That is a very good question and actually my current research topic. I try to give an adequate but concise answer¹. I will focus my answers to networks based on the IEEE 802.15.4 standard (Zigbee and 6LoWPAN both use it as physical and data link layer) as well as networks where most traffic goes through a common gateway. Most arguments also hold for peer-to-...

In any case, a 6LoWPAN enabled Sensor Network needs a Gateway to interact with an end user who might be using a standard 802.11 WLAN or a 802.3 Ethernet based network. The Gateway needs to translate the 6LoWPAN enabled IPv6 addresses into addresses that standard networks can understand and communicate. For instance, if a node with 6LoWPAN enabled on it ...

Thread is a 6LoWPAN-based protocol which is starting to get some adoption by manufacturers. As noted on their website, it's backed by various companies such as Nest, Yale, ARM and Qualcomm and is probably the most likely candidate for any 6LoWPAN implementations in future in the smart home. So far, adoption hasn't been great though. Their website advertises ...

If you consider that the internet is a mesh network of sorts, you should see your answer in the broadest terms. Asking is a specific mesh network has any scalability issues is slightly different. There is plenty of scope to architect a modified network protocol to address a specific implementation, with the right sort of optimisations. At some point, you ...

The RFC draft explains a bit better how the header compression works. What is described as arbitrary prefixes in the abstract is essentially a bunch of information that is assumed to be in a certain range or having a specific value. Thus, making transmitting those information unnecessary. To enable effective compression LOWPAN_IPHC relies on information ...

I think you will find modules without too much trouble, there have been chips around for over a year that I found (and there is a module on Kickstarter which looks like a simple small production run sales testing exercise). A 6LoWPAN to 3G gateway is probably a bit of an esoteric use case - any you can find will be built-in to an end product, so it might be ...
