Dear folks,

Elderly person health is an = important issue these days, especia= lly in the case of the elderly person do not live together with their chil= dren. 
IMO, = fall-detection system for elderly person monitoring may be contained = in home network, together with telemedicine, home safety equipment and so on. So home users = can take care of them in an intelligent and automatic way= to improve their quality of life. 
E= ach device or system can be accessed and controlled independantly not only= via home network but also via the Internet for conv= enienceSo, each devices= may have a special ID and can be accessed through IP->ID via Internet.= Thoughts?


regards

That indeed seems a good target for 2020. With a 10-15 year horizon, I'm probably more comfortable with "hundreds" than with "~250" as an upper bound... (~250 is probably fine as a per-technology upper bound, as used in G.9959, for quite a while.)

Whether you have a 100 or 10,000 devices doesn't make so much of a difference if they are silent all the time. +1 on avoiding strict upper bounds (640 KB should be enough for everybody and 32 bit IP addresses suffice) Jörg On 22.04.2015 15:33, Simpson, Robby (GE Energy Management) wrote: > I too am generally uncomfortable with upper bounds. I think a more interesting exercise would be enumerating what we believe would create limits/constraints (e.g., addresses, specific buffers, connection overheads) from a research group perspective and then determining what bounds may result.

We had a discussion about the need for cooperation between IETF/IRTF and W3C on the common subjects of IoT/WoT. Without trying to summarize the entire discussion here (I'm sure there will be minutes), it seems there are at least two areas where some immediate interaction between the two groups will be of common benefit: 1) Interaction patterns. How do the various nodes and entities in an IoT/WoT environment interact? Which of these patterns are covered by REST as implemented in the two HTTP protocols and in CoAP, and how well? Where are gaps? (There is probably little point dwelling too much in solution space here, but solutions that come with clean architectural styles are of interest.) While the IETF doesn't usually deal in APIs, some common effort in describing the interaction elements in APIs (including browser APIs) will help. 2) Security that enables these interaction patterns. One example is browser support for REST, which is currently more limited than one would want for reasons of lack of security. Security models that derive security properties implicitly and based on assumptions (which may be more valid in one domain than in another) get in the way (say, same-origin as implicit authorization). If explicit security, as e.g. enabled by ACE, becomes more available, what can be simplified, and what additional powers do we gain? The next face-to-face meeting of W3C IG WoT is being planned in the US, for similar reasons that we had our first meeting in the US (rotating regional coverage). Nonetheless, we are looking to set up a meeting in Prague that is sponsored both by the W3C IG and the IRTF RG, on the two days before IETF93: Saturday 18th/Sunday 19th of July. The main focus of that meeting will be on the above two areas, but that of course doesn't rule out other subjects, in particular if they can be of interest to both IG and RG. So, please save the date, and do follow up with specific topics you want to contribute to in that meeting.

Hi,Ciao, thank you very much for your suggestion.

Cloud-based service may be a good way to access the IOT dev= ices for users.=0AIn this case, Users may get the data uploaded or shared = by other users/services. 
But,how do the various nodes and entitie= s in an IoT environment communicate with each other? 
 IMO,each IoT device has a special "name" , the user= s/devices can communicate with each other using the "name". Like DNS, the= =E2=80=9Cname=E2=80=9D can transform to IP address for accessing via Inte= rnet.

Recently, we also had to go through a scenario guesswork for a home automation evaluation. (We didn't use an actual home setting. Instead, we emulated a home by assigning specific roles to nodes in a testbed.) Part of the guesswork included the traffic patterns. Hoping that this can be useful, the node roles and traffic patterns we assumed can be found in sections 4.1 and 4.2 here: http://www.mdpi.com/1424-8220/14/8/14932. RFC 5826 also provides some details on expected traffic patterns in the same space: https://tools.ietf.org/html/rfc5826#section-4 Best regards, Carles
