The problem of secure routing and data security in Internet of Things (IoT) networks is analyzed, and the nature of IoT nodes in terms of behavior introduces a higher threat towards data transmission and data security. The existence of malformed malicious devices introduces different threats which degrade the performance of entire IoT networks, and the services provided. To handle this, there are a number of secure routing algorithms prescribed in literature that have great deflection in the performance in secure routing and data security. To improve security, an Adaptive Service Dependent Secure Blockchain Model (ASSBM) is presented in this article. The model focused on two constraints: (1) maximizing the service throughput by incorporating a secure routing algorithm with Transmission Behavior Analysis, which analyzes the behavior of different IoT nodes in different data transmissions to measure the Transmission Leverage Trust (TLT) and used towards route selection, and (2) improving the data security by adapting service-centric blockchain algorithm which applies data encryption with different encryption schemes and keys being selected according to the nature of service. By classifying the services under different categories, the selection of encryption schemes and keys are differentiated between various classes of services. Both stages support the improvement of data security and secure transmission. The ASSBM model hikes the secure routing and data security performance.
