Abstract: Due to WoT (Web of Things) is composed of numbers of resources-limited devices, it
is a challenging work that the optimal web service is selected from a similar functionality service
group based on the non-functional properties (QoS) without heavy interactive query process in
SOA (Service Oriented Architecture). This work focus on the dynamic update process of QoS
attributes vector and the optimal service selection algorithm based on the client's feedback in
WoT. The service time is estimated by the REM (Random Exponential Marking) which use the
concurrent clients number as the price index, and the exponentially weighted average of the
current service expense and the previous record. The service availability is estimated by the
online probability with the service state detection. The Empirical results based on NS-3.13
simulation show that the accuracy of optimal web service selection based on our presented
approaches is significantly better than the simple QoS attributes.
