WIRELESS NETWORKING CONCEPTS
Answer 1
WiMAX or Worldwide Interoperability for Microwave Access is an IEEE 802.16 set of
standards based standard of wireless communication. It provides options for controlling multiple
physical layer and media access. The three encryption standards that is used by WiMax
technology is triple DES or 3DES, AES and RSA. The triple data encryption standard makes use
of three different encryption keys, each of 56 bits for encryption. In AES or Advanced
Encryption standard the keys of 128-bit, 192-bit or 256-bit encryption keys are used for
encryption. RSA or public key encryption technique that makes use of both public and private
key decrypting and encrypting a particular input, is used in WiMax as well. The comparison
among the different WiMax technologies is as follows (Singh, 2013)-

Definition 3DES is asymmetric
block cipher that applies
DES algorithm 3 times
in an input in order to
encrypt a data (Adhie et

block cipher that makes
use of 128bits block

Answer 3
With the emergence of wireless networking, there has been a constant increase in
adoption of long range applications that have high speed. The demand of these technologies has
considerably increased over the years. The popular demand to develop networking of low power
and low data has resulted in the formation of Zigbee technology. Not only the wireless networks,
but also the use of internet of things has considerably increased. However, there are certain
challenges associated with the use of Internet of things (IOT) and wireless. The challenges
associated with the IOT and wireless technology can be mitigated by taking proper measures.
Zigbee is one of the most widely adopted wireless communication technology. It is an
application specification for high level of communication, which can be achieved in a very low
power and low cost. The technology of Zigbee is based on IEEE 802.15.4 standard for the
Personal Area Network (Elarabi, Deep & Rai, 2015). Zigbee alliance maintains the Zigbee
technology. A transmitter in Zigbee mainly consists of four blocks, which are CRC, Bit-to-
symbol, Symbol,-to-chip and O-QPSK modulator. The error detection technique of cyclic
redundancy check is associated with the Zigbee technology in order to evaluate the error in the
codes. Addressing the error in the codes is essential for reducing the data security risks
associated with the use of Zigbee.
The main aim of IOT technology is to connect the smart things together in order to
provide a chance for enabling a rich set of evolutionary along with the revolutionary applications
and the services (Zorzi et al., 2010). Further researches in the field of IOT can make it possible
to interact or communicate with the environment, in order to receive the information in its status.
IOT is a new and emergent technology as the term was coined more 10 years ago. From that

time, there has been a considerably research and studies associated with the use of internet of
things. However, one of the key elements that can possibly make the IOT paradigm successful is
its ability of integration of different types of devices, technologies and services.
