Semantic Sensor Net: an extensible framework

Existing approaches for sensor networks suffer from a number of critical drawbacks. First, homogeneous deployments have been commonly assumed, but in practice multiple deployments of sensor nets and heterogeneity of sensor networks are a serious problem. Second, existing approaches are very application-dependent and engineering-oriented. Third, there has been little standard available for WSNs. These drawbacks have significantly limited the further development of sensor networks. To overcome these critical drawbacks, we propose an extensive framework: Semantic Sensor Net (SSN). In brief, a semantic sensor net is a heterogeneous sensor network which enables dynamic tagging of semantic information to sensory data to allow more efficient and systematic monitoring and handling of the environmental dynamics to provide demanded services.
