Can you explain the role of IP in IoT/M2M -IOT

Question 1: Can you explain the role of IP in IoT/M2M?

My device is useless without an addressable IP – This is possibly the biggest misconception around IP addressing in M2M. Yes being able to address a device when needed is useful, but there are literarily millions of devices that function just as well by initiating communications remotely without needing to be poked or prodded by you or your server.

 

Question 2: Can you explain the differences of IPv6 address types?

 – To most people involved in IP networking, especially in the M2M space this has been the Holy Grail for the past 3 years but in reality there is still some way to go from a hardware and network architecture perspective for it to be commonplace. I know the IoT is going to be a big factor in driving IPv6 uptake but from a cellular M2M perspective it’s all IPv4 all the time… for now.

 

Question 3: Can you explain the ways to transit from IPv4 to IPv6?

Dual-stack

When switching from IPv4 to IPv6, this is one of the simplest ways to utilize. Install any router with both IPv4 and IP6 address on its interfaces, and then point the network to the appropriate IP scheme. A dual-stack router can communicate with both IPv6 and IPv4 networks at the same time.It provides a framework for hosts to connect to a server without having to change their IP versions. Many organizations, however, find that IPv6 does not operate on all of their IPv4 equipment. This necessitates the examination of alternative transition methods.

 

Question 4: Can you explain why IPv6 cannot be applied directly to IoT/M2M?

Abstract IPv6 is the most promising protocol for complex and distributed network applications in the era of the Internet of Things and Industry 4.0. However, its industrial adoption, in particular in smart manufacturing systems, has been much slower than expected. Although the potential advantages of IPv6 for the industrial internet of things are well-known, it is not easily usable in practice. In this paper, we present a qualitative evaluation of IPv6 for the industrial internet of things. We have conducted expert interviews with five industrial IPv6 users. Our key results indicate that the major problems are threefold: First, tool support and existing libraries are incomplete or immature. Second, users still often have to manually configure the IP communication. Third, there are complicated one-fits-all protocols prevalen

 

Question 5: What is 6LoWPAN?

The 6LoWPAN system is used for a variety of applications including wireless sensor networks. This form of wireless sensor network sends data as packets and using IPv6 - providing the basis for the name - IPv6 over Low power Wireless Personal Area Networks.6LoWPAN provides a means of carrying packet data in the form of IPv6 over IEEE 802.15.4 and other networks. It provides end-to-end IPv6 and as such it is able to provide direct connectivity to a huge variety of networks including direct connectivity to the Internet.In this way, 6LoWPAN adopts a different approach to the other low power wireless sensor network solutions.
