A Dynamic Route Construction Method Based on Measured Characteristics of Radio Propagation in Wireless Sensor Networks

In this paper, we propose a dynamic route construction method based on measured characteristics of radio propagation in a real environment. Our method first measures characteristics of radio propagation for each link, and determines a communication route from every node to the sink node and its transmission power based on the measured characteristics. While operating the system, our method dynamically reconstructs communication routes according to the change in the characteristics of radio propagation. We conduct an experiment to verify that our method can construct efficient communication routes in terms of energy-efficiency and quality of communication even when the characteristics of radio propagation dynamically change.
