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.
