Security and Quality of Service and Aspects in ZigBee-based Wireless Communication

Based on the IEEE 802.15.4 standard, which defines the physical layer (PHY) and medium access control (MAC) sublayer specifications for Low Rate Wireless Personal Area Networks (LR-WPAN), the ZigBee Alliance complements the specifications at the network, security, and application layers and provides an open global standard for building ultra-low complexity, ultra-low cost, ultra-low power consumption, and low data rate WPANs. ZigBee has become one of the most recent and promising WPAN technologies and is getting more popular in wireless sensor network (WSN) applications.
This project is a cooperated with SIEMENS AG A&D. Our primary research goals focus on quality of service (QoS) and security aspects in ZigBee-based WSN. We stress simulation and modeling techniques for performance evaluation. A complete model for the IEEE 802.15.4/Zigbee protocol stack is to be implemented in OMNeT++. This simulation tool has been extensively employed in our group. In our simulations, we apply various traffic models to investigate both, traditional performance measures (delay, latency, throughput, etc.) and other measures specifically for WSN like energy efficiency and real-time behavior (stressed in industrial monitoring and controlling). Self-organization has been identified as a promising control paradigm for massively distributed systems. We will also examine its applicability in ZigBee-based networks. With respect to security we are interested in the cost of the various available security mechanisms proposed in ZigBee specification. Simulation results will reveal how these security mechanisms affect the network performance. In the long-run, we aim to develop simulation-based methodologies for designing sensor networks for industrial control applications.
