To conclude this study, we perform simulation studies to analyze and compare the performance of the final iRoutCluster design with existing protocols. The simulation results demonstrate that iRoutCluster outperforms its competitors in all assumed scenarios and metrics. We then implement the iRoutCluster protocol in MATLAB® simulator to further investigate its performance in mobile networks and large-scale static sensor networks. The results clearly show that iRoutCluster not only performs well in large-scale networks, but is equally good in MANETs as well. Therefore, iRoutCluster is a viable protocol for hybrid ad hoc networks.
