ENERGY EFFICIENT AND SECURE ROUTING IN MOBILE AD-HOC NETWORKS- A SURVEY

An ad-hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any preexisting network infrastructure or centralized administration. However, due to the absence of central infrastructure the devices in the ad-hoc network can move randomly gives rise to various kind of problems, such as routing and security. The nodes in ad-hoc networks are typically battery powered. The need for energy efficiency in MANETs requires power enhancement features. The mobile ad-hoc networks also suffer from security attacks and privacy issues which dramatically impede their applications. To cope with the attacks, a large variety of intrusion detection techniques have been developed. Recent advances in MANETs have lead to many protocols specifically designed where energy awareness and security is an essential consideration. This paper surveys various approaches pursued for security and energy efficiency for different routing protocols and most of the time AODV provided better results. The proposed methods can also be implemented on DSR routing protocol to provide source routing and it can give better results than AODV routing protocol.
