On Communication Security in Wireless Ad-Hoc Sensor Networks

s of wireless microsensors for monitoring vironments have emerged as an important new area for the wireless technology. Key f these new types of networked systems are the nstrained computational and energy resources, hoc operational environment. This paper is a he communication security aspects of these Resource limitations and specific architecture networks call for customized security s. Our approach is to classify the types of data n sensor networks, and identify possible tion security threats according to this on. We propose a communication security where for each type of data we define a ing security mechanism. By employing this security architecture where each mechanism nt resource requirements we allow for efficient anagement that is essential for wireless sensor ds—wireless, sensor, networks communication
