Energy efficient network method using delay tolerant network

Computer usage with network has been growing rapidly. The problem is that the energy usage of the networked computer sending data and one not sending data are similir. In this paper we build the method for network power saving by suing delay tolerant network. DTN method will be suitable for energy efficient network because every node in the network will store the data transmitted untill the destination is on. The method used in energy efficient network is to make every node is on and off based on the schedule. This on-off method will reduce the energy usage.
