【摘要】 对于现今飞速发展的无线局域网,提出一种新的分布式资源预留算法DART,其关键部分在于实时性应用中分布式端到端的时间片分配DEA(Distributed end-to-end Allocation of time slot),并添加干涉保护,对于损坏的预留数据包进行修复,以及释放无用预留资源。模拟试验结果表明DART具有更低的时间延迟和较为固定的传输时间,而且每个预留数据流的传输时间基本上一致。更多还原

【Abstract】 With the fast development of WLANS,a new distributed end-to-end reservation protocol(DART) is presented.The key features of the new protocol are distributed end-to-end allocation of time slot,interference protection,repair of broken reservations and release of disu-sed reservations.A simulation-based performance study shows that DART has a low,non-varying delay and a constant throughput for each reserved flow.更多还原
