对抗WLAN系统OBSS频谱效率不足的MAC层设计
MAC layer approaches to mitigating the spectrum underutilization due to the overlapping BSS problem in WLAN
摘要
Abstract
Considering the OBSS-induced spectrum underutilization problem in Wireless Local Area Networks(WLAN),two complementary contention-based Media Access Control(MAC) layer schemes are proposed by setting up a virtual-primary channel for contention.The proposed transmission opportunity(TXOP) scheme is designed for transmitting long data packets,which is suitable for applications requiring high throughputs.In contrast,the multi-contention(MC) scheme is designed for transmitting short data packets,which is suitable for applications requiring short delays.By efficiently exploiting the OBSS-induced underutilized spectrum,simulation results verify the fact that the proposed TXOP scheme can increase the throughput greatly and the proposed MC scheme can reduce the delay for short data packets significantly.关键词
