In this paper, we compare two peer-to-peer implementation strategies for persistent publications in location-based publish/subscribe. Both approaches use a scoped flooding algorithm to effectively disseminate data through the network – the first naive alternative propagates only published events, while the second smarter approach disseminates subscriptions during a warm up phase and then routes matching publications with a multisend communication primitive. We show in preliminary performance evaluations that depending on the applicative scenario, the cost of the warm up phase cannot be covered and the seemingly naive approach can outperform the smart one.
