Set of Power-Management Patterns for Mobile Embedded Systems

Embedded systems are part of our daily lives. One example is the emerging application of wireless payment using Near Field Communication (NFC). For example, in an NFC application, a terminal communicates with a wireless credit card for payment. Both terminal and credit card are embedded systems. Apart from other resource constraints, like limited computation power and memory, the available electrical power is limited on such systems as for instance the credit card. Power-management techniques have to be applied to deal with this constraint. In a previous work a pattern language and an example pattern called Energy Valve has been presented. Continuative, two additional patterns and one pattern idea for power-management in embedded systems are mined from existing techniques originally applied for NFC-Systems. These four patterns form a set of patterns for power-management in mobile embedded systems.
