Enhancement of security by using greedy approach and encryption inMobile Ad Hoc Network

Mobile Ad hoc Network (MANET) is a position of mobile phone devices like which correspond surrounded by each other in excess of wireless relations lacking a preconceived communications or a essential weight. The associate nodes are self dependent pro design, function also continuation of the association by means of only hop or multi hop communication. In existing work, RSA and Triple DES algorithm are used to detect malicious nodes but we performed greedy approaches and encryption which provides much better results. This shows in the NS2 Simulation which proved that our methodology is far better than the existing work.
