Logical Sensor Network : An Abstraction of Sensor Data Processing over Multidomain Sensor Network

Abstract EN

This paper focuses on a sensor network virtualization over multidomain sensor network and proposes an abstraction called “logical sensor network (LSN)” for sensor data processing.

In the proposed abstraction, processing is a directed acyclic graph that consists of nodes and streams, which represents a small data processor and communication rules between them, respectively.

We have added a notion of a trigger to this graph.

A trigger represents a timing of the process execution.

We have implemented the middleware named LSN-Middle to run a virtualized sensor network and proved its feasibility.
