A Review of Semantic Sensor Technologies in Internet of Things Architectures

Table 2

Comparison of middleware technologies based on semantic (SEM), computational (COMP), and storage demands (STORAGE) and how they support the development of distributed (DIST) and universal (UNIVERSAL) applications and how they are widespread (SPREAD).
