在本文中，我们处理无线传感器网络的移动性管理，我们专注于第一阶段的切换过程，这是有关的力学测量的重要参数和启动（触发）切换决策过程。我们引入了一系列的指标，可能会被用于触发切换，我们专注于两个容易找到的本地值，即接收信号强度指标（RSSI）和本地链路损耗。我们调查这些指标的能力，提供正确的触发器的决策过程中，考虑到不同的阈值，平均方法，平均窗口，和滞后余量。我们评估的性能的不同的指标和方法，不仅使用所产生的端到端的数据包丢失，切换触发器，最终执行的切换，和切换成功率，但也使用新的概念的时间触发。我们的评估提供了一个独特的洞察机制的切换触发和决策阶段。
In this paper, we deal with mobility management for wireless sensor networks and we focus on the first phase of a handoff procedure which is concerned with the mechanics of measuring important parameters and initiating (triggering) the handoff decision process. We introduce a range of metrics that could potentially be used in triggering a handoff and we focus on two easy-to-find local values, namely the Received Signal Strength Indicator (RSSI) and the Local Link Loss. We investigate these metrics on their ability to provide correct triggers for the decision process, taking into account different threshold values, averaging methods, averaging windows, and hysteresis margins. We evaluate the performance of the different metrics and methods using not only the resulting end-to-end packet loss, the handoff triggers, the eventual handoffs performed, and the handoff success rate, but also using the new concept of on-time triggering. Our evaluation provides a unique insight into the mechanics of the handoff trigger and decision phases.
