무선 LAN은 실시간 버스티 트래픽(예: 음성 또는 비디오) 및 데이터 트래픽을 제공할 수 있는 기능을 갖춘 멀티미디어 환경에서 완전히 분산된 사용자를 구현하는 데 사용되었습니다. 본 논문에서는 CSMA/CA(충돌 방지를 통한 비영구 반송파 감지 다중 접속) 프로토콜을 사용하여 멀티미디어 통신을 지원하는 무선 LAN의 성능에 대한 새로운 현실적이고 상세한 시스템 모델과 새로운 효과적인 분석을 제시합니다. 이 CSMA/CA 모델에서는 전송할 패킷이 있는 사용자가 처음에 충돌 회피 기간 내에 임의의 간격으로 일부 펄스 신호를 보낸 후 패킷을 전송하여 클리어 채널을 확인합니다. 시스템 모델은 공통 채널을 효율적으로 공유하기 위해 유한한 수의 사용자로 구성됩니다. 각 사용자는 음성 트래픽과 데이터 트래픽 모두의 소스가 될 수 있습니다. 시간 축은 슬롯으로 구성되며 프레임은 많은 수의 슬롯을 가지며 충돌 방지 기간과 패킷 전송 기간의 두 부분으로 구성됩니다. 이산시간 Markov 프로세스는 시스템 작동을 모델링하는 데 사용됩니다. 프레임의 슬롯 수는 충돌 회피 기간과 패킷 전송 기간의 선택된 길이에 따라 임의적일 수 있습니다. 다양한 패킷 생성 속도에 대한 채널 활용도 및 평균 패킷 지연 측면에서 수치 결과가 표시됩니다. 이는 충돌 회피 기간과 전송 기간 사이의 비율과 펄스 전송 확률의 적절한 선택을 통해 네트워크 성능을 향상시킬 수 있음을 나타냅니다.

Abstract: Wireless LANs have been used for realizing fully-distributed users in a multimedia environment that has the ability to provide real-time bursty traffic (such as voice or video) and data traffic. In this paper, we present a new realistic and detailed system model and a new effective analysis for the performance of wireless LANs which support multimedia communication with non-persistent carrier sense multiple access with collision avoidance (CSMA/CA) protocol. In this CSMA/CA model, a user with a packet ready to transmit initially sends some pulse signals with random intervals within a collision avoidance period before transmitting the packet to verify a clear channel. The system model consists of a finite number of users to efficiently share a common channel. Each user can be a source of both voice traffic and data traffic. The time axis is slotted, and a frame has a large number of slots and includes two parts: the collision avoidance period and the packet transmission period. A discrete-time Markov process is used to model the system operation. The number of slots in a frame can be arbitrary, dependent on the chosen lengths of the collision avoidance period and packet transmission period. Numerical results are shown in terms of channel utilization and average packet delay for different packet generation rates. They indicate that the network performance can be improved by adequate choice of ratios between the collision avoidance period and transmission period, and the pulse transmission probability.
