Algorithm 2. Pseudocode for determining a coordinator.

while (the final winning master is not determined and T2 < T)   If p > 0.5 in each master,     the master is assigned to the scan mode   else     the master is assigned to the advertise mode   end if   if any two masters exchange information with each other     Compare their neighbor list     if the number of neighbors is equal       The winner is the node with the smaller Bluetooth ID, and becomes as a master     else the node with the most neighbors becomes the winning master       The losing node becomes as slave, and will deliver its neighbor list to the winner.       The losing nodes are removed until the final winning master is determined.     end if   end if end while
