Abstract:
In the situation where various defense robot systems are developed and operated, wireless network is an indispensable element to remotely control unmanned robots. However, when each defense robot is operated on the basis of wireless communication, the available frequency resources per robot are limited. At this point, if multiple robot operations are increased and the number of robots participating in them increased exponentially, a serious shortage of available frequencies is expected. Therefore, we propose a dynamic allocation of frequency resources as the bottom-up type approach to overcome this problem. More specifically, we implemented a bandwidth allocation scheme according to the priority change of each end node. We also show the validity and efficiency of this method through the related experimental results.
