Efficient information sharing is very important for emergency and rescue operations. Mobile Ad-Hoc Networks (MANETs) are often the only network environment for such operations. We have developed the MIDAS Data Space (MDS) to transparently share information among rescue applications in such environments. To achieve the required level of availability for important information, MDS performs optimistic replication. The problems caused by optimistic replication, like consistency management, are not solved by standard solutions; instead we employ tailor-made solutions for emergency and rescue applications.

“…In addition, middleware support has to be present to facilitate efficient application development for this type of infrastructure. In the Ad-Hoc InfoWare project [9], we are addressing these needs by developing middleware services for information sharing. The core building blocks of these services are knowledge management, a local and a distributed event notification service, resource management, and security and privacy management.…”

Development of applications and protocols for mobile ad-hoc networks has always been a challenge. Specific characteristics such as frequent topology changes due to nodes moving around, popping up or being turned off, need to be considered from the earliest stages of development. Since testing and evaluation using genuine wireless devices is both expensive and highly impractical, other tools need to be used in the development phase. Simulators give a very detailed model of lower layers' behaviors, but code often needs to be completely rewritten in order to be used on actual physical devices. Emulators present a trade-off between real test beds and simulators, providing a virtual wireless network at the lowest layers, and yet allowing real code to be run on the higher layers. In this paper, we present such an emulation platform, called NEMAN, that allows us to run a virtual wireless network of hundreds of nodes on a single end-user machine. NEMAN has shown to be an important and very useful tool during development of different applications and protocols for our project, including a key management protocol and a distributed event notification service.

“…In the Ad-Hoc InfoWare project [8], we are developing middleware services for emergency and rescue applications, like command and control, dispatching of resources, and remote patient monitoring. Since emergency and rescue operations are typically performed in environments without any or only a very rudimentary amount of existing infrastructure, mobile ad-hoc networks are used for communication.…”

The subscription language is an important design decision for distributed event notification services (DENS). In order to minimize resource consumption and enable applications to use rich and complex subscription languages only when they are really needed, we have developed a DENS that separates the concerns of delivering subscriptions and notifications from the subscription specification and event filtering, i.e., the subscription language. To resolve the conflict between subscription language independence in DENS and a strict decoupling of publishers and subscribers through the DENS, we request that for each new subscription language three language specific plug-ins are provided. In this paper, we present the technical details of this solution and describe our proof-of-concept implementation that supports a simple attribute-value based subscription language and a fuzzy concept-based language.
