This paper considers the joint power-allocation and relay-selection problems in multiuser cooperative communication networks, where one user can only seek a limited number of relays for cooperation. This relay-selection degree bound is of practical significance. The goal is to optimize the relay selection and power allocation in a distributed manner while respecting certain users' quality-of-service...
Adaptive cooperation with conflict-free relay assignment in a network setting is a challenging problem. The problem becomes even more difficult when users have quality-of-service (QoS) requirements but the available spectrum resource is limited, where admission control may be required. In this paper, we jointly study relay assignment and admission control in cooperative radio networks (CRNs). A one-stage...
