Título: "A sensor network for cold chain monitoring: experiments and simulations"

Monique Becker
Director of the CNRS lab: SAMOVAR at Telecom Sud Paris

The research work concerns the design of an end to end sensor network
controlling the temperature in the warehouses as well as in the trucks.
The sensor network in a truck has 33 sensors and each of them can communicate directly with each other.
A synchronisation algorithm "Placid" was designed for those sensors.
In a warehouse there is a very large number of sensors and multihop communications have to be used.
Several results were obtained for the cluster's building.
Some of them are theoretical, some were derived from simulations.
Measurements were run for a 50 sensor networks.
An on progress work concerns the automatic context switching from the "so-called truck network" to the "so-called warehouse network".
