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

In this work, we analyze the publishlsubscribe dis-tributed system paradigm over mobile ad hoc networks with respect to the performance and the impact of differ-ent mobility speeds and patterns of all participants in ur-ban and high-way scenarios. In order to handle mobil-ity, our publishlsubscribe framework relies on light-weight publishlsubscribe brokers, which are chosen in a topic-drivenfashion. With the option ofgeographic location and waypoint information, we discuss severalpublishlsubscribe variants and analyze their advantagesldisadvantages when applied in different mobility environment. Via simulations, we measure quality ofservice in terms ofdelivery ratio and message delay achieved by such differentpublishlsubscribe schemes over different scenarios and mobility models.
