This paper aims at providing a mapping schema for mission and devicein distributed sensor network(DSN)domain from the semantic perspective,which is very helpful to machine-interpreting and autonomous situation awareness.The mapping schema includes a shared specification for the mission requirements and device capabilities,as well as the relationships between these elements.The specification includesfour collections thatare used to define:interest,target,capability and status.Based on the mapping schema,a ontological knowledge base is constructed,through which the alternative solutions can be generated.
