Fault Tolerant Airborne Sensor Networks for Air Operations
Abstract
This report summarizes the main results of research conducted during the summer of 2007 on tasking a finite number of cooperative agents to randomly emerging targets for their removal. Faults occur when some agents engaged in a mission are expired. Agents are subject to threat at a level determined by the number of targets present. On the other hand, the rate at which a target is removed depends on the number of cooperative agents assigned to it. Faults effectively change the network architecture and, therefore, degrade the network performance. Designs of control policies that determine the number of agents assigned are based on the network life when expired agents cannot be replenished, and on the network availability when expired agents are replenished at a certain rate. Tasking process is described by a discrete event system in the form of a quelling network, where agents are servers and targets are customers. Optimal policies are determined by solving a Markov decision problem.
