군 차세대 Ad-hoc 네트워크에서의 TPMA-CCR 프로토콜의 네트워크 최적화

Abstract

The Ad-hoc protocol has been studied and developed in the field of the military communication for securing the seamless communication among mobile units. In the TICN (Tactical Information & Communication Network), the next generation military communication system of Korea Military, the TMMR(Tactical Multiband Multirole Radio) can be seen as a part of these efforts to utilize the advantage of Ad-hoc networks for the communication of small battle units. Therefore, in our previous paper [4], TPMA-CCR (Three Phase Multiple Access-Continual Contention Resolution), which is the MAC protocol suitable for Ad-hoc networks, was proposed and proved with mathematical analysis that it has better performance than the existing TPMA(Three Phase Multiple Access) protocol in terms of throughput. However, when designing the new protocol, not only the performance must be considered, but also the network optimization must be considered in the aspect of its feasibility and simplicity. So, in this paper, we describe the methods of the network optimization of TPMA-CCR and TPMA, and compare those method in terms of their feasibility and simplicity with simulation and mathematical analysis.
