Data-logging and supervisory control in wireless sensor networks
2009
International Journal of Sensor Networks (IJSNet)
Preserved Fulltext
The DEC is responsible for generating rule-based tasks in order to address information-centric issues such as data-logging, alarm & event reporting and security. ...
This paper proposes a data-logging & supervisory control architecture to manage the information gathered by the WSN and make decisions based on this information. ...
Finally, data security requires restricting control of the DEC from unauthorized users. The DSC sets up security levels of security such as administrator, operator, guest etc. ...

In this work, we address these problems and reduce the required block size to Ω(log 4 N ). We remove most of the homomorphic multiplications while maintaining O(1) communication complexity. ...
With z ∈ Θ(λ), λ ∈ ω(log N ) and L ∈ Θ(log N ), we achieve B ∈ Ω(λ · [log N · log λ + γ]). In practice, γ ∈ O(λ 3 ), so γ dominates log N · log λ. Therefore, block size B is B ∈ Ω(γλ). ...
