Video applications in the Internet of Things benefit from multipath routing strategies to meet Quality of Service requirements. Although several multipath selection mechanisms have been proposed, changes in topology and/or in video services requirements can impact video quality. This work presents a wireless network architecture that enables dynamic routing, adapting these changes to new path solutions that provide a better Quality of Experience for the users. Simulation results demonstrated that the proposed architecture is capable of recovering video quality in case of degradation due to topology change, as well as also confirming that the presence of control flows, essential for maintaining the topology, reduces the final video quality.
