selection of cluster head in wireless sensor networks

I have deployed 100 nodes in a network...now I have to randomly select 10 nodes as cluster heads(using Euclidean distance)..... ch1: random selection among 100 nodes...... ch2: calculate Euclidean distance from ch1 to all other nodes.among them pick the maximum value and choose that node as ch2.... ch3: take the next maximum value and calculate distance from ch3 to ch2 and also from ch3 to ch1.then check for the following condition if(dist>200)elect that node as ch3 else take the next maximum value and repeat the process.........the above process should be repeated for the selection of 10 cluster heads....can anyone help me in creating the LOOP..
