All the nodes remain alive for VCH-ECCR till 27 rounds while it is 14, 16, and 21 for LEACH, LEACH-C, and BCDCP, respectively.
On average, the energy expenditure of VCH-ECCR is reduced by 50, 20, and 11 percent over LEACH, LEACH-C, and BCDCP, respectively.
The VCH-ECCR delivers 153819 data packets to the BS until the last node dies while LEACH, LEACH-C, and BCDCP deliver 102919, 121863, and 139500, respectively.
The average reclustering time for VCH-ECCR is 1.85 communication rounds approximately whereas for LEACH, LEACH-C, and BCDCP it is one communication round because, after every round LEACH, LEACH-C, and BCDCP perform re-clustering.
The number of control packets generated in VCH-ECCR is compared with the control packets generated in LEACH, LEACH-C, and BCDCP. Table 3 shows the number of control packets generated for LEACH, LEACH-C, BCDCP, and VCH-ECCR.
In BCDCP, all nodes send their current energy to the BS in every communication round.
In VCH-ECCR, the number of control messages generated in the first round is given by N + 1 similar to LEACH-C and BCDCP. On each reclustering, when any cluster goes into V-VCH status, new clusters are formed.
BCDCP utilizes a high-energy base station to set up clusters and uses MST [34] to connect cluster heads and randomly chooses a leader to send data to the base station.
