Intrusion Detection at International Borders and Large Military Barracks with Multi-sink Wireless Sensor Networks: An Energy Efficient Solution

Wireless Sensor Networks have profound applications in military systems. Intrusion at unmanned borders and at other sensitive places may be tracked using sensor networks. However, the domain of military applications could imply hostile environment and thus monitoring of the nodes of the deployed WSN could be practically impossible. It is thus required that the deployed WSN ensures low energy consumption to give a high network life such that the cost of deployment may be suitably amortized. In this paper we propose an energy efficient solution for detecting intrusions through unmanned borders and other sensitive places with prolonged network lifetime using two routing schemes: KPS and Loop Free (LF)-KPS. We have compared these two schemes with LEACH and TEEN, and have shown how data transfer through KPS and LF-KPS protocols would ensure an enhanced lifetime for the deployed network. At the end we have also shown the effect of looping on the lifetime of the deployed network.
