Power Optimized Secure Routing Protocol in Manet

Abstract: Power aware is important challenge issue to improve the communication energy efficiency at individual nodes in MANET. We propose here a POS routing protocol for MANET.POS identifies the capacity of the node not only battery power but also the energy spent in reliably forwarding data packet over a specific link .using encryption and decryption process POS creates a key between energy node to secure the message forwarded while creating these two path two parameters are also considered here of energy balance control and security parameter to send message using less energy and full security .these scheme reduces the power consumption , increases the network lifetime and increases the message delivery ratio
