How a cyber-physical system can efficiently obtain a snapshot of physical information even in the presence of sensor faults
Björn A. Andersson, Nuno Pereira, Eduardo Tovar · 2008
We present a distributed algorithm for cyber-physical systems to obtain a snapshot of sensor data. The snapshot is an approximate representation of sensor data; it is an interpolation as a function of space coordinates. The new algorithm exploits a prioritized medium access control (MAC) protocol to efficiently transmit information of the sensor data. It scales to a very large number of sensors and it is able to operate in the presence of sensor faults.
