Man-In-Middle Attack/for a Free Scale Topology

In a Wireless Sensor Network (WSN) which is heavily deployed, shortest direct communication would be possible for a node to its numerous neighboring nodes. When the connection is established with moderate transmission power, the method is not beneficial. But at the same time lot of energy required for high power. Recent research has taken new tasks to further development of various net-work protocols like energy feeding, network exposure, fault in nodes, node failure tolerance, lifetime of network has to be conserved in WSN. Better topology has been employed in this paper that leads to better performance of WSN with man in middle attack. In this paper, a modified scale free topology had been proposed that leads to various advantages of tolerance against intrusion, fault and also some selective remove attacks.
