The proposed architecture conforms to 3GPP LTE (Long Term Evolution) standards supporting resource schedule to meet QoS (Quality of Service) requirements for both transmission directions of UL (Up Link) and DL (Down Link) between eNodeB (i.e., LTE base station) and UEs (i.e., LTE terminal devices). Furthermore, the thesis presents a design of relay function for multi-UAV communication for military purposes and evaluates its performance in an implemented simulation environment. The proposed design of relay function is based on the popular and commonly used LTE technology. Accordingly, the implementation can be low-cost and performance-efficient. Bandwidth requirements are classified into two types of GT (Guaranteed) and BE (Best Effort) by the implemented scheduler. Accordingly, transmission of control data using GT bandwidth has a higher scheduling priority than that of multimedia message (e.g., image, picture or video stream) with BE bandwidth. As such, bandwidth allocation for control data can be adequate to avoid UAV crash due to missing packet of control data. Consequently, by utilizing the proposed relay function, UAVs can be dispatched to areas that cannot reach before to monitor environment and collect information, and then transmit data messages backward to a ground console in real time. |
