- Smart initiatives – providing a centralized view of yet unrealized volumes of data for more intelligence resource management and customer service such as:
- Smart Grid – Dynamic matching of electricity, water, gas, etc. supply with demand, reducing resource waste and saving consumers on utility bills.
- Smart Cars – Diagnostic and usage sensors within an automobile for performance reporting, troubleshooting and customer notification of worn components and recommended service check-ups as well as automated crash detection and reporting.
- Smart Homes – Remote monitoring of premises, smart appliances, remote control of power, heating/cooling, lighting, entertainment, and access.
- Municipal (smart cities) and industrial surveillance and monitoring – physical access control and monitoring, environmental monitoring for extreme conditions (e.g., natural disaster, fire, floods), structural monitoring and traffic monitoring.
- Field applications – fleet management, dispatch, tracking and vehicle telematics.
- Healthcare – fitness tracking, remote monitoring of patients’ vital signs, diagnostics and medication administration, “body area networks,” monitoring of storage environments, e.g., for plasma, organs.
- Industrial – factory line monitoring, diagnostics, resource control, supply chain management, process monitoring and control leveraging improved accessibility that wireless provides.
- Military – battlefield ad hoc networks with various soldier sensors reporting status updates to military command.
IPv6 is likewise an enabler of IoT in one sense by its sheer address capacity in supporting millions of things (tens of billions by 2020 according to many analysts). When IoT devices are deployed within the confines of an enterprise network for use in internal network applications such as factory automation, surveillance, etc., use of private IPv4 space could provide sufficient address capacity depending on the quantities of things and existing allocations of private space. When public IP addresses are required by things, to literally connect to the Internet, IPv6 addressing may become necessary if not the default, given the general lack of available public IPv4 address space.
Beyond address capacity, certain applications may require ad hoc networking capabilities where things may require address autoconfiguration to “self-initialize” on the IP network or Internet based on local access connectivity. If Dynamic Host Configuration Protocol (DHCP) servers are not provisioned, the stateless address autoconfiguration (SLAAC) feature of IPv6 enables things to detect local network addressing and to auto-assign their IPv6 addresses.
The IPv6 SLAAC feature provides automation with agility for ad hoc Internet access, though it raises potential network access control concerns from a network manager’s perspective. In such cases, provision for security, access control and IP address management (IPAM) solutions becomes critical. IPAM solutions that can detect IPv6 addresses provide visibility into ad hoc IoT devices for network managers, while corresponding security solutions enable qualification and access control for connected things. I’ll discuss these topics in more detail in a future post.
