Analysis of a Research Article on Vehicular Ad Hoc Networks (VANETs)

This report provides an analysis of a research article focusing on Vehicular Ad Hoc Networks (VANETs). The article begins by describing the VANETs architecture, including network components categorized into mobile, infrastructure, and generic domains, and communication types like in-vehicle, V2V, V2I, and V2B. It highlights key research issues such as routing, security, and privacy, along with applications and research methodologies, including mobility models and simulator tools. The analysis also covers challenges and future trends in VANETs research. The report then critically examines the research methodology, noting the lack of original models and empirical validation, which affects the credibility of the research. The report emphasizes the need for original approaches and experimental validation, particularly given the safety-critical nature of VANETs applications.

ANALYSIS OF THE RESEARCH ARTICLE
Summary of the article:
The article has first described the VANETs architecture, which considers network
components, communication types, and another important aspect that is layered network
architecture.
According to the article, the main network components are divided into three important
domains: which are the mobile domain, the infrastructure domain, and the generic domain.
The mobile domain consists of the vehicle domain and the mobile device domain. The
vehicle domain includes different type of vehicles such as cars and buses. The mobile device
domain includes different type of portable devices which consists of personal navigation
devices and smartphones.
The infrastructure domain as described in the article, consists of two domains: the roadside
infrastructure domain and the central infrastructure domain. The roadside infrastructure
domain includes roadside unit entities for example traffic lights. The central infrastructure
domain contains components related to infrastructure management centers which consists of
traffic management centers (TMCs) and vehicle management centers.
In VANETs, types of communication are categorized into four types.
In-vehicle communication, belongs to the invehicle domain. In-vehicle communication
provides context for detecting performance of a vehicle, specifically driver’s fatigue and
drowsiness, which has a significant role in driver as well as public safety.
Vehicle-to-vehicle (V2V) communication allows drivers to exchange data so that they are
capable of sharing information which includes warning messages, to ensure a comprehensive
driver assistance.

ANALYSIS OF THE RESEARCH ARTICLE
Vehicle-to-road infrastructure (V2I) communication is considered as a beneficial research
field in VANETs. V2I communication allows to provide traffic/weather updates in real times
for drivers. Along with this it also allows environmental sensing and monitoring.
Vehicle-to-broadband cloud (V2B) provides context to communicate through mechanisms
applied in wireless broadband for example, 3G/4G. The broadband cloud which is capable of
storing more traffic information along with traffic monitoring data this type of
communication might be considered for providing effective driver assistance as well as
vehicle tracking.
Then the article has described that there are three aspects of issues of VANETs research
which are routing, security, and privacy, as well as applications of the architecture. The
article has provided a comprehensive discussion on VANETs research methodologies and
along with this some mobility models is also provided to provide a detailed idea how the
authors have conducted the research. Simulator tools that are considered for this research are
provided as well. Finally, an analysis is provided on challenges regarding VANETs research
along with future trends. This author has introduced the vehicular ad hoc networks from the
research point of view, and it includes basic architecture, critical research issues, and general
research methods of VANETs, and offers an inclusive reference on vehicular ad hoc
networks.
Analysis of the research methodology:
The authors have first introduced different models for implementing research methodologies
in VANETs. Along with discussion on these models, the authors have also provided
procedures for the simulations and field operational testing. The authors have only discussed
about general methodologies that are discussed in different literary articles and research
papers by previous researchers. However, the authors have not provided any original model

ANALYSIS OF THE RESEARCH ARTICLE
and no experiment was conducted for evaluation of the models discussed. Therefore no,
empirical validation was not provided and this affects the credibility of the research.
Implementation of VANETs architecture is a complex process and therefore in this context
an original approach is required for ensuing that the approach considers the issues and
provide strategies for ensuring that the implementation of VANETs is effective and efficient
as well. This type of application involves safety of drivers and passengers and therefore
requires analysis of the proposed model for identification of issues in the model and for this
experimental validation is required. However, such approach was not followed in this
research as described in this context.
