碩士 === 國立暨南國際大學 === 電機工程學系 === 95 === In Ad Hoc wireless network each station can work well by using Distributed Coordination Function(DCF) mechanism in Medium Access Control(MAC)layer, but the DCF can not support quality-of-service (QoS) . Therefore , this paper proposes the stateless wireless Ad Hoc Network(SWAN) mechanism to support service differentiation . In this way we can achieve the expected QoS when the network operates. We study the distributed coordination function and stateless wireless Ad Hoc Network(SWAN) in this thesis. By comparing the DCF and SWAN mechanisms and with the simulation results, we found that even the traffic load is high, the SWAN can effectively reduce the delay and increase the throughput. We also found from simulation results that contention window (CW) will significantly affect the network performance.
