Modulation and routing protocols for wireless control systems - D05.03, FeedNetBack

This document summarizes the progress made in four research lines related to modulation and routing protocols for wireless control systems with energy-limited resources. First, a report entitled "Timely, reliable and energy efficient routing over wireless sensor networks" proposes an energy-efficient protocol for control applications over WSNs based on the IEEE 802.15.4 standard. This protocol allows the network to adapt dynamically to requirements variations typical of controllers. The second section of this report, entitled "Energy efficient configuration of 802.11e networks subject to QoS requirements" deals with configuration of 802.11 MAC parameters with the aim of achieving maximal energy efficiency while minimum QoS requirements are satisfied. The third part, "Min-Max Model Predictive Power Control Strategy for CDMA Cellular Networks" deals with the uplink power control problem within CDMA cellular networks and proposes a model predictive control (MPC) strategy to compensate the channel fading uncertainties. The fourth part, entitled "Dwell-Time Adaptive Delta Modulation SignalCoding For Networked Controlled Systems" deals with the problem of control with limited data rates in the area of Networked Controlled Systems (NCS) and looks for a new adaptive quantization algorithm that reaches global stability for multivariable systems, while minimizing the required bandwidth, and has a smooth transient behavior.
