Due to the rapidly increasing usage of personal mobile devices and the need of executing CVE applications in environments that have no previous network infrastructure, Mobile Collaborative Virtual Environments (MCVEs) systems will become ubiquitous in the future. In such systems, we enable users to act and interact in three dimensional world shared through their mobile devices in an ad-hoc network (MANET). A handful of interesting MCVE applications have been developed in a variety of domains, ranging from multiplayer games to virtual cities, virtual shopping malls, and various training simulations (i.e. military, emergency preparedness, Education, Medicine, etc.). The designers of such applications rely solely on network overhead, latency, limited bandwidth, and mobile device limitation. In this survey we present a number of ways to classify and analysis routing techniques that have been applied in Mobile Collaborative Environment Applications.
