Key mechanisms for wireless sensor networks

Wireless sensor networks have been identified as being useful in a variety of domains to include military sensing and tracking, environment monitoring, patient monitoring and tracking smart environment, etc. When sensor networks are deployed in a hostile environment, 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 mechanisms, including those developed for Mobile Ad-Hoc Networks, are inadequate for wireless sensor networks. In this paper, we give some security mechanisms to adapt to wireless sensor networks for sensor data and network control protocols.
