摘要：Wireless networks are becoming very prevalent now a day as the users need wireless connectivity regardless of their geographical location. Mobile adhoc network is decentralized, selfconfigurable and autonomous wireless network in which mobile nodes can join or leave the network any time. The term adhoc means no fixed infrastructure i.e. Dynamic Topology. Apart from these features, MANET suffers from many security issues viz. external and internal attacks. Providing a secure communication between source and destination is one of the major problem in Manet. This paper describes a novel technique for establishing a secure path from source to destination by using Diffie Hellman algorithm. This is done after isolation of black hole attack. Simulation results are shown for packet delay and packet loss for different number of nodes. The technique provides improvement over the previously defined methods in terms of delay and packet loss. The simulation is done on Network Simulator2.
