| Abstract | In order to reduce energy wastefully consumed by WiFi device, Radio-On-Demand Networks (ROD) has been proposed, which offers wireless access in an on-demand manner. Each WiFi device in ROD is equipped with a low-power wake-up receiver which is capable of detecting the length of frames observed over WiFi channels through envelope detection and on-off-keying (OOK) processing. Once the wake-up receiver detects the predefined set of length of WiFi frames included in the wake-up signal transmitted by the other WiFi device, it turns its main WiFi module on. The wake-up receiver extracts WiFi signals over all WiFi channels at 2.4 GHz band. On the other hand, a WiFi device, which tries to wake up the other device, selects a wake-up channel, a channel to transmit its wake-up signal. In this case, the receiver observes an envelope which is the combination of the wake-up signal and the interfering signals existing over all WiFi channels. Here, how to select the wake-up channel is a key issue when the degree of interference is different among multiple WiFi channels. In this paper, with different degree of interference in each channel, we evaluate the impact of wake-up channel selection on the wake-up success probability of WiFi device. Besides simulations results, we also present experimental results which are obtained with our developed prototype of wake-up receiver. |

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.
