摘要:

IEEE 802.15.4支持用于无线个域网(WPAN)中的时间关键和延迟敏感的数据传输的保证时隙(GTS)分配机制。然而,不灵活的先到先服务的GTS分配策略和被动的释放机制显着降低网络效率。在本文中,我们提出了一个自适应和实时的【形】GTS分配方案(ART-GAS),提供不同的优先级的设备,这保证了时间敏感和高流量的设备的数据传输的差异化服务。提高了基于IEEE 802.15.4的PAN的带宽利用率。仿真结果表明,我们的ART-GAS算法显着优于现有的GTS机制中规定的IEEE 802.15.4。

英文摘要:

IEEE 802.15.4 supports a Guaranteed Time Slot (GTS) allocation mechanism for time-critical and delay-sensitive data transmissions in Wireless Personal Area Networks (WPANs). However, the inflexible first-come-first-served GTS allocation policy and the passive deallocation mechanism significantly reduce network efficiency. In this paper, we propose an Adaptive and Real-Time GTS Allocation Scheme (ART-GAS) to provide differentiated services for devices with different priorities, which guarantees data transmissions for time-sensitive and high-traffic devices. The bandwidth utilization in IEEE 802.15.4-based PAN is improved. Simulation results show that our ART-GAS algorithm significantly outperforms the existing GTS mechanism specified in IEEE 802.15.4.
