IoT: An Overview
Published in Chintan Patel, Nishant Doshi, Internet of Things Security, 2018
Bluetooth was developed for portable products and offers short range. Bluetooth uses very low battery. Wi-Fi was developed for longer range and consumes high battery. Bluetooth devices consume 1–35 ma while Wi-Fi devices consume 100–350 ma. Bluetooth handles power in two modes: one is stand by and other connection. Wi-Fi have an active mode and a power save mode. Bluetooth uses shared secret and pairing for authentication, while Wi-Fi uses shared secret and challenge response for authentication. Bluetooth makes use of E0 stream cipher, and Wi-Fi uses RC4 stream cipher for encryption. Z-Wave is wireless protocol used in home automation. A smart home network enabled with Z-Wave contains 232 appliances. Appliances can be either controllers or slaves. Z-Wave works on MAC Layer, Transport layer, Application layer and routing layer. Comparatively Zigbee provides better reliability, low radio rebirth, easy usage and easy inter-operability [From (2005)].
Communication Technologies for M2M and IoT Domain
Published in Mohammad Ayoub Khan, Internet of Things, 2022
Z-Wave is a wireless communications protocol used primarily for home automation. An IoT hub or gateway is a key component of a Z-Wave deployment. The hub communicates with the smartphone and/or the communication router to allow access to the home automation devices remotely. The network can support hundreds of sensors, devices, and actuators, which need to send data to a server and/or receive commands for configuration changes or action. The size of the property being managed by a Z-Wave hub can be quite large because Z-Wave uses “mesh network.” Utility powered Z-Wave products act as relay nodes passing the messages along until the destination product is reached.

Z-Wave is the most widely utilized connectivity standard in the context of smart home devices. It makes use of a radio method operating in the 900 MHz frequency. Targeting primarily the home management and automation sector, Z-Wave technology offers a simple and dependable way of wirelessly controlling lights, HVAC (heating, cooling, and air conditioning), safety equipment, and other devices. In order to operate a Z-Wave automation network from anywhere in the world through the Internet, a Z-Wave gateway or central control equipment must be installed, which serves as both the Z-Wave hub operator and a portal to the outside world [43].

In terms of the HAN protocol, Wi-Fi is the most widely used network protocol (used in five companies), based on the IEEE 802.11 standard (Wi-Fi Alliance 2018). However, Z-Wave and ZigBee (used in three and four companies, respectively) are also popular network technologies, which were appropriately developed for HADs. Z-Wave uses low-powered radio frequency with a mesh network (Z-Wave Alliance 2018). ZigBee also uses low-powered radio frequency, and is based on the IEEE 802.15.4 standard (Zigbee Alliance 2017). Insteon has its own network protocol, which is called Insteon. The Insteon network uses both wireless radio frequency and wired power lines, in a mesh network (Insteon 2018b).

Z-Wave technology1 is the other option for data transfer competing with ZigBee in the smart home market. The Z-Wave wireless protocol is optimized for reliable communication of small data packets with data rates up to 100 Kbps. Z-Wave operates in the frequency range around 900 MHz. This band avoids interference with Wi-Fi, Bluetooth and other systems that operate on the crowded 2.4 GHz band. Z-Wave is designed to be easily embedded in consumer electronic devices and systems, such as remote controls, entertainment systems and household appliances.

EPCglobal is a protocol used for RFID systems and is classified into four types depending upon tag type, functionality, and the number of identifiers. LTE-A is a cellular communication protocol where mobiles serve as infrastructure for applications such as the smart city. Z-wave is a low-power wireless communication protocol for Home Automation Networks (HAN). It has 30 meters point-to-point communication, which can be used for smart lights, thermostats, HVAC, among others.
