Abstract

In this paper, applications that require low-speed data rate on personal area network to operate the Land Warrior system is proposed. These applications can refer to WSN(wireless sensor network) technology. However, this technology is not suitable to support various data transmission rate. A suitable CSMA/CA algorithm for Land Warrior System in order to solve these existing system problems is proposed. The proposed algorithm is designed to be variable CSMA/CA algorithm parameter, depending on data rate. For the evaluation of Land Warrior system model and CSMA/CA algorithm, we used Castalia. As a result of the simulation, it is found that the proposed system model can not only relieve loads of data processing, but also probability of collision was decreased.

본 논문에서는 개인 영역의 저속 데이터 전송률을 요구하는 응용을 운용하기 위한 미래병사체계의 시스템 모델을 제안한다. 저속 데이터 전송률을 요구하는 응용들은 기존의 무선 센서 네트워크기술을 참조할 수 있지만, 상이한 데이터 전송률을 지원하기에 적합하지 않다. 이러한 기존 시스템의 문제점들을 해결하가 위하여 미래병사체계에 적합한 CSMA/CA 알고리즘을 제안하였다. 제안한 알고리즘은 데이터 전송률에 기반을 두어 CSMA/CA 알고리즘의 파라미터를 가변하도록 설계되었다. 제안한 시스템 모델 및 알고리즘은 Castalia를 이용하여 시뮬레이션 하였으며, 시뮬레이션 결과 제안한 시스템 모델이 기존 방식과 비교하여 데이터 처리량이 개선되고, 충돌 확률이 감소함을 확인할 수 있었다.
