Novel approach to save energy through OSPF routing protocol

Now a days as compare to power resources power demand grows and energy cost is also increasing at constant rate. To reduce power consumption in entire network infrastructure lots of research developed. In this approach the solution to save energy is explain. In this approach Energy Saving IP Routing strategy is define. ESIR strategy work with Open Shortest Path First protocol. This strategy is useful for Internet Service Provider (ISP) backbone network. This strategy finds the shortest path between neighboring routers by using SPT exportation mechanism. Another mechanism defines in this approach which is known as Maximum Set of Compatible Moves. This approach saves the energy by using all this above mechanism and also with the help of putting the node in sleep mode instead of completely removing such node. This strategy provides energy solution with quality of services (QoS). The proposed system implement algorithm to switch off the link according to traffic variation.
