In wireless networks so far, multiple active flows and cooperative transmissions has not been yet considered. The case of VMISO links is considered here. To achieve this and to improve performance, cooperative transmission is used in multi-hop wireless networks. In the end, VMISO in physical layer benefits and improves network layer performance. After an investigation on this end result, we show that the improvements are non- trivial. A study is made on routing decisions and finally a Cluster Adaptive (ClAd) routing protocol is introduced. This protocol also strengthens Virtual Multiple Input Single Output (VMISO) links to achieve performance improvements. It also gives solutions to decision problems like the number of cooperating transmitters for each link and cooperation strategy used by the transmitters.
