overview

At a first glance this can seem hard to grasp with so many extensions but it is really simple.

We need to access and control nodes and if nodes are behind a complex technology we need to find them behind a concentrator and then be able to put a device in use we need the provisioning.


Base Specifications

The core is 4 xeps that together describes more or less any sensor actuator network.

 Provides the underlying architecture, basic operations and 
 data structures for sensor data communication over XMPP networks. 
 It includes a hardware abstraction model, removing any technical 
 detail implemented in underlying technologies. 
 This XEP is used by all other sensor network XEPs.
 Defines how to control actuators and other devices in
 sensor networks.
 Defines how to handle architectures containing concentrators 
 or servers handling multiple sensors.
 This specification. Defines how provisioning, the management of
 access privileges, etc., can be efficiently and easily 
 implemented.


Enhancing Specifications

To

  • xep-0000-IoT-Discovery
 Defines the peculiars of sensor discovery in sensor networks. 
 Apart from discovering sensors by JID, it also defines how to 
 discover sensors based on location, etc.
  • xep-0000-IoT-Events
 Defines how sensors send events, how event subscription, 
 hysteresis levels, etc., are configured.


  • xep-0000-IoT-Multicast
 Defines how sensor data can be multicast in efficient ways.
  • xep-0000-IoT-PubSub
 Defines how efficient publication of sensor data can be made 
 in sensor networks.
  • xep-0000-IoT-BatteryPoweredSensors
 Defines how to handle the peculiars related to battery powered
 devices, and other devices intermittently available on the network.

Interoperability Specification

In all networks that combines information from different systems over business and technology borders the crucial thing is to get interoperability. And there is no other way to do this than creating specifications that adds the "common good practices" to make things speak the same language. The interoperability spec will be a moving target with constant elaboration to enable true interoperability between systems

  • xep-0000-IoT-Interoperability
 Defines guidelines for how to achieve interoperability in 
 sensor networks, publishing interoperability interfaces for 
 different types of devices.

Supporting Specifications

  • XEP-0000-ColorParameter
 Defines extensions for how color parameters can be handled, based on Data Forms [1]
  • XEP-0000-DynamicForms
 Defines extensions for how dynamic forms can be created, based on Data Forms [2], 
 Data Forms Validation [3], 
 Publishing Stream Initiation Requests [4] 
 and Data Forms Layout [5].
 Defines how to EXI can be used in XMPP to achieve efficient 
 compression of data. Albeit not a sensor network specific XEP, 
 this XEP should be considered in all sensor network 
 implementations where memory and packet size is an issue.
