Configuration Dissemination with State Feedback for Wireless Sensor Networking Systems

摘要

A wireless sensor network (WSN) is a group of spatially dispersed sensors for monitoring the physical conditions of the environment and organizing the collected data at a central location. Since WSNs typically have no infrastructure, one of the challenges in WSNs is the lack of an appropriate method for an operator to interact with a WSN. Practical tasks for WSNs require sensor nodes adaptive to changes in WSN configuration, user input, and commands; hence, monitoring and interaction with a WSN are required. In this paper, a new scheme for configuration dissemination with the monitoring of the sensor state is proposed to control dynamically the operation of sensor nodes in real time. Moreover, a method is provided for the operator to observe the state of a sensor node, which helps the operator provide an appropriate control input to the WSN. We prove the stability properties of the proposed algorithm and show the simulation results.
