In this paper, we study path selection and power allocation problems for relay-aided systems with multiple source, relay, and destination nodes. To take fairness among different links into account, we aim at maximizing the minimum source-relay-destination link rate performance. We consider the scenario that the source node can be paired with any destination(More)
Let H denote the tree with six vertices two of which are adjacent and of degree three. Let G be a graph and u1, u2, a1, a2, a3, a4 be distinct vertices of G. We characterize those G that contain a topological H in which u1, u2 are of degree three and a1, a2, a3, a4 are of degree one, which include all 5-connected graphs. This work was motivated by the(More)
