Enhancing security in Mobile Adhoc Network is a challenging issue. Mobile adhoc networks (MANET) designed to operate in more impetuous and swiftly changing environment. Enhancing MANET security is entirely different from the conventional methods of establishing security. There are many approaches in enhancing security in MANET. This paper discuss some techniques for belief evaluation of mobile nodes in MANET. In addition, this paper discusses about leader election scheme for mobile nodes.
