Resource Management for Mobile Publish/Subscribe Systems

Distributed publish/subscribe middleware insures the necessary decoupling, expressiveness, and scalability for modern distributed applications. Unfortunately, the performance of this middleware is usually degraded in the presence of highly mobile scenarios. In this paper, we tackle the problem of mobility in publish/subscribe by exploiting a predictive scheme. We investigate the adequacy of our approach using a prototype implementation with respect to different scenarios. The experimental results show that our approach reduces the caching cost, the propagation cost and the network load. It also achieves better results in terms of overhead.
