The integration of a Wireless Sensor Network which consists of a large number of low-cost, low-power, multifunctional and resource-constrained sensor nodes with cloud computing which is featured by powerful data storage and data processing capabilities, has become an important area of research in today’s technology driven world. The efficient utilization of cloud computing and wireless sensor networks integrated system demands transparency into the trustworthiness of the service provider. Existing works, compute trust and reputation of a service provider for every service it offers for each service user.
