Location Information Sharing with Multi Token Circulation in Flying Ad Hoc Networks

Communication is an important problem in Multi Unmanned Air Vehicle (UAV) systems. Flying Ad Hoc Network (FANET) structure provides a solution to communication problem of multi UAVs but in FANET structure, UAVs need to know location information of other UAVs to provide secure flight. For this reason, Location Information Sharing (LIS) is the most important challenges in FANETs. Token circulation schema is one of the solution method for LIS. In this method, the exchange of location information between UAVs is performed by circulating a token in FANET. In the literature, token circulation is handled to provide code distribution and in these studies only one token is used for code delivery with the limited number of UAVs. However, location information is much longer than the code delivery information. Therefore, LIS with token circulation takes more time than the code delivery. In addition to this if a large number of UAVs are found in FANET, size of the token will increase and this situation also cause the more delay for token circulation. The number of UAVs increases, the LIS with a single token circulation in FANET will take longer time. In this case seamless flight is not be possible in multi UAV systems. In order to achieve LIS with minimum delay, it is planned to increase the number of UAVs, and the number of tokens circulating in the network simultaneously. The aim of this study is to provide LIS with multi token circulation in FANETs.
