Networks
I NFORMATION that sensors create rarely attains its maximum value at the time and place of creation. The signals from sensors often must be communicated to other locations for aggregation and analysis. This typically involves transmitting data over a network. Sensors and other devices are connected to networks using various networking dev ices such as hubs, gateways, routers, network bridges, and switches, depending on the application.

For example, laptops, tablets, mobile phones, and other devices are often connected to a network, such as Wi-Fi, using a networking device (in this case, a Wi-Fi router). The first step in the process of transferring data from one machine to another via a network is to uniquely identify each of the machines. The IoT requires a unique name for each of the “things” on the network. Intelligent Dashboards Company in Sydeny
Network protocols are a set of rules that define how computers identify each other. Broadly, network protocols can be proprietary or open. Proprietary network protocols allow identification and authorization to machines with specific hardware and software, making customization easier and allowing manufacturers to differentiate their offerings. Open protocols allow interoperability across heterogeneous devices, thus improving scalability.26 Internet Protocol (IP) is an open protocol that provides unique addresses to various Internet-connected devices; currently, there are two versions of IP: IP version 4 (IPv4) and IP version 6 (IPv6). IP was used to address computers before it began to be used to address other devices. About 4 billion IPv4 addresses out of its capacity of 6 billion addresses have already been used. IPv6 has superior scalability with approximately 3.4x1038 unique addresses compared to the 6 billion addresses supported by IPv4. Since the number of devices connected to the Internet is estimated to be 26 billion as of 2015 and projected to grow to 50 billion or more by 2020, the adoption of IPv6 has served as a key enabler of the IoT.
