Changes in key performance indicators by phase transition in Internet of Things

Internet of Things (IoT) changes many industries in different service sectors as “digital service providers” in conjunction with information communication technologies. During this change, we are observing phase transitions in values of communication infrastructure. The initial values were information obtained by individual devices and communication itself amongst the devices. Being connected itself was valuable. We, however, observe phase transition in what is valuable. The more IoT environment evolves, the less we take care of individual devices and connectivity amongst them. Sets of information of a service in a higher layer form values for the entire system of the service. This shift in what is valuable then affects underlying network structures. We particularly focus on connected vehicles and discuss how the phase transition changes the key performance measure through our proposed use case of driving navigation service.
