Prioritized soft constraint satisfaction: a qualitative method for dynamic transport selection in heterogeneous wireless environments

This paper presents prioritized soft constraint satisfaction (PSCS), a novel approach to selecting the \´\´best" transport in dynamic wireless transport switching systems. PSCS maintains a satisfying connection to another end point by choosing transports based on a user-established range of preferences and priority for criteria such as speed, power, range and cost. Additionally, feedback is provided regarding tradeoffs among the criteria, thus enabling the user to adjust inputs according to the capabilities of the system. We also recommend guidelines for setting preferences and priorities.
