Abstract: Highlights•Novel algorithms for geographically distributed complex event processing.•Minimize communication and monetary costs given QoS constraints.•Optimal, greedy and heuristic algorithms are proposed.•At a systems level, we explain how CEP engines can easily support our algorithms.•Experimental evaluation, using mainly real datasets and network topologies.
