XMPP-based approach for IoT platform Commissioning and Network Management

by CONZON DAVIDE

Hi all, during the last 30 months I have been involved in a project called IMPReSS ( http://impressproject.eu/ ) co-funded by both European Commission, through 7th programme framework, and Brazilian government, through the CNPq minister. The aim of the project, which is on the eve of the final review, is to provide a Systems Development Platform which enables rapid and cost effective development of complex systems involving Internet of Things and Services and at the same time facilitates the interplay with users and external systems. Leveraging XMPP protocol, the project developed a Network Management infrastructure and Commissioning and Configuration infrastructure for IoT platforms. The latter supports the configuration and mashup of the different components of the IoT platform, while the Network Management infrastructure provides instruments for network monitoring and setup. This infrastructure leverages many features provided by XMPP protocol: - every device is uniquely identified through a Jabber Identifier (JID); - the presence mechanism is used to know in real-time the status of the devices; - XEP-0030 (Service Discovery) is used to discover the entities and their feautres; - XEP-0050 (AdHoc Command) and XEP-0060 (Publish-Subscribe) are used to model the device capabilities in term of data generated and services provided; - XEP-0248 (PubSubCollection Nodes) is used to organize the publish-subscribe nodes, modeling the devices and their features,in a hierarchical structure. which can be used in the discovery mechanism As a next step, we are aiming at making this solution to converge toward XMPP-IoT extensions specifications, with a particular interest and focus on XEP-0324: Internet of Things - Provisioning, which will allow us to improve furtherly our commissioning infrastructure to help people with non-programming skills to quickly and easily develop IoT application based on general purpose IoT middlewares and platforms. This XMPP infrastructure has received good feedback and interest at ICIN 2016 conference on ‘Innovations in Clouds, Internet and Networks’( http://www.icin.co.uk/ ) where has been presented. If you are interested in extended information, you can find the presented paper at the following link: https://www.researchgate.net/publication/299445607_XMPP-based_Network_Manag… and relevant slides here: https://www.researchgate.net/publication/299594851_Slides_XMPP-based_Networ… Hope you can find this approach interesting for you.

Global IoTday 9th of april

by Joachim Lindborg

Hi all next saturday it's global IoT day http://iotday.org I will again have a session in Stockholm where we will do some hacking, talk about IoT compare protocols and technologies and of course use xmpp-iot. *The idea is to use XEP323 and XEP 325 with basic read and write between IoT devices* *http://http://www.xmpp-iot.org/tutorials/ <http://www.xmpp-iot.org/tutorials/>* *http://www.xmpp.org/extensions/xep-0323.html#readmomentary <http://www.xmpp.org/extensions/xep-0323.html#readmomentary>* *http://www.xmpp.org/extensions/xep-0325.html#sect-idp1718128 <http://www.xmpp.org/extensions/xep-0325.html#sect-idp1718128>* *We will talk between JID's subscribed to each outer so devices need to accept subscription requests either from anybody or if you prefer specific servers. * *We will also use one chat room for discussions * *We will use another chat room for devices to have anonymous direct messaging. So no groupchat talks in that room only direct messaging between nicknames, otherwise it would easily be totally swamped.* So I would like all of you, that have a device or two, to hook them up and publish a JID and we try to do an "around the world federated IoT hack with the best open 'IoT Silo' killing standard, XMPP. If you have any other suggestion on usage, pubsub, adhoc, testcases, servers, etc etc lets talk about it and see where we get. *Regards* Joachim Lindborg CTO, systems architect Sustainable Innovation SUST.se Barnhusgatan 3 111 23 Stockholm Email: Joachim.lindborg(a)sust.se linkedin: http://www.linkedin.com/in/joachimlindborg Tel +46 706-442270

Re: [IOT] IANA application

Hello Peter, Joachim and Dave (& others). Thanks for the input. > tror du beh?ver uppdatera adresser etc i > https://www.iana.org/assignments/uri-schemes/prov/iotdisco det l?r v?l inte > komma fram post till valparaiso? och din mail fungerar ju inte heller. Regarding address in application: Yes, it points to my old address in Chile. I learnt that I was to move back after sending the application. A request to update the contact information has been sent. Let’s see how long that takes… > jag reagerade p? att version skall vara numeric med decimalpunkt men m?nga > k?r ju major.minor.patch https://wiki.eclipse.org/Version_Numbering vilket > eg blir string? You could also report the version number as two or more parameters. The point here is to make searching more simple. For instance, you want 1.10 to be greater than 1.2, which it is if numeric, but not if a string. This makes it possible to search for temperature sensors of brand X, model Y with a version number greater than Z. You could add a patch parameter (or build parameter) to include more detailed information if you want. > I find this slightly unfortunate, because XEP-0053 reads: > > The XMPP Registrar shall be responsible for interacting with the > IANA on behalf of the XMPP Standards Foundation.

Correct. The work on this was part of the IEEE WG. I also mailed the iot list (and others) for comments, but received them a bit late. > What exactly is the relationship between this URI scheme and XEP-0347? XEP-0347 proposed a method (in §3.9) where metadata could be encoded as a string, and then encoded as a QR-code (as an example). In the IEEE WG, they did not like the fact that the string was not encoded as a URI. So, we created another encoding based on similar principles, but that has a URI scheme and valid URI syntax. This encoding is better, and the URI scheme is registered. The idea is to update XEP-0347 to reflect this change. It also makes it easier to integrate into software scanning QR codes to know what the code is supposed to mean. > Yes, Peter Waher's postal and email address, as listed, doesn't work > anymore, does it?

IANA application

by Peter Waher

Hello During the work in other standards groups, there has been some interest in the discovery model presented in XEP-0347. This has lead to the desire to update the IoT-discovery encoding described in the XEP somewhat and formalize it into a URI scheme. I've therefore prepared an application to IANA for a provisional URI scheme. The idea is to send it by the end of next week. So, if you have time, and an interest, you're welcome to return any comments, suggestions or questions to me by then, so I have a chance to update the application before mailing it. The idea is to update XEP-0347 after the approval of such a provisional URI scheme. Best regards, Peter Waher

COAP as Streaming Source

by Sadaf Khan

Hi i am working on coap protocol for an Iot Application .I' ve made this as a Spark-Streaming Source. i simply 've made a resource and add it to my server as a observable resource. then i start observing it through myclient, It fetches the data perfectly but also gives the following exception. 15/10/14 13:49:48 ERROR BlockGenerator: Error in block pushing thread java.io.NotSerializableException: org.eclipse.californium.core.CoapObserveRelation Serialization stack: - object not serializable (class: org.eclipse.californium.core.CoapObserveRelation, value: org.eclipse.californium.core.CoapObserveRelation@25d5cb65) at org.apache.spark.serializer.SerializationDebugger$.improveException(SerializationDebugger.scala:40) at org.apache.spark.serializer.JavaSerializationStream.writeObject(JavaSerializer.scala:47) at org.apache.spark.serializer.SerializationStream.writeAll(Serializer.scala:153) at org.apache.spark.storage.BlockManager.dataSerializeStream(BlockManager.scala:1189) at org.apache.spark.storage.BlockManager.dataSerialize(BlockManager.scala:1198) at org.apache.spark.storage.BlockManager.doPut(BlockManager.scala:850) at org.apache.spark.storage.BlockManager.putIterator(BlockManager.scala:637) at org.apache.spark.streaming.receiver.BlockManagerBasedBlockHandler.storeBlock(ReceivedBlockHandler.scala:77) at org.apache.spark.streaming.receiver.ReceiverSupervisorImpl.pushAndReportBlock(ReceiverSupervisorImpl.scala:141) at org.apache.spark.streaming.receiver.ReceiverSupervisorImpl.pushArrayBuffer(ReceiverSupervisorImpl.scala:112) at org.apache.spark.streaming.receiver.ReceiverSupervisorImpl$$anon$2.onPushBlock(ReceiverSupervisorImpl.scala:97) at org.apache.spark.streaming.receiver.BlockGenerator.pushBlock(BlockGenerator.scala:198) at org.apache.spark.streaming.receiver.BlockGenerator.org $apache$spark$streaming$receiver$BlockGenerator$$keepPushingBlocks(BlockGenerator.scala:171) at org.apache.spark.streaming.receiver.BlockGenerator$$anon$1.run(BlockGenerator.scala:89) can anyone have idea about this.?

Re: [IOT] [Standards] Blocking messages from unsubscribed users

by Joachim Lindborg

In the case of IoT i use it a lot devices only look at subscription requests from unsubscribe do users. And I also have component that takes care of devices blocking all messages from non subscribed Don't know if I need a xep for it or if its implementation specific for IoT I would like to be able to turn it on as default for myself receiving only subscription requests just as I have setup Skype måndag 12 oktober 2015 skrev Steffen Larsen <zooldk(a)gmail.com>: > Hi Matthew, > > Good call.
