笔者用跳时多址接入,解决超宽带自组网MAC层的实时业务QoS问题。由于超宽带的接入延迟很大,这里提出在节点中将转发业务与本地业务按实时性要求分类,优先级高的先发,优先级低的后发,这样能更好的保证实时业务不会受到接入延迟的影响,并且允许各种业务交叉传输,解决了802.11e中的QoS机制造成的低优先级业务“饿死”的现象。仿真表明:节点中的业务在满足公平接入信道方面取得了很好的效果。 I use multiple access when jumping, to solve the MAC layer of ultra-wideband ad hoc network QoS real-time issues. Due to the large access delay of UWB, we propose to classify the forwarding and local services according to real-time requirements in the node. The prioritized high priority and low priority post issuance ensure better real-time service Will be affected by access delay, and allow a variety of business cross-transmission, to solve the low priority business caused by the QoS mechanism in 802.11e “starved to death ” phenomenon. The simulation shows that the service in the node has achieved good effect in meeting the fair access channel.
