空间目标定位是无线传感器网络研究中的一个常见问题。除了位置估计本身之外，无线通信是这样的系统内的中心方面。我们提出了一种新的HashSlot方法，用于在恒定和可预测的时间内将无线电数据包从多个源传输到一个共同的目的地。由于自组织，我们的方法不需要事先主动协调传感器节点之间，并提供了各种技术，如可选的服务质量水平，动态限制在运行时返回的信息的数量。因此，定位过程的精度和速度可以被调节，可以实现容错并且能量消耗将被降低。介绍了HashSlot方法的原理及其在一个真实的基于无线传感器网络的定位系统中的应用。
Localization of objects within space is a common problem in WSN research. Besides the location estimation itself, wireless communication is a central aspect within such systems. We present the novel HashSlot method for assured and collision-free transmission of radio packets from multiple sources to a common destination within a constant and predictable time. Due to self-organization, our approach needs no prior active coordination between sensor nodes and offers various techniques like selectable quality of service levels to dynamically limit the number of returned information during runtime. Thereby, precision and speed of the localization process can be adjusted, fault tolerance can be achieved and energy consumption will be reduced. This paper describes theory and application of the HashSlot method within a real WSN based localization system.
