摘要： 在内容发布/订阅系统中，针对传统订阅重构算法存在订阅冲突等问题，提出一种适应移动Ad Hoc网络特点的事件重构算法。该算法扩展了订阅转发方法，将订阅重构消息转发范围限制在重构路径上，有效避免了订阅冲突，提高重构效率。实验结果表明，该算法缩短了订阅重构时间，且性能受网络规模影响较小。

Abstract: In content-based publish/subscribe, in view of subscription conflict and low efficiency in subscription reconfiguration, an algorithm that meets the features of mobile Ad Hoc network is proposed. The algorithm improves subscription forwarding method and forwards the message only on reconfiguration path, which avoids subscription conflict and improves efficiency. Experimental results show the algorithm decreases subscription reconfiguration time and its performance suffers little influence from network scale.

Key words: content-based Publish/Subscribe(P/S), subscription reconfiguration, mobile Ad Hoc network
