Ant System Based Flexible and Cost Effective Routing for Wireless Face Recognition

Biometrics can be applied in existing systems for authentication with security, speed and ease of use. A wireless network is very suitable to incorporate biometrics into existing systems, and the integration requires reliable and efficient data routing within the system. Ant system is proposed to establish an adaptive route for data transmission among distributed nodes whilst maintaining the required bit error rate under varying channel conditions and consuming minimal energy. Face recognition is implemented in simulation to test the robustness and energy consumption of the biometric system within a wireless framework, and the results show that ant system based routing is efficient and as robust as a wired system, and there is no extra hardware needed to implement the routing.
