Internet of things (IoT)- Introduction, Utilities, Applications
- 1. IoT Internet of Things By: Tarika Verma
- 2. What is IoT? Platform where every day devices become smarter every day processing becomes intelligent every day communication becomes informative It is the stringent connectedness between digital and physical world
- 3. IoT Functional Blocks 1. Device: Provide sensing, actuation, control, and monitoring activities exchange data with other connected devices and application collect data from other devices and process the data either locally send the data to centralized servers or cloud based applications back-ends for processing the data
- 4. IoT Functional Blocks 2. Communication: performs the communication between devices and remote servers 3. Services: serves various types of functions such as services for device modeling, device control, data publishing, data analytics, and device discovery. 4. Management: to seek the underlying governance of IoT system. 5. Security: secures the IoT system by providing functions such as, authentication, authorization, privacy, message integrity, content integrity, and data security. 6. Application: acts as an interface that provides necessary modules to control, and monitor the IoT system. Applications allow users to visualize, and analyze the system
- 5. Utilities of IoT 1. Dynamic and self adapting 2. Self-configuring 3. Interoperable communication protocols 4. Unique identity 5. Integrated into information network 6. Context-awareness – The decision that sensor nodes take are context aware 7. Intelligent decision making capability - multiple sensor nodes collaborate and collectively take the final decision.
- 7. Domain specific Applications Wireless Sensor Network Wireless Sensor Network (WSN) is one of the key parts of IoT system. It consists of a finite number of sensor nodes mastered by a special purpose node by employing multi layered protocols organization Primarily energy efficiency, scalability, reliability, and robustness etc. parameters are sought when designing a WSN powered system.
- 8. Domain specific Applications AquaCulture An IoT based aquaculture while providing real-time information system called ‘‘E-Nose” has been developed to pursue the information of water quality via mobile internet and WSN to the users. The system performs forecasting of the change of the trend of water quality based collected data
- 9. Domain specific Applications Distributed sensor network Emergent Distributed Bio-Organization (EDBO) model is conceived to harness emergent phenomena in Artificial Distributed Systems (ADS) EDBO nodes are represented by agents – ‘‘BioBots” which use two- way relationships to form an overlay network. Each BioBot is capable to handle a limited number of relationships to other BioBots in an autonomous environment. It facilitates the propagation of queries through the network in an autonomous manner where its behavior is based on several bio- inspired heuristic mechanisms that helps to participate in decision making. Users can invoke their requests upon the EDBO which is then processed by collective decisions made by the BioBot
- 10. Domain specific Applications Smart Society Road condition monitoring Traffic management Smart city – in Europe Smart waste management Accidental Emergency Management System Home entertainment – Real Time multimedia; DSL and IP-TV together A novel multimedia transmission protocol over UDP Arduino based hardware platform used
- 11. Domain specific Applications IoT as a Service IoT Platform as a Service (IoT-PaaS) framework. Collected sensor data is transmitted to remote IoT cloud platforms through a gateway which is a layer of various network protocols. Retail billing and related financial processes can easily be metered with IoT PaaS by consisting a nexus of application context management which is governed by allowing data flow, monitored by event processing, data services, and tenant management
- 12. IaaS (Infrastructure as a Service) — a remote data center with resources such as data storage capacity, processing power and networking. PaaS (Platform as a Service) — a development platform with tools and components for creating, testing and launching applications. SaaS (Software as a Service) — ready-made software tailored to a variety of business needs.
- 13. Domain specific Applications Location aware service The Mobility First Future Internet Architecture (MFFIA) is an ideal platform for realizing pervasive computing (location awareness) in IoT. Particularly when it is necessary to build proper blocks of applications in terms of identity based routing, overloaded identities, content caching, and in network compute plane
- 14. Domain specific Applications Fog Computing It refers to extending cloud computing to the edge of an enterprise's network. Also known as Edge Computing or fogging, It facilitates the operation of compute, storage, and networking services between end devices and cloud computing data centers. While edge computing is typically referred to the location where services are instantiated, fog computing implies distribution of the communication, computation, and storage resources and services on or close to devices and systems in the control of end-users
- 15. Domain specific Applications Big Data using Data Filtering Combines ‘‘Hadoop” along with multiple other databases to create a distributed file repository to store and efficiently manage various types of data collected by sensors Authors propose an architecture that aggregates data filtering, transforming, and integration approach together. They present a warehouse-based data model for specifying the data needed at particular points of granularity and frequency that drive data storage and representation which is aligned with the defined Semantic Sensor Network (SSN) Ontology.
- 16. Security Issue Object security End-to-End security Cyber-physical-social security Hierarchical security Multimedia traffic security Light weight security
- 17. “The IoT has added a new potential into internet by enabling communications between objects and human, making a smarter and intelligent planet.” “IoT has led the vision of ‘‘anytime, anywhere, anyway, anything” communications practically in true sense.”
