Thanks bob. But i have an extension to my second question. What if two ad hoc groups (A,B,C) and (D,E,F) using the same frequency channel and same SSID, come close to each other? Will they end up forming a single group? or will the BSSID's of the nodes be used to differentiate which nodes are in your group? Is there any work anyone knows that has characterized the overlapping of ad-hoc groups?
