| Abstract | There are advantages to retrieve information from the Wireless Sensor Network (WSN) for UAVs (Unmanned Aerial Vehicles). However, the UAV-WSN system has some differences with conventional WSN system. So it is important to design an appropriate scheme to control the transmission in a UAV-WSN system. In this paper we proposed a protocol called A-OAloha (Adaptive-Opportunistic Aloha) for UAV-UAV-WSN system to guarantee its efficiency. This protocol is based on a cross-layer design and is designed with the consideration of the distribution of the successful sensors, energy consumption and the transmission efficiency. For the distribution of the successful sensors, we design a mechanism based on the priority to make the distribution more uniform and the priority could be adaptively changed. For the consideration of energy-efficiency we choose to use the method that make the sensors go into sleep when they do not need to send data until a beacon signal from the UAV is received to transmit data. For the transmission efficiency we added a communication stage in every interval based on the O-Aloha scheme to enlarge the throughput under an acceptable system Bit Error Rate (BER). |

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.
