摘要
EU FP6 ANGEL项目考虑在医疗应用中使用基于IEEE 802.15.4的无线传感器网络技术。在这类应用程序中发现的一些关键需求不被IEEE 802.15.4很好地支持。在本文中,我们在IEEE 802.15.4之上提出了一个包装层,该层添加了一种结合优先级队列和每包参数控制的机制,以提供(随机)服务差异化。本文描述了该机制的设计和实现,并给出了测试结果,证明了该机制的有效性。
The ANGEL IEEE 802.15.4 enhancement layer: Coupling priority queueing and service differentiation
The EU FP6 ANGEL project considers the usage of IEEE 802.15.4-based wireless sensor network technology in medical applications. Some key requirements found in this class of applications are not well supported by IEEE 802.15.4. In this paper we propose a wrapper layer on top of IEEE 802.15.4 that adds, amongst others, a mechanism combining priority queueing and per-packet parameter control to provide (stochastic) service differentiation. In this paper we describe the design and implementation of this mechanism and present measurement results, showing its effectiveness.
