CRITICAL REFLECTION FOR IOT
Wireless networks have acquired the entire technological world for the higher rise of
technology. The high speed and the high range of various applications are the sole reasons for
this type of increasing technologies. The demand of each technology is increasing in every
year. The users are acquiring the technologies slowly and steadily. ZigBee technology is the
specification of IEEE 802.15.4 and it is the specific suite for the protocols of higher-level
communication and thus creating personal area networks or PANs. This is created with the
lower power digital radios like data collection for medical fields.
Wireless communication is a vast field and has various technologies within it. ZigBee
is one of them. This particular technology of ZigBee consumes extremely lower cost and low
power (Elarabi, Deep, & Rai, 2015). The technology is eventually maintained by the alliance
of ZigBee. The particular transmitter in the ZigBee technology majorly comprises of the four
blocks. The four blocks are OQPSK modulator, bit to symbol, CRC and symbol to chip. The
cyclic redundancy check or CRC is the error detection code that is commonly utilized within
the storage devices and various digital networks for the proper detection of accidental
alterations or raw data. The verification of data is much easier with the cyclic redundancy
check. ZigBee has a significant application in Internet of Things, because of the lower power
and lower data consumption (Elarabi, Deep, & Rai, 2015). This technology is perfect for the
WSN or wireless sensor network and thus it is the future of Internet of Things.
The current status of the Internet of Things is much more important than any other
application. The recent situation of the various Intranet of Things has evolved into a more
enhanced, integrated as well as heterogeneous system. There are several technical challenges
related to wireless communication and mobile (Zorzi, Gluhak, Lange, & Bassi, 2010). The
most significant technical skills for the Internet of Things are the heterogeneity, scale,
connectivity, privacy, security, self-management capabilities, identification, naming and

addressing, energy management and many more. The complexity of the technical problems
for the resource-constrained nature of various components of IoT often is reduced.
