From the IoT perspective, each intelligent device can be considered as a potential source of service. Since several services perform the same function, albeit with different quality of service (QoS) parameters, service composition becomes a crucial problem to find an optimal set of services to automate a typical business process. The majority of prior research has investigated the service composition problem with the assumption that advertised QoS values are deterministic and do not change over time. However, factors like sensors failure and network topology changes cause uncertainty in the advertised QoS values. To address this challenge, we propose a novel Anomaly-aware Robust service Comp..
