In our project, we design middleware services for emergency and rescue scenarios in sparse mobile ad-hoc networks (SMANETs). One of these services is a distributed event notification service (DENS) for asynchronous communication. The DENS architecture allows several subscription languages for different kinds of subscriptions. To support complex subscriptions, we use a data stream management system (DSMS) for filtering of the data streams and matching of filtered events and subscriptions. We have designed a simple rescue scenario to investigate the possibilities of using a DSMS together with the DENS middleware layer. In this paper we discuss the design of our implementation and first experimental results of our ongoing work
