Trust-aware Framework for Application Placement in Fog Computing

Internet of Things (IoT) devices are unable to handle enormous data generated by IoT applications due to limited computing capability. So IoT applications are placed at Cloud for computation, but it also faces latency and bandwidth issues. Fog computing addresses these issues of cloud by providing computation near to IoT users. In selection of fog nodes for application placement problem, trust plays a vital role. In our proposed model, we use trust as dominating factor for selection of fog nodes. The proposed model removes/curtails the malicious fog nodes during placement of applications. A case study is given for showing how trust can give benefits to IoT users.
