Sliding mode controlled bifurcations for power control in wireless networks with mobile users
Mihaela R. Cistelecan · 2008
The paper presents a method for adjusting power in wireless networks consisting of mobile users. The proposed methodology takes advantage of the system nonlinearity by coherently changing the stability of the system equilibria. A decentralized sliding mode based controller was introduced, for each node of the network, to control bifurcations. The control law tries to always maximize the Signal-to-Interference-Ratio (SIR) of the node, despite the unknown perturbation coming from the interaction with the other nodes in the network.
