基于消息侦听的高效快速发布／订阅路由算法
Fast and efficient publish/subscribe routing algorithm based on message listening
摘要
Abstract
To reduce the time delay and redundancy control overhead in the message forwarding be‐tween Hills in density driven publish/subscribe routing algorithm in mobile Ad‐Hoc network (MANET) ,a fast and efficient publish/subscribe routing algorithm based on message listening , FEPM L (fast and efficient publish/subscribe routing algorithm based on message listening )‐Pub/Sub , was proposed . A bidirectional transmission path between adjacent Hill was quickly established through the edge node listens for neighbor Hill ,and thus the efficiency of content matching was im‐proved .The heartbeat message piggybacked information of edge status to the Hilltop node ,then Hill‐top node choosed to avoid of forwarding message to edge state Hill ,and messages of turn‐back trans‐mission was avoided accordingly .In addition ,the protocol compressed message header fields ,thus re‐duced the cost .Also ,simulation results show that FEPM L can effectively decrease the overhead of data forwarding ,and reach a rapidly matching between published messages and subscribed nodes ,and also reduce the average end‐to‐end delay ,as compared to the existing classic algorithms .关键词
