Recently, many companies try to offer various services using drones. Especially, the drone delivery system is a good example. However, the drone delivery service has some problems since the heavy parcels flies over the people walking down streets, so many things must be considered such as dropping mails by collision of drones. To resolve the problem, in this paper, a inter-drone network communication will be used to design the topology and to simulate in the Opnet simulator for the performance evaluation. Additionally, the topology with random mobility of trajectory of drones is also designed and simulated for the result.

4차 산업혁명의 핵심으로 떠오르고 있는 드론 산업의 성장속도가 점차 빨라짐에 따라 드론 활용도가 점차 높아지고 있다. 물류시장의 화두는 신속한 배송이지만 기존 택배 및 우편물 등을 배송하기에는 도로의 교통상황에 따라 시간이 많이 들고 인력비와 수송비등 자원이 많이 필요하다. 본 논문은 기존의 택배 시스템에서 사람이 직접 이동해서 물건을 전달하는 방식이 아니라 드론을 이용하여 효과적으로 배송할 수 있는 방법을 제안하고자 한다. 드론을 원하는 목적지까지 보내는 과정에서 발생하는 여러 돌발 상황을 대처할 수 있도록 GPS 및 아두이노기반의 여러 센서들을 이용하여 안정적으로 제어하는 것이 본 논문의 목적이다. 그 외 문자알림 서비스를 이용하여 택배의 실시간 위치를 알 수 있게 하고 도착알림 등을 받게 하여 편리성을 높이는데 역점을 두었다.

Despite the recent economic difficulties, the on-line market is overtaking the off-line market. Since US Amazon CEO Jeff Bezos mentioned that a delivery service using drones is possible, it has been creating new perspectives and values that have never been seen before. Drones are being used in various fields. Among them, the delivery service using drones will be the future growth engine of Korea in cooperation with the 4th industrial revolution. However, as drones are put into practical use, problems such as human life and property damage and personal information protection due to public collisions or falls are expected. The practical use of future drones is inevitable, not optional. As a method for commercialization of drones, first, securing safety through drone use and securing a national certification system, which is the minimum standard system for drone safety, and second, securing various infrastructures by activating drone use, and third, aviation regulations and personal information protection, etc. It needs to be supplemented in terms of laws and regulations.

The drone delivery service as a new important business is emerging worldwide. American DHL parcel service is already running the delivery business using drones, and the Google, Amazon, and china's Alibaba, Baidu are also preparing for the same business. However, there are some problems in security and safety since the heavy parcels flies over the people walking down streets, so many things must be considered. The problems can be solved by communicating among drones to avoid collision. Therefore, the efficient network performance is essential, and to resolve the problem, in this paper, an efficient routing protocol is suggested by the Opnet simulator. The drone intercommunication network of MANET is designed and simulated for the efficient routing protocol.

해외에서는 드론을 이용한 배달 서비스가 상용화되는 추세이지만, 한국에서는 여러 가지 한계점에 의해 서비스 개발이 침체하여 있는 상황이다. 이 문제를 해결하기 위해 창문에 카메라를 장착하여 드론이 촬영되고 있는 영상을 리눅스 서버에 전송하고, 딥러닝과 이미지 프로세싱을 통해 드론을 검출하고 택배를 받을 수 있는 위치로 조정한다. 조정이 완료되면 창문 개방 후 택배를 받는다.

Drones are now widely used in civilian applications such as filming, leisure, agricultural control, monitoring, and the generation of 3D-spatial information, deviating only from military drones. In the field of logistics, prototypes are emerging in the area of logistics transportation, and to develop a future transportation service under the name of a drone tax, each country is introducing its first flight results using its own unique drones. In this paper, we review the domestic and overseas trends of drone delivery service technology, which requires various capabilities such as automatic flight, and review the related core technologies. We then propose the flight capability and road map of a drone delivery service according to the detailed conditions such as the flight area, visibility, and flight method. Additionally, in connection with the postal processing of the Korea Post Office, which would be a main demand for this type of service, we describe a method for realizing a drone delivery service based on the structure, scenario, and deployment of the drone delivery system.

In the era of the 4th industrial revolution, public libraries need a strategy for promoting intelligent library services in order to actively respond to changes in the external environment such as artificial intelligence. Therefore, in this study, based on the concept of artificial intelligence and analysis of domestic and foreign artificial intelligence related trends, policies, and cases, we proposed the future direction of introduction and development of artificial intelligence services in the library. Currently, the library operates a reference information service that automatically provides answers through the introduction of artificial intelligence technologies such as deep learning and natural language processing, and develops a big data-based AI book recommendation and automatic book inspection system to increase business utilization and provide customized services for users. Has been provided. In the field of companies and industries, regardless of domestic and overseas, we are developing and servicing technologies based on autonomous driving using artificial intelligence, personal customization, etc., and providing optimal results by self-learning information using deep learning. It is developed in the form of an equation. Accordingly, in the future, libraries will utilize artificial intelligence to recommend personalized books based on the user's usage records, recommend reading and culture programs, and introduce real-time delivery services through transport methods such as autonomous drones and cars in the case of book delivery service. Service development should be promoted.
