Abstract: In this article, we present our lightweight semantic publish/subscribe system µC-SemPS that is targeted towards wireless battery-powered embedded systems in ubiquitous computing environments. The key challenge that we address is the minimization of the overall energy consumption, which involves computational aspects for semantic subscription matching, and communication aspects for the delivery of the publications as events in a wireless network. Our pub/sub system relies on a compact mathematical
representation of the semantic subscriptions and publications, as well as fast semantic matching and routing
algorithms. From an energy efficiency point of view, it favors computation over the more expensive wireless
communication for the semantic matching and routing of events. When compared to more conventional pub/sub routing implementations, experimental results from network and energy simulations with MiXiM, an OMNeT++ modeling framework extension for wireless and mobile networks, show that our approach for routing semantic events significantly reduces energy consumption.
