A Mobile Ad hoc NETwork (MANET) is a self-configuring infrastructure less network of mobile devices connected by wireless. Most of presented works on mutual communications are focused on link-level physical layer issues. The impacts of supportive communications on network-level upper layer issues, such as routing, topology control and network capacity etc. In this, the authors propose a Capacity-Optimized COoperative (COCO) topology control scheme to develop the network capacity in MANETs by mutually taking into account both upper layer network capacity and physical layer mutual communications. Though the physical layer cooperative communications have more important impacts on the network capacity and the future topology control scheme can significantly improve the network capacity in MANETs with cooperative communications and proposed optimum relay nodes selection for cooperative communication network to reduce overall power consumption of network.
