Theil-Equilibrium based Cooperation Mechanism for multi-services in ubiquitous stub enironments

With the development of ubiquitous networks, the personalization of ubiquitous services demand different kinds of heterogeneous devices to cooperate with each other. However, limited network resources and device capabilities will cause allocation conflict of multi-services utilities for multi-users´ requests in ubiquitous stub environments. Thus, when users request simultaneously, how to make an effective device cooperation scheme to guarantee and equilibrate each user´s experience becomes a tough problem. In this paper, Equilibrium Index and Theil Utility function are firstly imported to establish the model of Multi-services Equilibrium Device Cooperation. Then a Theil-Equilibrium based Cooperation Mechanism for multi-services is proposed, including dimensionless processing and a cooperation approach focused on Theil-Utility Heuristic algorithm. At last, simulation results show this mechanism performs well in supporting ubiquitous services.
