Please Take An Idea or Do changes
Question 1: How ZigBee is taken as a unique and better wireless technology for the data communication over the internet? [5]
Solution:-
Zigbee technology has many useful features and characteristics and these features of Zigbee technology are the reason of its increase demand in the commercial zone particularly in commercial and residential at time lesser but prospects are better.
Zigbee Technology allows wireless networking to connect several units to control through one button like in business industry. This wireless networking avoids the threat of short circuiting. Centralization control system reduces the man power.
As a wireless communication system Zigbee technology helps to monitor the activities and manipulates in a better way.
Zigbee technology used in the remote control devices helps to control the function at a specific range. This feature of Zigbee Technology is very attractive and effortless as all the home appliances are mostly coming with remote control system which is the essence of this Zigbee wireless technology. In industry all the units are centralized in one place with the help of remote control or switch-based system.
As Zigbee technology based devices are designed on low-power frequency therefore are reliable. Low-power consumption feature of Zigbee technology helps to run a device for a long duration or sometimes this duration is of years.
Bluetooth application gives a unique feature of transferring information or data from one place to another in a far better way than Bluetooth itself.
Zigbee technology is used in three different types of devices which are used in networking according to its functionality. As prominently Zigbee is a wireless technology for making a network system, coordinators are the primary devices to help in activation of the system by collecting the data in form of memory. Then router comes as a secondary device to perform the function by sending information to the destination. Third types of Zigbee based devices are the end-user devices. These are basically receiver so are not able to send information itself. It remains in sleep mode while not in use so less amount of battery uses and resultantly longer life.
Pick ur answer from above
The solution is given as under:
Q1:-
The following are the resons to taken Zigbee as a unique & better wireless technique for data communication over internet:-
It employs a suite of technologies to enable scalable, self-organizing, self-healing networks that can manage various data traffic patterns.
The low cost allows the technology to be widely deployed in wireless control and monitoring applications, the low power-usage allows longer life with smaller batteries
Maximum data rates allowed for each of these frequency bands are fixed as 250 kbps @2.4 GHz, 40 kbps @ 915 MHz, and 20 kbps @868 MHz.
High throughput and low latency for low duty-cycle applications (<0.1.
Channel access using Carrier Sense Multiple Access with Collision Avoidance (CSMA - CA)
Q3:-
Security, data integrity & Reliability are key benefits of the ZigBee technology. ZigBee leverages the security model of the IEEE 802.15.4 MAC sublayer which specifies four security services:
1. access control—the device maintains a list of trusted devices within the network.
2. data encryption, which uses symmetric key 128-bit advanced encryption standard.
3. frame integrity to protect data from being modified by parties without cryptographic keys.
4. sequential freshness to reject data frames that have been replayed—the network.
5. controller compares the freshness value with the last known value from the device.
