| Abstract | Wireless sensor and actuator networks (WSANs) are expected to be come fundamental technologies supporting machine-to-machine (M2M) communication and the internet of things (IoT). However, wireless sensors face inherent limitations because they must provide high demand response (DR) despite severely limited battery power. In an effort to achieve both power-saving characteristics in addition to high DR, we are working on research and development of radio-on-demand sensor and actuator networks (ROD-SANs), in which each node is equipped with a wake-up receiver that allows all nodes to stay in sleep mode most of the time, and transmit only after a wake-up signal is received. Since the wake-up signal can also include channel information, the sender nodes can direct the receiver nodes to switch communication channels when needed. However, as the number of nodes using the same channel increases, packet collisions occur more frequently, thereby degrading response performance. On the other hand, frequent channel switching inevitably increases channel switching delays. To simultaneously reduce both packet collisions and channel switching delays, we have extended the average-channel-utilization-based channel switching (ACS) scheme, discussed in our previous work on single-hop communication in a way that allows it to provide efficient performance in multi-hop communication. In this paper, based on simulations, we show how our scheme can improve the delivery ratio performance by approximately 20%. |

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.
