Re: the answer
So we need wireless token ring?
Err no, you need IEEE 802.4 Token Bus ie. logical ring over a shared-media.
But then that was really intended to be used in 'stable' networks and not dynamic networks such as WiFi hotspots, because establishing and maintaining the logical ring does carry an overhead; plus it requires all nodes to be active in the token passing, so the radio is always active, whereas in 802.11 the node only needs to power it's tx when it wants to send something.
Also designing these networks wasn't for the faint-hearted; says he who built several large 802.4 networks back in the 80's...
