What is the Internet of Things

The Internet of ThingsEverything is getting connected.

The term Internet of Things was first used by Kevin Ashton in 1999.

Wireless network between objects.

The term "Internet of Things" has come to describe a number of technologies and research disciplines that enable the Internet to reach out into the real world of physical objects.

It Refers to uniquely identifiable objects (things) and their virtual representations in an Internet-like structure.

Characteristics

Event DrivenAmbient IntelligenceFlexible Structure Semantic SharingComplex Access TechnologiesInternet of Things

AI: the autonomous and intelligent entities will act in full interoperability & will be able to auto-organize themselves depending on the context, circumstances or environment.

ED is to design the scheme depending on the need

FS means that hundreds and thousands of nodes will be disable and will be set to run.

CAT means that theres several kinds of media such as vehicle stone that they need different access technologies.

SS is the machine can rend and send by themselves. No need to tell humanbeings

Middleware for IoTMiddleware for IoT provides the connection or join between the heterogeneous domain of application and heterogeneous interfaces.

Middleware for IoT is needed for several reasons.

Difficult to define and enforce a common standard among all the diverse.

Middleware is nothing but a mechanism which joins all the different components together and enables smooth communication. It is an interface that facilitates the interaction between the Internet and the Things, which may mean hardware or applications.

SOA Based Architecture for IoT MiddlewareIt is the part of middleware application which contain Service Composition,

Service Management,

Object Abstraction.

Service Composition

A service composition is an aggregate of services collectively composed to automate a particular task or business process.

Service ManagementHere three services are discussed. Object dynamic discovery, Status Monitoring and Service Configuring.

Object Abstraction

It is capable of connecting the different devices. It includes two sub layer they are interface and the communication layer.

Interface layer is used to managing the all incoming and out coming messaging operations. Communication layer is translating into set of device specific commands

IOT PHASESThis can be divided into several phases they are (i) Collection phase (ii)Transmission phase (iii) Process, management and utilization phase each phases has different functions, protocols and interacting or communicatingtechnologies.

Collection PhaseThis phase is used for collecting the physical objects which are presented in the physical environment. It gives the procedures for sensing the physical environment and gathering real time physical data or objects such as RFID and sensors which provides identification of physical objects and physical parameters also. IEEE802.15 and Bluetooth are used for data collecting in the physical environment.

Transmission PhaseIt contains several mechanisms to produce the collected data to different applications and servers.Wired Communication --- Ethernet IEEE 802.3 from 10mbps to 1000GBPS over twisted, coppers, coaxial cables.Wireless Communication---Wi-Fi family which operates in different frequency bands.

Processing, managing and utilization phaseIt combines with processing and analyzing for flows of information and forwarding data to application and services and giving feedback to the final control applications.

It should hide the hardware, software, technologies and communications protocols in heterogeneity platform.

APPLICATIONS OF IOT

Telecommunication IndustryMerging of telecommunication technologies and create new services in the IoT. Some of the examples are GSM, Bluetooth, WLAN, WFC, GPS, Multi hop networks and various sensor networks with Sim card technology. IoT in the telecommunication industry improves the robustness of communication channels and networks.

Medical and Healthcare IndustryMost of the IoT applications are included in the medical sector. RFID sensor has ability to monitoring the medical parameters and drug delivery.Advantage of this technologies are prevent and monitoring the disease and diagnosing and taking actions for preventing the diseases.

Logistics and Supply Chain ManagementExchanging the RFID data can use the logistics and supply chain managementAerospace and Aviation IndustryImproving safety and security of product elements by identifying the process and elements.

FUTURE DIRECTIONS IN THE IOTSocial Networks Contribution

Context Aware Computing

Social Networks ContributionThere are three main stages involved in the social networks into the IoT. First step exploits human with network relationships to share the resources. Finally objects can communicate by different protocols and communication paradigm. For example sense share is used to gathering the data by smart things. It exploits the data sharing.

Context Aware ComputingContext awareness may manage the huge amount of data or Big Data. It is used to characterizing the situation of an entity.

It is also used to implementation of services by service discovery mechanisms.

CONCLUSIONIn the proposed solution, we will provide the security to the IoT data and to avoid the security threats in the IoT network objects.

In this survey we discussed and learnt about IoT vision and services, technologies. Finally we have great knowledge about the IoT services and communications among the network objects.
