The input parameters are very crucial in simulation tools for the analysis of data after the implementation. Authors in Mobile ad hoc Networks and particularly in Internet gateway discovery, face some challenges on how to decide on the choice of specific parameters. A wrong choice of input parameters could lead to a doubtful result by other researchers. A best practice is to follow what other authors are using as input parameters in their paper. This review analyses 72 proceeding papers and articles in different digital libraries: google scholar, IEEE Xplore, Elsevier, Springer, and snowball from 2010-2020. We present the result of our survey in this paper. We recommend the input parameters research should use base on the high utilisation as reference. Our review will help the community in MANET and Internet gateway to improve the credibility of the input parameters.

<p class="0abstract"><span lang="EN-US">Mobile ad hoc Networks researchers need to apply specific parameters in the simulation tools chosen to analyze and discuss their results. The challenge faced by multiple authors is on how to decide on the choice of particular parameters. A wrong choice could lead to a no credible result and a doubtful result by other researchers. A best practice is to follow what other authors are using as input parameters in their paper. This review analyses 72 proceeding papers and articles in different digital libraries: google scholar, IEEE Xplore, Elsevier, Springer, and snowball from 2010-2020.

A Mobile Ad-hoc Network (MANET) protocol performance analysis depends on the type of simulation tools, mobility models, and metrics used. These parameters' choice is crucial to researchers because it may produce an inaccurate result if it is not well chosen. The challenges researcher is facing are on the choice of these four parameters. Our survey shows an inclination to used Ad-hoc On-Demand Distance Vector routing (AODV) for performance comparison and enhancement of it by the researcher. Network simulation 2 (NS2) was the most selected tool, but we observe a decline in its utilization in recent years. Random Waypoint Mobility model (RWPM) was the most used mobility model. We have found a high percentage of the published article did not mention the mobility models use; this will make the result difficult for performance comparison with other works. Packet Delivery Ratio (PDR), End to End Delay (E2ED) were the most used metrics. Some authors have self-developed their simulation tools; the authors have also used new metrics and protocols to get a particular result based on their research objective. However, some criteria of choosing a protocol, metrics, mobility model, and simulation tool were not described, decreasing the credibility of their papers' results. Improvement needs to be done in the Ad-hoc network in terms of benchmark, acceptable scenario parameters. This survey will give the best practice to be used and some recommendations to the Ad-hoc network community.
