Autonomous and Dependable Recovery Scheme in UPnP Network Settings

Resources or devices on the network might be unavailable due to serious network partitioning. To provide a robust network connectivity, this paper presents an autonomous and dependable recovery scheme using teamwork in UPnP network settings. For our scheme, we introduce a team of recoverable control points and corresponding recovery device, and, in case of network failures among devices, the recoverable control points autonomously take care of the devices to achieve their mutual goal as a team member. In the experiments, we tested our recovery scheme in terms of the recovery effectiveness. It turned out that the recoverable control point agent in our scheme successfully handled the events from the devices, regardless of one of recoverable control points being killed. We argue that our recovery scheme is fairly consistent, and the control point agents can recover from failures as quickly as possible.
