In such a case, the sensors are said to censor their observations by not sending observations that fall within a certain criterion.
Communication has been of great importance in cyber-physical systems (CPSs), which sends observations of the physical dynamics from the sensor to the controller as illustrated in Fig. 1.
The Secchi3000 water quality measurement system consists of the following parts: 1) mobile phone application for acquiring and sending observations, 2) Secchi3000 measurement device, 3) algorithms for analysing the water quality values from the images received, and 4) database, where all the data with analysed values are stored.
Ambassadors regularly send back observations of political events in their host countries, summarising developments and opinions.
Volunteers anywhere in the world can register online to view photos on their Web browsers, and send their observations to researchers at the planetarium.
Due to possible channel capacity, energy budget or topological constraints, it is assumed that at each time step only a subset of the available sensors can be selected to send their observations to the fusion center, where the state of the system is estimated by means of a Kalman filter.
The African Union, however, will send an observation mission headed by former Nigerian president Olusegun Obasanjo, who rubber-stamped president Robert Mugabe's disputed victory in Zimbabwe in 2013.
Pyongyang said the launch was intended to send an observation satellite into space but it drew international condemnation as the rocket technology is similar to that used for ballistic missiles.
Spectrum sensing data falsification attacks (SSDF) Attackers send false observation information, intentionally or unintentionally, to the fusion center (FC), and let the FC make the wrong decision.
