Abstract

Wireless microsensor networks, which are used to monitor the physical environment, have become an important area of application for wireless technologies. The key attributes of these new types of network systems are strictly limited computing and energy resources, as well as a special working environment. This article examines aspects of the communication security of these networks. Resource constraints and the specific architecture of sensor networks require individual security mechanisms. Our approach is to classify the types of data that exist in sensor networks and identify potential threats to communication security according to this classification. We offer a communication security scheme, where for each data type we define the appropriate security mechanism. Using this multi-tiered security architecture, where each mechanism has different resource requirements, we provide efficient resource management, which is important for wireless sensor networks.

Key words: wireless sensor network, sensor, communication, protection.
