4.2.3. Experiment Three

Aim: The final set of experiments examined the connection between the likelihood of recovery and the handoff threshold. There is a favorable correlation between increasing the handoff rate and the likelihood of completing the recovery process. Handoff involves moving a MS from one base station to another. Algorithms with set parameters do not work well in varying system configurations. Handoff algorithms should take into consideration the communication system's peculiarities. If the preparation time of rapid handoff is longer than the WLAN sojourn time linked to mobile node speed, the handoff fails and packets are lost. If the mobile node speed is too slow, handoffs are initiated too late, reducing WLAN service duration. The handoff cost comprises the checkpoint status, message log, and acknowledgement.

Main Results: Figure 6 plots the completion of the recovery process against increases in the hand-off threshold rate. The recovery likelihood is significantly reduced when using the log managemen<sup>t</sup> technique, but the hand-off threshold rate is raised. Alternatively, some techniques decreased gradually when the threshold value was increased.

Discussion: The results demonstrated that the log technique is applicable only in small work settings. Whereas the hybrid approach and the agent-based method both performed well for areas with multiple regions or regions located farther from the site of retrieval. As anticipated, the suggested model has a higher recovery probability in the long term when compared to the other methods in the various simulated settings.
