Workflow support for wireless sensor and actor networks
Pablo Ezequiel Guerrero, Daniel Jacobi, Alejandro Buchmann · 2007
As initial challenges of wireless sensor and actor networks (WSANs) are overcome, their application possibilities evolve. For these applications to move mainstream, efficient programming methods are required which can be used by domain experts. So far, the question of how can WSANs be efficiently programmed remains unanswered. In this paper we examine proposed middleware approaches, and show that they have focused on data extraction rather than in-network actuation. We thus propose the usage of workflows as a means to define the logic that orchestrates the network activity, and introduce a language to express WSAN interactions. At this time, a concrete system is not given, but the paper discusses the relevant aspects towards one, and poses many questions for future research.
