A performance detection method in embedded systems

Resorting to the concept of survivability from information systems, a survivable embedded system model was firstly designed. Then, we introduced a method of detecting the changes of performances in the system to decide when to active a certain sur-vivable strategy. This method can provide a good trade-off between survivability and other side effects. Additional, the algorithm’s sensitivity of the changes in performances can be adjusted via modifying several different parameters, so that it can be used in various situations properly.
