Security methods for wireless sensor networks

Wireless sensor networks can be used for a wide rang of potential applications such as military target tracking, environment monitoring, patient monitoring and scientific exploration in dangerous environments. When sensor networks are deployed in a hostile terrain, security becomes extremely important, as they are prone to different types of malicious attacks. Due to the resource limitations of sensor nodes, existing network security methods, including those developed for Mobile Ad-Hoc Networks, are not well suitable for wireless sensor networks. In this paper, we give some security methods to adapt to wireless sensor networks for sensor data and network control protocols.
