在这篇文章中，我们提出了BurstProbe，一种新的技术，用于精确测量无线传感器网络中的链路突发，用于时间关键型数据传输。测量依赖于嵌入在传输调度中的共享探测时隙，节点使用这些时隙来评估随时间推移的链路突发。获取的链路突发信息可以存储在节点的闪存中，并在发生错过最后期限时用于诊断传输问题。因此，以分布式方式实现了准确的诊断，而无需将丰富的测量数据传输到中央采集点的开销。出于评估的目的，我们在GinMAC无线传感器网络协议中实现了BurstProbe，我们能够证明它是一个调试时间关键型数据传输的准确工具。此外，我们还对实施BurstProbe的成本进行了分析，并调查了其有效性。
In this paper we presentBurstProbe, a new technique to accurately measure link burstiness in a wireless sensor network employed for time-critical data delivery. Measurement relies on shared probing slots that are embedded in the transmission schedule and used by nodes to assess link burstiness over time. The acquired link burstiness information can be stored in the node’s flash memory and relied upon to diagnose transmission problems when missed deadlines occur. Thus, accurate diagnosis is achieved in a distributed manner and without the overhead of transmitting rich measurement data to a central collection point. For the purpose of evaluation we have implemented BurstProbe in the GinMAC WSN protocol and we are able to demonstrate it is an accurate tool to debug time-critical data delivery. In addition, we analyze the cost of implementing BurstProbe and investigate its effectiveness.
