| Abstract | To further improve the cooperation efficiency and multiple access performance, we propose a novel multiple-recipient-based cooperative MAC protocol for wireless ad hoc networks. The sender selects a recipient among multiple candidate recipients. Candidate helpers employ a preliminary helper contention scheme and an optimal helper contention scheme to select the optimal helper according to their cooperation gain. Besides, the sender can send data packet at the highest data rate that it can support according to the busy tones in the preliminary helper contention process, guaranteeing both the channel utilization and the link reliability. Once the recipient receives the sender's data packet through the optimal helper, it can also send its data packet to the sender through the same optimal helper. Furthermore, the optimal helper can piggyback its data packet to the sender or the recipient, reducing the reservation overhead and the possibility of collisions during channel reservation. Simulation results show that, in the ad hoc network environment, the proposed protocol has better performance than CoopMACA and 2rcMAC in terms of throughput and average packet 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.
