Applied Self-Healing: Self-Aware Service Request Optimization for Gateway Stability in Ubiquitous Zone-Based Networks

In this paper, we present an application of self-healing systems in the form of service request optimization algorithm for service gateways. This algorithm preestimates the load of the gateway and accepts the service request according to the capability of the worker thread. The experimental and simulation results show that the performance of load control algorithm works well for managing the service request. Our study has revealed that normally the networks fail to entertain the requests after the saturation point. Whereas the algorithm proposed in this paper, virtually accepts the service requests almost always which is what is essentially required from hybrid network in a ubiquitous environment. The algorithm proposed is already embedded and are in work in the IT infrastructure of major banks of Korea.
