IoTivity Services in v0.9.2

Resource Encapsulation

In IoTivity v0.9.2, IoTivity Services provide the common set of functionalities to application development by additional “Resource Encapsulation Layer”.

Resource Encapsulation is an abstract layer which consists of common resource function modules. It provides functionalities for both the client and server side to ease the work of developers. For Client side it provides Cache and Resource Broker functionalities (monitoring the presence of resource in the network). For server side it provides the simple and direct way to create the resource and to set the properties and attributes. For handling the request from client it provides flexibility to developer either auto control of request by the layer itself or developer control the request in the application. Resource Container module of Resource Encapsulation layer provides integration of non-OIC devices into OIC devices.

Resource Encapsulation Layer consists of Resource Broker/Cache/Container and Server Builder.

Resource Broker provides the reachability information for the resource of interest, and presence checking for remote resources even if the remote resource server does not notify its presence.

Resource Cache guarantee the delivery of the selected resource data. It provides the Data-centric APIs to developers such as send/recv message, getter/setter and data cache.

Resource Container/Builder manages the lifecycle of resource server (Bundle).

If you want to know the necessary development environment and guide about Resource Encapsulation to work with each of the services, see Resource Encapsulation Programmer's Guide_v0.9.2

Services in IoTivity v0.9.2

Note : In v0.9.2, IoTivity provides the same services as v0.9.1 Release except supporting Tizen Platform. Those services are temporally unavailable for Tizen platform in IoTivity v0.9.2

IoTivity Services are designed to provide easy, scalable access to applications and resources and are fully managed by themselves.

There are four IoTivity Services, each with its own unique functionality: Protocol Plugin Manager, Soft Sensor Manager, Things Manager, and Notification Manager as same in v0.9.1

If you want to know the necessary development environment and setup information to work with each of the services, see IoTivity Services: Getting Started for Linux_v0.9.1, and Android_v0.9.1.

Protocol Plugin Manager

Protocol Plugin Manager makes IoTivity applications communicate with non-IoTivity devices by plugging protocol converters.
It provides several reference protocol plugins and plugin manager APIs to start/stop plugins.

For more details, see Programmer's Guide: Protocol Plugin Manager for Linux_v0.9.1,and Android_v0.9.1.

Soft Sensor Manager

Soft Sensor Manager provides physical and virtual sensor data on IoTivity in a robust manner useful for application developers. It also provides a deployment and execution environment on IoTivity for higher level virtual sensors. Soft Sensor has two main components:

  1. Soft Sensor Manager: A service component that 1) collects physical sensor data, 2) manipulates the collected sensing data by aggregating and fusing it based on its own composition algorithms, and 3) provides the data to applications.
  2. Soft Sensor (Logical Sensor, Virtual Sensor): A software component that detects specific events or changes in a given context by applying its predefined process model with required data.

For more details, see Programmer's Guide: Soft Sensor Manager for Linux_v0.9.1, and Android_v0.9.1.

Things Manager

Things Manager creates Groups, finds appropriate member things in the network, manages member presence, and makes group action easy. It benefits 3rd party application developers in three ways:

  1. Application can easily collect things for a specific service by the service characteristics, not by each thing's identification.
  2. Application does not require handling, tracing, or monitoring many things.
  3. Application does not require managing to send control messages to several things. Also, configuration and diagnostics of multiple things can be supported by this service.

For more details, see Programmer's Guide: Things Manager for Linux, Tizen and Android.

Notification Manager

Notification Manager provides resource hosting function. The resource hosting is a feature which stores only resource data with new address:port information. The goal of this feature is to off-load the request handling works from the resource server where original resource is located.

For more details, see Programmer's Guide: Notification Manager for Linux_v0.9.1.
