| Abstract | This paper presents a Multi-Frequency Time Division Multiple Access (MF-TDMA) scheme for long-packet and energy-constraint Radio Frequency Identification (RFID) sensing applications. The scheme takes advantages of both multiple transmission channels and scheduled time slots for high throughput and low latency. In addition, a dedicated channel is allocated to provide synchronization and coordination of the entire sensor tags to maximize the efficiency by re-using the scheduled slots. Meanwhile, an adaptive synchronization cycle is applied on each tag to minimize the probability of packets collision due to clock skew between sensor tags. Moreover, slots and channels reset mechanism is also suggested to cope with interference caused by other co-exist networks such as Wi-Fi. The performance analysis of the proposed MF-TDMA scheme shows that by employing 3 transmission channels it can achieve up to 3.3 times throughput compared to single channel TDMA. An optimal point of 90% packets delivery ratio can be obtained under the same experimental condition. |

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.
