I overcame TDMA problems associated with mesh broadcast networks by moving channel allocation logic into the application layer. For me it was more important for reliable delivery then bandwidth. We use geo spatial TDMA to further allocate the channel, two proximity peers would have vastly different time slots. Unfortunately this leaks location data (though most 2GHz channels will). Besides wifi + bluetooth channels, we have leveraged acoustic channels (more so for unidirectional communication from a watch tower to all peers within an ultrasonic range)
