Abstract

Due to the mobility of nodes, link failures, dynamic topology, as well as limited energy and bandwidth of the nodes, recovery strategies for service composition have caused a widespread concern in dynamic network. Different from rollback mechanism of post service composition interruption, Backup Service Replacement Strategy (BSRS) can accelerate the service repair process. In this paper, we propose two novel recovery strategies based on BSRS: Cold Backup Service Replacement Strategy (CBSRS) and Hot Backup Service Replacement Strategy (HBSRS). Experiments are conducted to show that the proposed strategies significantly improve the performance of service composition and effectively guarantee the availability and reliability of service composition in dynamic network.
