| Abstract | We propose a reliable multicast MAC protocol for channel efficiency and LPD (low probability of detection), a capability that enhances survivability, assisted by multicarrier direct-sequence code-division multiple access (MC-DS/CDMA) scheme in tactical ad-hoc networks. For a reliable multicast based on IEEE 802.11 standards constructing RTS-CTS handshake, a multicast sender has to receive consecutive CTSs and ACKs from all multicast receivers. These cumulative CTSs and ACKs degrade network efficiency. Furthermore, the cumulative signals of CTSs and ACKs can be easily detected by an enemy detector. In the proposed protocol, CTS/ACK messages can be transmitted concurrently through the MC-DS/CDMA mechanism. This can reduce the transmission overhead generated by consecutive CTSs and ACKs. Also, the cumulative signal strength of CTSs/ACKs can be reduced, since the mechanism can spread CTS/ACK transmission power by spreading gain of the MC-DS/CDMA code. The proposed protocol is thoroughly examined by theoretical methods and simulation. Results show that it significantly improves the performance and the survivability of tactical ad-hoc networks. |

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.
