Thank you guys, I finally get it....6LoWPAN sounds fancy but it really is IPv6, just re-packaged for wireless area networks...kind back to my point of IPv6 being sufficient for IoT ;-)...Kris

For sensor to send packet to the "gateway", 6LoWPAN, i.e. iP over IEEE802.15.4, makes sense. It saves time on building interconnected infrastructure. Once the packet reaches gateway, the packet will then be decompressed. Ultimatedly, an uncompressed IP packet will be sent to the cloud in whatever mechanism that is defined. For delay tolerant application, I highly suspect the transport layer will stay with TCP. Higher layer can be REST API or SOAP.

Krisi, this is IPv6 over IEEE 802.15.4, instead of over Ethernet. Read all about it.

So yes, the comment that IoT would use IP is almost a given. Else, it wouldn't have been called *I*oT.

Bert, I agree with you here with a caveat -perhaps Uncle Sam thinks that it can replicate the success it spawned with ARPANet project leading to the modern-day Internet. Such a premise in this context is largely misguided because IoT has progressed without any government initiatives.

IoT will proliferate because of necessity and not by the 'coolness' factor.

The optimization is actually in the packet size. It is IPv6, but the addressing is shorthanded through the use of a local address table. I believe they also do message compression. The idea is to get the full networking capability of IPv6 without the larger messaging overhead.

thanx...how much smaller is it? TCP/IP packet is not that large

Low power, Krisi. It's lightweight by design: the header, packet size etc. are smaller. It was designed for low power i.e. IoT applications. It makes sense for battery-powered things.

There is COAP for that, Larry.

PS. Yes, 6LoWPAN is a cut-down version of TCP/IP.

Larry, what is the advantage in using 6LOWPAN over plain TCP/IP? I am having hard time understanding why we need a different protocol stack for IoT. TCP/IP is like English lanuage for international talk, sure you can speak some other dialect but why? Kris

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
