Introduction:
WiMAX or Worldwide Interoperability for Microwave Access is a coalition of the
wireless industry for the advancement of IEEE 802.16 standards for broadband wireless access
(BWA) networks. WiMAX (Pareit et al., 2012) is commonly known as 4G network and is a
wireless wide area network (WAN) that can cover the area same as DSL lines but without wires.
3DES (Data Encryption Standard) (Singh, 2013) and AES (Advanced encryption standard)
(Ahmad & Ismail, 2016) is used by WiMAX to encrypt the data transferred on the network. The
3DES uses three different keys to encrypt the data. Each data is of the length of 56-bits each. In
some software’s the performance becomes slow due to the use of this three keys. The 3DES is
becoming obsolete due to its slow performance and the limit of length of the keys. Advanced
Encryption Standard (Rewagad & Pawar, 2013) is the main tool used for encryption in WiMAX
technology. Encryption key of 128-bit, 192-bit and 256-bit is supported by the advanced
encryption standard. AES is a popular algorithm which was built from CCMP. 3DES is much
slower than AES. Advanced Encryption standard is much more easy to implement and a very
little memory is used. However, AES does not require dedicated processors on board the BS, and
m their might be a risk of not being used by all end-user terminals. Initially this helps in
considering the fact that 3DES still remains a vital encryption tool on the WiMAX (Dadhich,
Narang & Yadav 2012) network in spite of the presence of advanced encryption standard.

Disadvantages of WAPN technology:
The most common WAPN technology are the Bluetooth and the ZigBee network. Both
this technology faces the same difficulty as that of the security issues faced by the wireless
technology.
 Problems faced by Bluetooth technology are listed below:
 Eavesdropping – This is a process by which an attacker can sniff into the air of Bluetooth
transmission and exploit the right vulnerabilities, read or listen to the data (Saliou et al.).
That means someone is conversing using a Bluetooth headset then someone can
potentially listen to it.
 Bluesnarfing – This is a process in which an attacker can pair to a device and once
devices are paired, access and steal information from the Bluetooth device becomes very
easy. The pairing is usually done without the knowledge of the user, which
possibly results in stolen contact information, photos, videos, calendar events, and more
(Ketari & Khanum, 2012).
 Blue bugging- An attacker can easily remote control the various aspects of the user’s
device. Sending of outgoing calls and texts, forwarding of incoming calls and texts,
change of settings, and watching of screens and keypresses and many other things (Rawat
& Bhattacharya, 2016).
 Denial of service –in this process an attacker can put unwanted stuffs in the user’s device,
block the communications, drain the battery of the device, or even crashes the device.

 Problems faced by ZigBee technology:
 Sniffing: there are many networks which do not use proper encryption as a result the
attackers take advantage to sniff all the communications with the proper use equipment’s.
in this attack all the information from a network is collected, which is possible in a
network which implements the standard generic security level protocols for
communication (Olawumi et al., 2014).
 Replay attack: This type of attack is a key based attack where the attacker records the
approved traffic on a network and paly it later which causes a malicious effect. This
attacks are straight forward for ZigBee’s which do not implement a do not implement any
encryption for the communication (Vidgren et al., 2013).
 Physical Attacks: this type of attacks are most common and involves the tampering of
ZigBee devices by locating it. Hard coded encryption keys which are loaded in the RAM
are often employed by radios operating in the ZigBee network once the device is
powered.as the devices in the network are disturbed and flashed so there remains a
possibility of replacing the keys becomes less and having known the issues the attackers
can set up special serial interfaces in order to intercept the encryption key in the ZigBee
device when the power rises from flash to RAM (Ramsey, Mullins & White, 2012).
 Denial of Service-There are many other methods along with the one mentioned above
thereby making ZigBee network unsafe. Signal jamming, reflexive jamming,
maximization of frame counter are some other problems faced by the network (Bahl,
Sharma & Verma, 2012).

Energy Harvesting
1. Faisal Karim, and Sherali Zeadally. "Energy harvesting in wireless sensor
networks: A comprehensive review." Renewable and Sustainable Energy Reviews
55 (2016): 1041-1054.
This article discusses about the energy harvesting techniques used in daily lives.
Energy harvesting is one of the emerging technology related to applications on indoor and
outdoor environment. The demands for energy harvesting as increasing with the
advancement of microelectronics and MEMS. This rep article also discusses about the
problems and applications of energy harvesting. This has gained the attention of various
stallholders which involves designs and implementation of this technology to face the energy
demands of future wireless sensor networks. Moreover, this article focuses on the techniques
required to meet the future energy demands of the WSNs. Specifically, this focuses on the
classifications of the schemes used on energy harvesting techniques in WSNs. The article has
thoroughly reviewed the classes and sub classes of energy harvesting techniques and the
harvester mechanism along with the efficiency of the harvester. For each category the
harvester hardware system has different design and has different harvesting capabilities. The
different designs of the harvester determine the efficiency of the harvester. A survey has been
conducted on various models aimed to predict the future energy cycles. The survey has
proved that only few predictions technique has been used still far to in the area of modeling
which states that the state-of-the-art is still immature. It has also been found that several open
research challenges still need to be addressed in the future which includes the need to focus
on the miniaturized generic harvesters. This can later be used in different environments with
dynamic energy sources. The major reason for deploying energy harvesting technique is due

to the major problem faced by WSN regarding energy. In cases if the energy of a sensor node
depletes then it no longer plays its role unless and until a new source of energy is used or
some harvesting technique has not been introduced to fulfill the energy gap.

recent advances." IEEE Journal on Selected Areas in Communications 33.3 (2015):
360-381. 4.
This article summarizes the application of energy harvesting in a broad area of wireless
communication network. This article has covered a variety of topics which includes the
information-theoretical and physical layer of performance limit to the scheduling policies and
medium access control protocol. This article also discusses about the emerging model of energy
transfer and cooperation that occurs with the information transfer of the wireless network. The
article has also presented a model of total energy consumption. The threats faced by energy
harvesting from physical and practical concerns has made this technique face new challenges.
Taking practical conditions mathematical formulas are designed which increases the set of
possibilities. The discussion of the energy and information transfer provides exciting possibilities
that can be adapted in the future to adapt the network operations with improved performance.
