Replica Node Attacks Detection in Mobile Sensor Networks Using Efficient and Distributed Scheme

The most wireless sensor networks are composed of unshielded sensor nodes. An adversary can easily attack, analyze and clone the unshielded sensor nodes and create replicas and insert them in the networks. This gives the adversary to carry on large class of insidious attacks like disrupting communication, subverting data aggregation, eavesdropping etc… in this research we resist against node replication attacks in mobile sensor networks. In this paper, we propose a new protocol to detect the replicas in mobile WSNs. in this protocol, efficient and distributed scheme and sequential probability ratio test are used to security that the replica nodes enters in to the monitoring area containing number of nodes under consideration the path travelled by the replica nodes are monitored and other nodes present I the area are prevented from attack using the efficient and distributed scheme.
