denial of sleep attack

Denial of Sleep Attacks are attacks on the power supply of mobile devices and sensor components as used in wireless sensor networks(WSN). The attacks on the sensors ' power supply aim to change their operating state and force them from Sleep Mode to Active Mode. This causes faster battery drain, reduces component lifetime, and leads to a higher risk of failure.

Wireless sensor networks for industrial or scientific use, for energy and home networks, consist of simple sensors. Only the simplicity of the sensor components allows them to be implemented at low cost, but without protection against attacks.

Denial-of-sleep attacks aim to discharge batteries faster, thereby limiting the functionality of the components. They switch the operating state, which in the case of sensors in particular goes into sleep mode after retrieving data, to the active transmitting state, causing batteries that should last for several years to run down in a few days.
