Introducing the IPSO Alliance – IP Smart Objects

The IPSO Smart Object: Currently, OMA LWM2M is a common device management mechanism provided by Open Mobile Alliance. The object model in OMA LWM2M is reused to define application level IPSO Smart Object. An IPSO Smart Object is a collection of reusable resources that has a well-known object ID and represents a particular type ofContinue reading “Introducing the IPSO Alliance – IP Smart Objects”

OneM2M Overview – Part 1

oneM2M is a global standardization to develop a horizontal platform for the exchange and sharing of data among M2M and IOT applications. OneM2M provides a framework for interworking with different technologies and enabling re-use of what is already available as much as possibile such as LwM2M for device management, binding with various existent protocol.  Continue reading “OneM2M Overview – Part 1”

Overview Semantic in Internet of Thing

Interoperability among the “Thing” on the IoT is the most fundamental requirements to support object address, tracking, and discovery as well as exchange, storage, and representation information. In order to these goals, the suite of technologies developed in the Semantic Web such as ontologies, semantic annotation, Linked Data and semantic web service is used asContinue reading “Overview Semantic in Internet of Thing”

Overview OMA Lightweight M2M Protocol

1. Introduction Light weight machine to machine (LWM2M) is an application communication protocol based on client-server architecture. This protocol was first introduced by OMA. The OMA lightweight M2M facilitate device management and service enablement for LWM2M Devices. Four interfaces are designed for these purposes as shown below: Bootstrap: is used to prepare vital information onContinue reading “Overview OMA Lightweight M2M Protocol”

Overview Sensor Web Enablement

Sensor Web Enablement (SWE) is an open standard framework of Open Geospatial Consortium (OGC) for exploiting Web-connected sensor and all-types of sensor system. The models, encodings, and services of the SWE architecture enable implementation of interoperable and scalable service-oriented networks of heterogeneous sensor systems and client applications. The goal of SWE is to enable allContinue reading “Overview Sensor Web Enablement”

Overview MQTT Protocol

Each Subscription within a session has a different topic filter. Topic Name: The label attached to an Application Message which is matched against the SubscriptionsContinue reading “Overview MQTT Protocol”

Survey Internet of Thing Protocol

Following some resources from internet, Internet of thing is identified to be “a scenario in which objects, animals or people are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.”. But in my view, it is simple the way we connect everything around us withContinue reading “Survey Internet of Thing Protocol”
