data transmitted has been reliably received. Issues related to collision of control messages are also addressed in this paper. The communication performance of our protocol is evaluated via simulation and we also compare it with the IEEE 802.11 DFWMAC. Results show that our protocol outperforms DFWMAC with fewer control overheads incurred and smaller end-to-end delay. |

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.
