Literature Review
These days individuals are progressively reliant on the Internet to direct their day by day
exercises. Because of this, there has been a rise in the use of the Internet of Things (IoT).
Subsequently, it has essentially expanded the gadgets associated with the Internet; stretching
around of 20 billion associated gadgets, and is relied upon to achieve 50 billion out of 2020. This
has made extraordinary difficulties for keeping up security and protection of data on the grounds
that most cell phones center around availability and are including default settings where security
is extremely influenced. This paper introduces the outcomes got by the convention of precise
audit to set up the present condition of security in IoT gadgets. The fundamental concerns,
dangers, assaults, difficulties, and a few countermeasures have been highlighted
Introduction
Internet of Things (IoT) is a representation of a universal idea for the capability of
devices that are connected in a network to detect and gather the data collected from our
environment, this collected data then is sent through the internet and thereafter it is used in
different fields as explained in [1].
A “thing” in the Internet of Things can represent a vehicle fitted with an automatic speed
sensor which sends alerts to the driver on the speed status, a person implanted with a heart sensor
recording and sending the condition of the heart or any of the man-made or natural objects that
are given abilities to send data through a network.

Characteristics of the Internet of Things compared to the traditional network
Intelligence
Internet of Things is smart devices since they have a collection of calculations and
algorithms, hardware and software according to the work in [2]. The intelligence in this IoTs
raises the abilities which enable the objects to intelligently respond to a given condition and
aiding in doing those particular tasks. In contrast to traditional networks, IoT devices such as
automated vacuum cleaners do their work independently due to the intelligence. IoT intelligence
in specifically referred as a way of interaction among the devices even with the advancement in
smart technologies. Graphical user interface and any other input ways that are standard are used
in the interaction between the user and the devices.
Connectivity
Internet of Things is empowered by the connectivity that brings together daily life
objects. The connectivity between these object is important because primary object level
fundamental interactions promote corporate intelligence in a network of the Internet of Thing [3].
It facilitates the compatibility and accessibility of the network. Vehicles fitted with automatic
speed sensors are able to connect and send the speed status to the authorities over the internet,
unlike the traditional networks which would have just stored than to be read manually or to be
sent by the user.
Sensing abilities
Sensing capabilities is a crucial component of the Internet of Things which does not exist
in traditional networks. The work in [4] states that IoTs are equipped with sensors to detect any

disparities in the surrounding and provide information about the status of that given environment.
Technology in sensing gives a way to come up with abilities reflecting an awareness that is true
about the people and the real world. For instance, sensors implanted on an organ like the human
heart which gives information such as the heart beats.
Heterogeneity of IoTs
Heterogeneity is the ability of Internet of Things to interact with other devices that have
different hardware and software programs over various networks. The architecture of the IoT
must be design to support devices connected to a network directly amongst the heterogeneous
networks. This capability may be present in traditional networks where most of the only
compatible with some selected networks [3].
Application areas of Internet of Things
Application of IoT on Healthcare
Internet of Things is getting useful in the field of Healthcare such as surveillance of
patients, detection of fall, care of sportsmen, medical fridges among others applications. For
example, the fall detectors will assist the elderly and the disabled who live on their own [6]. This
will reduce the medical issues and increase the joy of being healthy. In the near future, IoT will
provide a device that takes the measurements of Ultraviolet rays of the sun to reduce the
infection from this kind of pollution.
