To this end, the ROK military is developing a Korean Tactical Data Link (Link-K) in two stages: Basic and Completion types. Currently, the basic type of the Link-K has a limitations for supporting Mission Group(MG)s, such as to share unnecessary information and inefficient routing, because all RICCs simply broadcasts the same information in the basic type of the Link-K. In this paper, we propose a Zone-based Wireless Link-K network structure and a routing algorithm. To improve the effectiveness of the proposed routing algorithm, we have studied a filtering method that adjusts the message data according to the priority of the message and a method of controlling the load of the network. In order to evaluate the performance of the proposed scheme, it is proved that it is effective to support the mission task group compared with the existing wireless Link-K routing algorithm according to the operational scenario situation.

As modern warfare has changed into network centered, the ability to share situational awareness among allies become a core competency for performing operational missions. In an airborne environment, it uses a tactical data link such as Link-16 for shared situational awareness. There exist problems when it shares situational awareness over the existing data link that can not allocate slots dynamically or that can not change the number of a slot to be allocated. In addition, there was a problem that can not share this failure so that failed to improves situation awareness because of finite time slot resources. In this paper, we accommodate dynamic slot allocation and changes of slot allocation with mixed structure of TDMA (time division multiple access) and random access. We propose a technique that can be used when available slots are exhausted, and a load balancing method to prevent slot allocation delay when slot requesting or message sending is concentrated on a single subframe.

As the trend of future war has been changed to network centric warfare, tactical data link should be needed for fast and accurate situation awareness. Nowadays, Korean air force conducts military operations by using aircrafts equipped with Link-16. The Link-16 can conduct multiple mission at the same time because it supports multi-net capability. Due to lack of frequency resource, the way to share the frequency with other systems has been studied and using L band with radar is considered as one of the candidates bands. However, the data link can be affected by the interference from radars when it shares the L-band because the L-band in Korea is already assigned to long-range detection radars. In this paper, we evaluate operational possibilities of tactical data link in the L-band based on Link-16.
