In distributed systems a computer generally process information of distributed application or provide service in distributed system. Therefore, computers connected in distributed system need to keep on all time. It leads to the concept of Wake-on-LAN (Local Area Network). However, keeping on during the idle period is the wastage of power. Therefore, it is essential to save the power while being efficient in network management. In this paper we propose an improved Wake-on-LAN device that incorporates the usage of basic Wake-on-LAN technology into a network management and power saving product. © Springer India 2014.
