1CRITICAL REFLECTION FOR IOTWireless networks have acquired the entire technological world for the higher rise oftechnology. The high speed and the high range of various applications are the sole reasons forthis type of increasing technologies. The demand of each technology is increasing in everyyear. The users are acquiring the technologies slowly and steadily. ZigBee technology is thespecification of IEEE 802.15.4 and it is the specific suite for the protocols of higher-levelcommunication and thus creating personal area networks or PANs. This is created with thelower power digital radios like data collection for medical fields.Wireless communication is a vast field and has various technologies within it. ZigBeeis one of them. This particular technology of ZigBee consumes extremely lower cost and lowpower[ CITATION Ela15 \l 1033 ].The technology is eventually maintained by the allianceof ZigBee. The particular transmitter in the ZigBee technology majorly comprises of the fourblocks. The four blocks are OQPSK modulator, bit to symbol, CRC and symbol to chip. Thecyclic redundancy check or CRC is the error detection code that is commonly utilized withinthe storage devices and various digital networks for the proper detection of accidentalalterations or raw data. The verification of data is much easier with the cyclic redundancycheck. ZigBee has a significant application in Internet of Things, because of the lower powerand lower data consumption[ CITATION Ela15 \l 1033 ].This technology is perfect for theWSN 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 otherapplication. The recent situation of the various Intranet of Things has evolved into a moreenhanced, integrated as well as heterogeneous system. There are several technical challengesrelated to wireless communication and mobile[ CITATION Zor10 \l 1033 ]. The mostsignificant technical skills for the Internet of Thingsare the heterogeneity, scale,connectivity, privacy, security, self-management capabilities, identification, naming and
