A Novel Multi-x Cooperative Decision-making Mechanism for Cognitive Internet of Things

Cognitive Internet of Things (CIoT) mainly consists of a group of autonomous nodes (ANs) which are commonly combined into domains and should have the intelligence to perceive, analyze, decide and act. Cooperation has shown to be a good technique for collective behavior of ANs that locally interact with each other in distributed environments. In this paper, we study the cooperative decision-making mechanism of multi-ANs and multi-domains and present the corresponding cooperative decision-making process in CIoT. Multi-ANs cooperation deals with the cases that one AN cannot meet the QoS and network performance object (NPO) and multi-domains cooperation addresses the cases that the ANs of only one domain cannot meet the QoS and NPO. Based on the cooperative decision-making mechanism, the simulative experiments are done and show that the NPO can be satisfied perfectly.
