Thus all devices of the protocol can interact. ZigBee ensures that networks remain operable in the conditions of a constantly changing quality between communication nodes. ZigBee standard defines a multilayer structure of software. Usually this is called ZigBee protocol stack. Despite the declared simplicity ZigBee stack is not much simpler than TCP/IP protocol stack for small-class add-in devices.It is very costly to purchase the stack in source texts. The stack is usually offered in the form of compiled libraries, also at high prices.
The ZigBee IP specification enriches the IEEE 802.15.4 standard by adding network and security layers and an application framework. ZigBee IP offers a scalable architecture with end-to-end IPv6 networking, laying the foundation for an Internet of Things without the need for intermediate gateways.
