摘要：

In this paper we propose an integration of dynamic channel allocation capabilities, typical of cognitive radio networks, in wireless sensor networks based on IPv6 protocol. We analyze the fundamental aspects of the proposed frequency-agile wireless sensor networks, including spectrum sensing, channel selection, network architecture, extensions of the IPv6 stack, and system operation. We then present a complete implementation of a prototype which illustrates feasibility and effectiveness of the proposed solutions. Results show that dynamic frequency allocation provides significant improvement of performance and reliability in wireless sensor networks operating in highly interfered environments.
