| Abstract | In wireless sensor networks (WSNs ), one of the important challenges is to achieve a satisfactory network lifetime while meeting quality of service requirements. A number of energy efficient protocols have been proposed, mostly based on a layered design approach, which means that they are focused on designing optimal strategies for “single” layer only. In this paper, a novel cross layer-based MAC protocol abbreviated as CLMAC is proposed. In CLMAC, the interactions among MAC, Routing and Physical layers are fully exploited to reduce energy consumption and multi-hop delay of the data delivery for wireless sensor networks. More precisely, in CLMAC, the carrier-sensing technology in physical layer is applied to sense traffic and compulsorily wake up the neighbor nodes within multi-hops, so the data transmission over multi-hops can be realized during a single listen/sleep cycle, it can maximize a sleeping duration of each node under delay guarantee of the data delivery. Meanwhile through adopting routing layer information, CLMAC only make receiver of the next hop on the path of routing be adaptively waken up, Thus, it can reduce energy consumption of the nodes. Through the performance analysis and the simulation study using the NS-2, we evaluate the performance of CLMAC and prove its substantial advantages such as lower energy-consumption, lower latency and larger data throughput compared with ASMAC, especially in aspect of latency performance. |

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.
