Abstract
WSN (Wireless Sensor Network) has a wide range of applications.WSN are mainly used in many real world applications for monitoring the approach. AOMDV is an On-demand multipath reactive routing protocol. This protocol initiates route inventory process between sender and receiver in multiple paths, and these paths are guaranteed to be loop free. In this paper investigates the problem of minimizing the packet loss rate in the presence of malicious sensor nodes in the network. The malicious sensor nodes are identified based on energy threshold in the network. The packets are transmitted from source to the destination in malicious free path by using Hashing Technique. The nodes which are having excess energy threshold levels these nodes considered as malicious sensor nodes. Usually malicious nodes are identified based on malicious message transmissions in a network. In this paper, it forwards the data from source to destination securely with the public key and private key in Hashing Technique. The simulation result shows that this approach achieves a very low packet loss rate and high throughput with variation in data rates in the presence of malicious sensor nodes in the network.
