Abstract: Churn handling has become an active area of research due to increased complexity, high dynamicity of participating nodes and its effect on the performance of overlay network. In this paper, we systematically analyse churn, its causes and implications along with churn handling strategies employed in various state of the art structured overlay network. These churn handling strategies are classified into two main categories based on addressing effects of churn: Churn Resilience and Dynamic repair strategies. These techniques are further classified into sub categories based on their inherent mechanism for addressing a particular concern. In addition, this paper pinpoints various concerns related to the future research for handling participant’s churn.
