Abstract:
Wireless Sensor Networks are an emerging technology used for environmental monitoring. Security is a major concern when deploying a network for critical applications, such as military or medical surveillance. We have previously developed a security protocol that provides authentication, anti-replay, integrity and reliability. This paper presents further optimizations in order to minimize energy consumption. We have implemented the Energy-efficient Authentication and Anti-replay Security Protocol in TinyOS and we have tested its functionality and performance using the TOSSIM simulator. We have developed a mathematical model to evaluate energy consumption, determining the control overhead of the security protocol and the energy saved through the optimizations and thus proving the efficiency of the optimizations. The optimized EAASP represents a security protocol that provides strong authentication and anti-replay, integrity and reliability, and energy-efficiency.
