摘要： 提出一种监视节点基于事件触发机制的自适应选择算法(ETBAS)，引入监视节点的监视状态，通过事件触发使非监视节点进入唤醒状态进行入侵检测，或使监视节点进入睡眠状态停止入侵检测。触发事件包括相邻节点的推选、节点能源低于某个阈值、网络拓扑结构的变化等。ETBAS具有自适应性，无论监视节点离开网络还是新节点进入网络，通过与相邻节点的信息交互，都能实现局部网络监视节点的自动更新。

Abstract: This paper proposes an Event Triggering Based Adaptive Selection(ETBAS) algorithm of monitoring nodes, which introduces the mechanism of monitoring states and the method of event triggering. Triggering events, for example, a node is voted to be a monitoring node by its neighbors, the battery power of a monitoring node consumes to a threshold, or the networks topology changes, can awaken a non-monitoring node, or make a monitoring node fall sleep. The ETBAS is adjusted to the dynamic changing topology of Ad Hoc networks, whether a monitoring node leaves or a new node joins, its neighbors will be informed, and exchange battery power information to automatically re-choose new monitoring nodes in local network.

Key words: Ad Hoc networks, monitoring nodes, event triggering, monitoring states, adaptive selection
