In this paper, we introduce a novel multiple access scheme for aerial sensor networks employing adaptive antenna arrays with spatial reuse. Spatial reuse has been adopted to enable simultaneous data transmission among unmanned aerial vehicles in a context of spatial diversity. This work introduces two types of UAV: a single main actor UAV and multiple actor UAVs. Since these UAVs cooperatively perform...
In this paper, we propose an effective data gathering protocol in an air-to-ground communication network employing priority-based contention window adjustment scheme. The proposed protocol adopts a conventional CSMA/CA. An unmanned aerial vehicle is used as a relay sink to collect data from a ground wireless sensor network. In our scheme, we divide the coverage area of UAV's beacon signal into many...
This paper proposes the effective data gathering and energy efficient communication scheme for Wireless Sensor Networks employing Unmanned Aerial Vehicle. In this scheme, we minimize the number of redundant sensors communicating with UAV by assigning the sensors inside the coverage area of UAV's beacon signal into different priority groups. Once the priority segments, Circularly Optimized Frame Selection...
