SEMINAR ON FAST DETECTION OF MOBILE REPLICA NODE ATTACKS IN WIRELESS SENSOR NETWORKS

ABSTRACT

An adversary can capture and compromise sensor nodes, make replicas of them, and then mount a variety of attacks with these replicas.Several replica node detection schemes have been proposed. However, these schemes rely on fixed sensor locations and hence do not work in mobile sensor networks. In this project, a fast and effective mobile replica node detection scheme is proposed using the Sequential Probability Ratio Test.

INTRODUCTION

The attacker capture and compromise mobile nodes, and then use them to inject fake data, disrupt network operations, and eavesdrop on network communications.The replica node attack, in which the adversary takes the secret keying materials from a compromised node, generates a large number of attacker-controlled replicas that share the compromised node’s keying materials and ID.

MODULES

The following modules are present in the project
1.Mobile Node Network Creation
2.Mobile movement (Random walk) within given speed
3.Updation of location information
4.Updation of location information by Base station.
5.Replicate node
6.Detection of replica node using SPRT.

MODULE DESCRIPTION

1) MOBILE NODE NETWORK CREATION
Retrieve ‘n’ number of nodes ids’ from the database table and drawn in any x and y axis locations.
2)MOBILE MOVEMENT (RANDOM WALK) WITHIN GIVEN SPEED
All nodes are allowed to roam in any direction by incrementing x-axis or y-axis or both within the specified maximum limit.
3) UPDATION OF LOCATION INFORMATION
All nodes calculates the neighbor nodes with their transmission range .It gives location information . Occurs at regular intervals.
4) UPDATION OF LOCATION INFORMATION BY BASE STATION.
Base station collects location information from all nodes. occurs at regular intervals.
