Analysis and Elimination of Attackers in WSN using Secure Multipath Routing Protocol

Wireless Sensor networks are usually marshalled as group of nodes with a communication infrastructure leading to new structure of WSN called Cluster or Hierarchical WSN. In WSN, a primary requirement for the establishment of communication among nodes is that nodes should collaborate with each other. In the presence of malicious nodes, if the nodes interact or collaborate with each other, this will result in serious security issues; for example, such nodes may destroy the routing process. In this scenario, avoiding or diagnosing malevolent nodes launching DOS attacks through shortest path is a challenge. In existing system, to avoid and detect the malevolent cluster member and head, learning based energy prediction algorithm is used whose limitation is node failure, lack of direct communication, excess of energy consumption. This paper attempts to resolve this issue by designing a Secure Multi path Dynamic Routing Protocol based routing mechanism, which is referred to as the Attack Prevention Trust Scheme, that consolidates the advantages of both intense and sensitive defence architectures.
