In the case of Internet-of-Things, the issues associated with real- world implementation are exponentially multi-fold. Although various simulators have facilitated the evolution of schemes to address the problems in IoT applications in the last few years, their applicability in the real world is highly questionable. Hence, this paper discusses the potential features of existing simulations (both commercial and research-based) and investigates features of different assessment environment tools to understand their current state. The paper further contributes toward a distinct research pattern. The core contribution of this manuscript is to review standard practices of using simulation tool along with different test environments. The paper also contributes towards exploring various prospects of unaddressed problems associated with a usage of existing simulation environment/tool for investigating the challenging and practical environment of an IoT ecosystem. The learning outcome of this study will assist the reader to make a decision towards adopting precise simulation tool for their work as well as it also highlights the need to perform more number of customization towards including the features that is found in research gap.

INTRODUCTION The process and various operation ranges involved in the real world are sometimes quite challenging to investigate and study, considering real-world entities. This problem can be solved by using simulation modeling to efficiently and safely perform the processes to offer solutions [1]. The implemented methods using different spectrums of the algorithm during the simulation study facilitate a simplified verification process over-controlled research environment [2]. This paper discusses the simulation perspective of studying various problems in Internet-of-Things (IoT), a network of different physical devices called things with distinct identifiers [3]. The dependable attributes for framing an IoT ecosystem are communication devices, sensors, processors, etc. [4]. An edge device or an IoT gateway node collects the sensory data shared via IoT devices and is forwarded to the cloud for storage or analysis [5]. However, implementing such a large ecosystem of an IoT is comprehensively a massive task as they are also associated with various implementation impediments, e.g., challenges of inappropriately aggregated data, processing of unstructured data, ensuring coverage and connectivity of a large number of IoT device, ensuring power management for resource constraint sensors, challenges associated with data storage, integrating with all points of an IoT with appropriate software, proper identification of an IoT device with legitimate authentication, and compatibility issues of a large number of heterogeneous system in an IoT [6]. However, it should be noted that IoT is not only about sensory data collection [7], routing [8], and storage [9], but it is strongly related to potential data analytical operations, too [10]. At present, there are various schemes to ensure an effective operation of IoT communication in the majority of the perspective [11]-[14]; however, it is seen that the majority of such studies are carried out using a simulation-based approach while only a few proportions of work is carried out over real-time models and data. Both such schemes (real world and simulation-based) have their benefits and limitation. However, simulation-based studies are still more favorable toward cost-effective analysis, leading to much successful deployment in the real world. However, such a simulation-based approach should be deeply investigated to find out if they are really at par with solving impending problems in an IoT. There is no doubt about the availability of a list of different simulators in current times for deploying novel logic for implementing an IoT. However, questions still arise about the taxonomies of such simulators, the discrete beneficial features towards cost-effective deployment, judging the applicability of simulation outcomes in the practical world, and finding the most adopted simulation tool in recent years. Finding answers to these questions will eventually guide better decision- making, either towards adoption or the evolution of new simulators in IoT. The prime motivation of the proposed study is to showcase the discussion on simulators with a higher and lower adoption rate in the last few years. Therefore, the novelty of the proposed study is towards assessing the functionalities and features of existing simulators towards investigating problems in IoT. Finally, the study also elaborates on the first and second levels of the research gap, unlike any existing research update. The contribution of the paper is as follows: 1) The paper offers a brief and compact insight towards the existing 5 standard simulation tools of an IoT exercised in commercial sector as well as 16 frequently adopted simulation tools practiced in research-based area.
