This paper presents a novel coopetition paradigm based on bargaining theory for collaborative multimedia resource management. The paradigm consists of a judicious mixture of competition and cooperation. For competition, the well-known Kalai-Smorodinsky Bargaining Solution (KSBS) is adopted as the fairness criteria, and for cooperation each user stops competing for resources as long as it achieves a predefined threshold of Quality o Service (QoS). We apply the propose paradigm to rate allocation amongst multiple video users and compare its performance to other two schemes, traditional KSBS, and generalized KSBS for similar video quality. Results indicate that our paradigm adapts the best to the variation of resources as well as the user number. Also, importantly, our paradigm can result in an improved number of satisfied users while simultaneously avoid penalizing same users in the case of scarce resources. Complexity of the proposed paradigm is also analyzed.
