Abstract

In this paper, a dynamic contention periods based on the collision group(DCCG) algorithm is proposed for collision resolution in the IEEE 802.16 broadband wireless access network. The DCCG algorithm determines the contention periods according to the a number of collided slot and collided requests to the base station(BS). The DCCG algorithm is useful to improve the performance of throughput and system delay characteristic than binary backoff algorithm.

본 논문은 IEEE 802.16 광대역 무선 액세스 망을 위한 새로운 충돌 감소 방안으로 DCCG 알고리즘을 제안하였다. 이 알고리즘은 채널 경쟁 후 충돌이 발생한 슬롯 수와 가입자의 충돌 횟수에 따라서 상향링크의 자원요청 슬롯 구간을 결정한다. 그 결과 제안한 DCCG 알고리즘은 기존 Binary Back-off 알고리즘보다 처리율이 증가하였고 지연시간이 감소하였다.
