Integrated Operational Control and Dynamic Task Allocation of Unattended Distributed Sensor Systems

摘要

Unattended autonomous systems of the future will involve groups of static and mobile sensors functioning in coordination to achieve overall task objectives. Such systems can be viewed as wirelessly networked unmanned heterogeneous sensor networks. We discuss a distributed heterogeneous sensing system with static sensors and mobile robots with novel control optimization algorithms for dynamic adaptation, coordinated control and end to end resource management of all sensors in response to detected events to achieve overall system goals and objectives. Our system is designed for a host of applications, such as unmediated data monitoring and record keeping of the environment, battlefield monitoring using integrated ground, ocean and air sensors, and reactive operation to threats or changing conditions, and homeland security or border/road surveillance systems where unmanned vehicles can be deployed autonomously in response to detected events. Results for large area coastal monitoring are presented. Offline results using actual modeled data from in-situ sensory measurements demonstrate how the sensor parameters can be adapted to maximize observability of a freshwater plume while ensuring that individual system components operate within their physical limitations.
