In MANET, reliable and secure communication is the most challenging task. Mobile ad hoc network (MANET) is characterised by mobile hosts, dynamic topology, multi-hop wireless connectivity and infrastructure less ad hoc environment. Limited resource availability such as battery power and security are the major issues to be handled with mobile ad hoc networks. An attacker can easily disrupt the functioning of the network by attacking the underlying routing protocol. Hence, security in ad hoc networks is still a debatable area. In this paper, we have proposed energy-based efficient authenticated routing protocol (EBEARP) for mobile ad hoc networks. Our protocol provides efficient security against route discovery attacks using hop-by-hop signatures. It quickly detects the malicious nodes, thus assisting the nodes to drop the invalid packets, earlier. It also uses an efficient node selection mechanism, which maximises network life time and minimises power consumption. With the help of detailed simulation studies, we show that EBEARP provides better packet delivery ratio with minimised energy.
