| Abstract | This paper proposes two energy-efficient standby mode algorithms in short-range one-to-one 60 GHz millimeter wave (mmWave) communications. Among the many usage scenarios for mmWave radio, file downloading from kiosk terminals or peer-to-peer sync service with portable terminals are of great interest. For these portable terminals, the power consumption of standby mode as well as connection setup time is important. Comparing the power consumption for a frame transmission with that for a frame reception in short-range one-to-one 60 GHz mmWave, the power consumption for a frame reception may become larger than that for a frame transmission. In this paper, two energy-efficient standby mode algorithms are proposed for one-to-one communications. In the proposed algorithms, each terminal operates based on Interval consisting of several Sub-intervals. One proposed algorithm (Prop1) is that a terminal transmits a connection request frame (CREQ) once at every Sub-interval and the other terminal waits for the CREQ during one Sub-interval per each Interval. Thus, Prop1 saves the power consumption for a CREQ transmission. The other proposed algorithm (Prop2) is that a terminal selects one Sub-interval randomly for each Interval and transmits CREQs repeatedly during that Sub-interval. The other terminal waits for a CREQ during this CREQ transmission period at every Sub-interval. Prop2 saves the power consumption for a CREQ reception. We evaluate the power consumption of standby mode and connection setup time for Prop1 and Prop2 by both numerical analysis and computer simulations. We compare these proposed algorithms under several ratio of the power consumption for transmission and reception. |

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.
