Currently the functionality of the PRC-999K radio that is widely used in Korean Army is half-duplex and the broadcasting system that all subscribers have to listen when one subscriber speaks in time. Radio data communication system configures peer-to-peer network between command post and network members in military fire control system. And the system applies CSMA/CA(Carrier Sense Multiple Access/Collision Avoidance) technique to avoid data collision. Such a data transmitting/receiving time could be reduced by allocating address in serial order to each network members. By doing that, command post need to broadcast data only one time and assigned members will reply in order without data collision. This paper provides such a protocol and algorithm.

The PRC-999K radio widely used in Korean Army is half-duplex and also has the broadcasting radio wave character that all subscribers listen when one subscriber speaks in time. The radio data communication system configures a 1:1 unicast network between a command post and network members in a military fire control system. The system also applies CSMA/CA technique to avoid data collision and additionally applies SDLC protocol for efficiency and fast communication. This paper shows that allocating address to network members in serial order can reduce data transmitting/receiving time, and thereby a command post needs to broadcast data only one time and the assigned members can reply in order without data collision. It is validated through an experimental test.
