feasible: all to one (UDP unicast or multicast) stream traffic, images from all mobiles/nodes sent to one mobile/node. TCP modified for node-to-neighbour operation or end-to-end. Can rely on synched mobiles (each using GPS signals for example). Out of band channel possible but substracted from the radio resources for user data (e.g., if OLSR is used, the TC and Hello msg can use the out-of-band channel, ... or not). With/out (perfect) rate adaptation. [Rayleigh] fading environment and SISO but MIMO like channels possible.

The general concept of using TDMA in WiFi like systems is prevalent. This is known as PTMP - Point to Multipoint system. It does use a master controller generally terms Base Station Controller. The BS initiates the conversation and other units respond.
In the case of MANET since each node is also capable of being a relay and a router, it is important to rearrange. If one unit is declared BS and allowed to assign channels then TDMA becomes straight forward. The reason is TDMA requires time sync, which is provided by the BS. In the enclosed (chapter 12) observe Fig 12.6.1 where the BS for each area initiates and controls on a given channel. In MANET channels for police from a Precinct (for example) or fire personnel from the area (for example) can all have pre-designated channels assigned. Then TDMA becomes straight forward. In all cellular systems (including GSM) this method has been followed. In PTMP (made by quite a few vendors) similar method is followed.
Hope this helps
