The Analysis of Publish/Subscribe Systems over Mobile Wireless Ad Hoc Networks

In this work, we analyze the publish/subscribe distributed system paradigm over mobile ad hoc networks with respect to the performance and the impact of different mobility speeds and patterns of all participants in urban and high-way scenarios. In order to handle mobility, our publish/subscribe framework relies on light-weight publish/subscribe brokers, which are chosen in a topic-driven fashion. With the option of geographic location and waypoint information, we discuss several publish/subscribe variants and analyze their advantages/disadvantages when applied in different mobility environment. Via simulations, we measure quality of service in terms of delivery ratio and message delay achieved by such different publish/subscribe schemes over different scenarios and mobility models.
