ECHONET Lite as a smart home standard. 920IP is the only standard referenced
by the Telecommunications Technology Committee (TTC) which supports multihop mesh networking.
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. It offers a cost-effective
and energy-efficient wireless mesh network based on standard Internet protocols,
such as 6LoWPAN, IPv6, PANA, RPL, TCP, TLS, and UDP. It also features
proven, end-to-end security using TLS1.2 protocol, Link Layer frame security based
on AES-128-CCM algorithm and support for critical public infrastructures using
standard X.509 v3 certificates, and ECC-256 cipher suite. ZigBee IP enables lowpower devices to participate natively with other IPv6-enabled Ethernet, Wi-Fi, and
HomePlug devices.
From this foundation, product manufacturers can use the ZigBee Smart Energy
version 2 standard to create multi-vendor interoperable solutions. As with any
ZigBee Alliance specification, custom applications, known as manufacturer-specific
profiles, can be developed without multi-vendor interoperability.
Characteristics of ZigBee IP include:
• Global operation in the 2.4 GHz frequency band according to IEEE 802.15.4
Regional operation in the 915 MHz (Americas), 868 MHz (Europe) and 920 MHz
(Japan)
• Incorporates power saving mechanisms for all device classes
• Supports development of discovery mechanisms with a full application confirmation
• Supports development of pairing mechanisms with a full application confirmation
• Multiple star topology and inter-personal area network (PAN) communication
• Unicast and multi-cast transmission options
• Security key update mechanism
• Utilizes the industry standard AES-128-CCM security scheme
• Supports Alliance standards or manufacturer-specific innovations
3.3.7 WirelessHART
WirelessHART is a wireless extension of the Highway Addressable Remote Transducer Protocol (HART) [33] used in factory automation and process control. In April
2010, WirelessHart was approved by the IEC as the wireless international standard
IEC 62591-1. Figure 3.16 shows a complete example of WirelessHART architecture
which includes:
• field devices performing field sensing or actuating functions;
