This paper investigates throughput and delay based on a traffic pattern, called converge-cast, where each of the n nodes in the network acts as a destination with k randomly chosen sources corresponding to it. Adopting Multiple-Input-Multiple-Output (MIMO) technology, the authors devise two many-to-one cooperative schemes under converge-cast for both static and Mobile Ad hoc NETworks (MANETs), respectively. They call them Convergimo Schemes. In static networks, the Convergimo scheme highly utilizes hierarchical cooperation MIMO transmission. This feature overcomes the bottleneck which hinders converge-cast traffic from yielding ideal performance in traditional ad hoc network, by turning the originally interfering signals into interference-resistant ones.
