Nowadays the Internet of Things (IoT) still does not have global policies and standards to deal with the interaction and the development of applications. There are huge of security issues relevant to the application layer of IoT becoming very urgent. On the other hand, it is important for addressing the development of security algorithm to protect the IoT system from malicious attack. In this article, a fusion diversity scheme adopts maximum ratio combining (MRC) and selection combining (SC) schemes with trust management (TM) security algorithm are proposed. In MRC stage, specified parameters first extracted and they weighted by one estimation value before combined with the control information. The fused information generated from MRC passed forward to the SC in order to calculate the final trust value. What degree of the quality of service (QoS) will provide with IoT technologies is dependent on the trust value comes from the previously step. The simulation results from experiments deployed with physical assessment show that the security has more reliability after the MRC and SC schemes fused into the TM procedure. That is, the proposed fusion diversity scheme is more reliable in terms of security. Furthermore, the mechanism fusing MRC and SC methods with the TM can enhance the efficiency and solve the security problem of application layer. Alternatively, the reducing in QoS degree, such as the data rate, the packet capacity for the requester is the penalty.
