The wireless sensor network is one of the most significant technologies in the 21st century. So far wireless networking has been focused on high-speed and long range applications. However, there are many wireless monitoring and control applications for industrial and home environments which require longer battery life, lower data rates and less complexity than those existing standards. As an open and global standard for wireless sensor network, ZigBee shows advantages on low-cost, low power consumption and self forming. The ZigBee standard has been developed by the ZigBee Alliance based upon the IEEE 802.15.4 standard. The paper deals with the experimental results related to star topology implementation of wireless sensing network for process automation.Keywords

Iris recognition is accepted as one of the most efficient biometric method. Implementing this method to the practical system requires specific image processing where the iris feature extraction plays a crucial role. The first step in recognition is iris localization which consists in finding the iris boundaries as well as eyelids. In iris recognition system the maximum time is required for localization. In the recognition process the image acquisition system and size of theimage is an important for accuracy and overall system performance. Most of image processing algorithms are computationally intensive, so it is desirable to implement them in high performance reconfigurable systems. Recently, Field Programmable Gate Array (FPGA) technology is appropriate target for the implementation of algorithms for image processing. In this paper iris localization and iris recognition algorithms are implemented in MATLAB first, then the attempt has been made to design and develop iris recognition algorithm on FPGA. In addition, some of the optimizations are proposed and analyzed. Proposed solution is applied to 150×200 size colored images acquired under realistic conditions (UBIRIS Database).
