Cloud-Assisted On-Sensor Observation Classification in Latency-Impeded IoT Systems
Separated nets in Euclidean space and Jacobians of biLipschitz maps
We show that there are separated nets in the Euclidean plane which are not
biLipschitz equivalent to the integer lattice. The argument is based on the
construction of a continuous function which is not the Jacobian of a
biLipschitz map.Comment: LaTeX2e file, 6 page
Semantic Compression for Edge-Assisted Systems
A novel semantic approach to data selection and compression is presented for
the dynamic adaptation of IoT data processing and transmission within "wireless
islands", where a set of sensing devices (sensors) are interconnected through
one-hop wireless links to a computational resource via a local access point.
The core of the proposed technique is a cooperative framework where local
classifiers at the mobile nodes are dynamically crafted and updated based on
the current state of the observed system, the global processing objective and
the characteristics of the sensors and data streams. The edge processor plays a
key role by establishing a link between content and operations within the
distributed system. The local classifiers are designed to filter the data
streams and provide only the needed information to the global classifier at the
edge processor, thus minimizing bandwidth usage. However, the better the
accuracy of these local classifiers, the larger the energy necessary to run
them at the individual sensors. A formulation of the optimization problem for
the dynamic construction of the classifiers under bandwidth and energy
constraints is proposed and demonstrated on a synthetic example.Comment: Presented at the Information Theory and Applications Workshop (ITA),
