Study Notes

Future of Internet of Things

Projections indicate that by 2018, there could be approximately 20 to 50 billion devices connected to the Internet of Things (IoT).
The anticipated surge in connected devices calls for significant advancements in smart applications.

Addressing Challenges

A major concern is the impending address crunch due to the limited number of IP addresses available with IPv4.
IPv6 has been explored as a solution; however, a new addressing scheme is crucial to manage the growing number of devices effectively.

Connectivity Mechanisms

Various connectivity methods are currently utilized, including:
- Cellular networks
- Wi-Fi
- Ethernet
- Bluetooth Low Energy
- Dash 7
- Insteon
- IEEE standards (802.15.4, 802.15.6, etc.)
Establishing interoperability among these diverse standards is a key challenge, necessitating a robust handshaking mechanism.

Unique Building Blocks of IoT

Concepts similar to traditional internet infrastructure exist within IoT, including:
- LAN IoT (Local Area Network for IoT)
- WAN IoT (Wide Area Network for IoT)
- Node IoT
- Gateway IoT
- Proxy IoT
IoT LAN facilitates local short-range communications (e.g., within buildings or campuses).
IoT WAN involves the interconnection of multiple LANs, highlighting the importance of robust networking solutions in IoT.
