Towards Planning Policies for Self-Adaptive Orchestrated Web Services

This paper aims to provide planning policies enabling self-adaptation of composed Web services in case of failure or Quality of Service (QoS) degradation. Therefore, we employ orchestration process mobility using different techniques. And, we propose a set of rules enabling the selection, at runtime, of the mobility techniques according to current execution conditions. These rules are validated through the evaluation of each mobility technique under different execution conditions in order to deduce which technique is more suitable in each condition.
