Service Negotiation in a Dynamic IoT Environment

In the Internet of Things (IoT), billions of physical devices connecting over the Internet provide a near real-time state of the world in a service-oriented way. The demand-driven service-provision paradigm may need a negotiation process to tailor the service properties before creating the service level agreement (SLA). Existing negotiation techniques are focused on the cloud computing, however, SLA negotiation is rarely discussed in the IoT environment. Thus, we extended a commonly-used web service negotiation framework based on characteristics of the IoT, integrated with a game theory-based negotiation strategy, and evaluated its performance under a simulation platform. Based on the result, we identified the research questions and outlined future directions.
