Environment queries: Service Discovery For Open Mobile Systems
Frederik Geerts · 2006
The proliferation of mobile devices and of the open mobile networks they bring forth, complicates the advertisement and discovery of services. The hardware characteristics of such mobile networks issue severe consequences for software development. In response to these consequences the Ambient-Oriented Programming paradigm was introduced. Service discovery protocols for open mobile networks must adhere to the same hardware characteristics. The current state-of-the-art protocols fail to cope with these restrictions. This led to the identification of a number of criteria to which an Ambient-Oriented service discovery protocol must comply with. The most crucial of those criteria is: rich service descriptions. This dissertation attempts to resolve the absence of rich service descriptions. The solution we propose, is to enrich AmbientTalk in such a way that it can describe services in terms of logic. A logic programming language is chosen as a service description language, because this makes reasoning about
