Decision Making over Communication Networks
Mobile computing and wireless communications for vehicle information technology is a clearly emerging trend. A salient feature of these systems is the coupling of dynamic components, sensors, actuators and embedded control systems via the underlying communication network. Networked control systems are common in cars, aircrafts, chemical/nuclear plants and thus questions regarding their stability are of great practical importance. Vehicular communication networks are usually ad-hoc and highly dynamic, with potentially large number of interacting nodes . Fax and Murrayuse tools from algebraic graph theory to model the communication network of intercommunicating vehicles and to study formation stability. Liu et al. examine the robustness of existing vehicle platoon control laws with respect to communication delays. The behavior of such systems can be highly sensitive to latency of message propagation, and therefore it is necessary to design networks and protocols to minimize the influence of communication delays. In addition, analytical and numerical bounds on the performance of the protocols should be derived.
