A comparison on a number of control packets generated.
|Protocol||Number of control packets generated||Reclustering/CH rotation frequency|
|First round||Rest of the rounds|
|LEACH||N + NCH||N + NCH||In every round, reclustering happens at local level.|
|LEACH-C||N + 1||N + 1||In every round, reclustering happens at the BS level.|
|BCDCP||N + 1||N + 1||In every round, reclustering happens at the BS level.|
|VCH-ECCR||N + NCH||N + NCH+ 1||Clustering occurs after every 1.85 rounds. See Figure 5 to see the average reclustering time for VCH-ECCR.|
