Wireless Sensor Network Security in Military Application using Unmanned Vehicle

Wireless Sensor Network is widely used in Military Applications like Tracking the enemy movements and force protection. Security is the major concern and very difficult to achieve due to the unattended nature, limited memory, and limited power of network. This paper is mainly intended to describe the implementation of the secure unmanned Vehicle Navigation system controlled by wireless sensor network. We used a cluster based approach to prevent the various types of attacks in military field. We propose armed and sealed mote to prevent the physical attacks. In order to avoid a single key compromise lead to the entire network compromise we have proposed a modified version of LEAP for key management. The vehicle navigation was implemented using a toy car controlled by a micaz mote inside it. The GPS unit is connected with the vehicle to determine the position and in the absence of GPS range we can use the relative position. The vehicle can directly send the messages to the nearest sink node. The vehicle is used for making the application more secure and all the costly devices needed for the application can be incorporated with the vehicle. This paper shows how we can use the unmanned vehicle navigation system in Military applications and how it is used to detect the intruders and prevents various kinds of security attacks in the military field.
