Fairness for Dynamic Control [chapter]

Jochen Hoenicke, Ernst-Rüdiger Olderog, Andreas Podelski
2010 Lecture Notes in Computer Science  
We believe that our results shed new light on the concept of fairness in the setting of dynamic control.  ...  In this paper, we present the extension of a fair scheduler from 'static control' (the number of processes is fixed) to 'dynamic control' (the number of processes changes during execution).  ...  We thank Andrey Rybalchenko for helpful comments on this paper.  ...

Power control for fair dynamic channel reservation in VANETs

Parisa Haghani, Yih-Chun Hu
2012 2012 9th Annual IEEE Communications Society Conference on Sensor, Mesh and Ad Hoc Communications and Networks (SECON)  
In this paper we compare the performance of IEEE 802.11p and a recent time-division based medium access control protocol, Dynamic Channel Reservation (DCR) in realistic high-density traffic scenarios.  ...  These applications require fair (i.e., all vehicles get equal fraction of time allocation for their transmissions) and reliable (i.e., transmissions are received with high probably by the intended receivers  ...  The problem of ensuring fairness is defined as a minmax optimization problem and a centralized algorithm, called FPAV (Fair Power Adjustment for Vehicular Environments), is presented for achieving this  ...

Consensus-Based Torque Control of Deloaded Wind DFIGs for Distributed and Fair Dynamic Dispatching [article]

Stefanos Baros
2016 arXiv   pre-print
In this paper we aim to address the problem of dynamically dispatching a group of state-of-the-art deloaded wind generators (WGs) in a fair-sharing manner.  ...  Finally, we derive a cooperative Control Lyapunov Function-based (CLF) controller for the rotor side converter (RSC) of each WG that realizes the protocol in practice.  ...  The control logic for each RSC follows equation (32) (Fig. 1) whereas the group objective for the RSC controllers is to dynamically self-dispatch their WGs in a fair-sharing way and the WF power output  ...

On Dynamic Control Parameter Configuration Mechanism for Inter-and Intra-VPN Fairness Control Mechanism

O. Honda, H. Ohsaki, M. Imase, J. Murayama, K. Matsuda
2005 6th Asia-Pacific Symposium on Information and Telecommunication Technologies  
In this paper, we first discuss design goals of a dynamic control parameter configuration mechanism for I2VFC.  ...  In order for I2VFC to achieve fairness among IP-VPN customers in arbitrary network configurations, I2VFC control parameters need to be automatically configured.  ...  That is, I2VFC itself does not perform any control for achieving intra-VPN fairness.  ...

Approximate stochastic dynamic programming for opportunistic fair scheduling in wireless networks

Zhi Zhang, Sudhir Moola, Edwin K. P. Chong
2008 2008 47th IEEE Conference on Decision and Control  
We derive and prove an explicit dynamic programming equation for the above constrained MDP, and give an optimal scheduling policy based on that equation.  ...  Taking fairness constraints and the memory property of channels into consideration, we formulate the transmission scheduling problem as a discounted reward Markov decision process (MDP) with temporal fairness  ...  We derive and prove an explicit dynamic programming equation for MDPs with temporal fairness constraints.  ...
