report on WSN based tomato cultivation was presented in paper [
6
]. An automotive irrigation system facilitates the
water management discipline including the control of the water flowing, real time feedback of water level in the storage,
etc. At a 5 seconds interval, the desired data from the farmer comfortable monitoring of agricultural circumstance
become updated to a web server, how a visitor can look after the growing from anywhere.
In view to monitoring the industrial wastewater needed to be discharged, keeping track of potential of hydrogen (pH)
value, oxygen quantity, conductivity, etc., authors demonstrate a cloud unified WSN in [
7
]. It gathers the sensed data in
ThingSpeak, a cloud service, through global system for mobile communications (GSM)/general packet radio service
(GPRS) networking to conduct real time investigation and integration to internet of things (IoT). Telerivet messaging,
a short message service (SMS) notification circulating framework, alerts the occurrence of water pollution to the
respective bodies, appending more benefits to the system.
Countries undergoing rapid industrialization and urbanization are often witnessing an increase in air pollution. Due
to the salvation of hazardous gases, such as carbon monoxide (
CO
), carbon dioxide (
CO2
) and sulfur dioxide (
SO2
),
especially from the industrial establishments, both human health and the environment remain under intimidation over
the years. The aim at [
8
] is to give down a cost and energy effective WSN for looking after the qualities of air in
the environment. The architectures of various components of the system, for example, sensor node, microcontroller,
wireless module, software tool, etc. are detailed in the article. ThingSpeak, too, utilized in this work carries out the real
time data processing to the users. Hierarchical Based Genetic Algorithm (HBGA) set to have an efficacy of the energy,
one of the major Challenges for WSN after the constraint energy of the sensor.
Article [
9
] enunciates a WSN applied noise pollution metering technique’s development proceedings and a noise
hygiene monitoring process. Recently noise pollution concerning vehicles, airplanes, construction apparatus, factories,
electrical devices, etc. has emerged at a menacing level, affecting millions around the world. Sensor’s findings can be
summed in a central database center in order to get real time access to the information required through a graphical
user interface. JTS 13-57 digital sound noise measuring meter including ATmega328 micro controller, GPS, 1.5 Km
transmission capable XBEE are devoted to the architecture of WSN.
Description of a WSN’s development for observing the healthcare’s most pivotal factors is dictated by [
10
]. It incorpo-
rates a centralized node and four sensor nodes, with well instrumented sensing devices, i.e. Humidity, temperature,
CO
,
CO2
, infra-red, etc. sensors. Four sensor nodes and a centralized node need to be equipped in the four patient’s
rooms and the nursing base, respectively in a hospital site. The system is seen to have a root mean squared error of
1.1%, 0.35oC, 0.98% in case of humidity, temperature, and gas, respectively.
The authors provide the article [
11
] with discussing an intelligent method using WSN system for localizing and
estimating boundary of the gas leakage sources in an underground coal quarry. Poisonous and inflammable gases in
the coalmine, for instance, CO, Methane (
CH4
), not only damaging the health but leading to an explosion, rehash
personnels’ life threatening. The concentration magnitude of the area pointed gases is analyzed considering Gaussian
Plume Gas Model (GPGM) to identify the source of leakage, boundary, and gass’ congelation grid map.
[
12
] hosts a representation of the WSN architecture for smart grid that covers the power’s uninterrupted, automated,
and reliable management. Power quality and voltage rising problems was controlled using a dynamic controller. Data
required after being measured on the feeders is provided to a database center through continuously run web server.
WSN can be regarded to be one of the reliable and real time communication systems for military applications, having to
oversee a large remote territory including forces, ammunition, protective weapons, vehicles, etc. [
13
] leaves a WSN
operated military surveillance system to secure the militia bases lying in danger. Nodes’ random deployment and
physical inaccessibility are the two most challenging issues in this case. Hence, the energy effective functions of the
WSN are optimized by an exact node scheduling method.
3 The basic architecture of WSN System
The Open Systems Interconnection (OSI) model, also familiar as Layered Communication Architecture (LCA), is the
most popular architecture adopted by WSN [
14
]. This architecture involves both sink node and source node to take part
into the transmission of data packets.
Materially, OSI/LCA is constructed of five layers, i.e. Application Layer (AL), Transport Layer (TL), Network
Layer (NL), Data Link Layer (DLL), and Physical Layer (PL). Furthermore, three cross-plane layers, such as, Power
Management Plane (PMP), Mobility Management Plane (MMP), and Task Management Plane (TMP) are also integrated
in conjunction with the above mentioned five layers [
15
,
16
]. It is made sense better the concept of a typical WSN
architecture in the figure 1.
PL: It is utilized to produce the interface while transmitting the data packets through a physical channel. The major
tasks of PL are selecting, detecting, and generating frequency. Additionally, electrical and mechanical interfaces are
also described by this layer. IEEE 802.15.4 standard is intended in regard to the layer to prolong the lifetime of the
batteries considering lower energy consumption and cost, simplicity, and communication range etc. for a WSN system
[17].
