| Abstract | Wireless sensor nodes typically switch between sleep and wake periods. This poses a rendezvous problem on message senders and recipients. X-MAC, a state of the art sensor network medium access control (MAC) protocol, solves this problem by sending a strobe of short preambles from the message sender until the message recipient wakes up. Upon wake-up, the recipient receives the next strobe, signals the message sender that it is ready to receive, and the message transmission can take place. In sink oriented communication, geographic greedy routing, and link reversal routing, a forwarding node may have more than one potential next hop forwarding node. X-MAC does not support such opportunistic communication patterns. Instead it requires the sender to name the recipient explicitly. However, preamble length can be saved when message transmission starts as soon as the first one of the set of potential next hop nodes is waken up by a preamble. This requires PaderMAC, a new MAC protocol, where the decision on the next hop node is shifted from the sender to the receiver. This work specifies the PaderMAC protocol, explains the implementation of that protocol using TinyOS and the MAC layer architecture (MLA), describes a contribution to the MLA which is useful also for other MAC layer implementations, and presents the results of a testbed and theoretical performance study. The testbed study compares PaderMAC in conjunction with opportunistic routing to X-MAC in conjunction with path-based routing and shows how PaderMAC reduces the preamble length, better balances the load and further improves the end-to-end latency within the network. |

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.
