一种无线自组网故障检测算法
A Failure Detection Algorithm for Ad Hoc Network
摘要
Abstract
A failure detection architecture and algorithm based on clustering are proposed according to the topology of Ad Hoc networks. The active and the backup cluster manager are designated respectively. The exception detection function of the members is implemented by the selected redundancy cluster managers. The sending, monitoring, prediction and updating process of the heartbeat message are designed for fault detection. The updating method of the heartbeat prediction is added to fit the variable topology of Ad Hoc networks dynamically. Through the backup cluster manager and the exception data shared mechanisms among clusters,the system fault detection reliability is improved. The proposal is evaluated by the simulation. As a result, the proposed failure detection mechanism achieves a high accuracy, and is capable of the requirement of the top application design for the system reliability.关键词
