Security Protocols in MANETs

Mobile ad-hoc network (MANET) is one of the recent active fields and has received marvelous attention. MANET is a collection of mobile nodes having the capability of forming temporarily network without the aid of any established infrastructure or centralized administration. Due to the self-configuration and self maintenance capabilities, MANETs become more vulnerable. So, Security challenges have become a primary concern to provide secure communication between mobile nodes. Many techniques have been developed to identify different type of network attacks. In this paper, we study the major attack types that MANET faces and the security goals to be achieved. This paper gives out a brief survey of major security protocols with their relative comparison.
