In order to increase channel capacity and energy efficiency in wireless ad hoc network, a novel Cooperative MIMO (CMIMO) transmission strategy is proposed in this paper. A weighted cooperative node selection algorithm which synthesizes bi-directional asymmetrical channel feature, nodes' residual energy as well as node connectivity is given firstly. Then a set of optimal nodes is selected by the strategy to constitute the CMIMO system. A mechanism to establish and maintain virtual link between two virtual nodes is researched while the CMIMO relay strategy with cyclic redundancy coding is used to improve system reliability and save resources at the same time.
