Internet of Things (IoT) refers to physical and virtual objects that have unique identities and are connected to the internet to facilitate intelligent applications that make energy, logistics, industrial control, retail, agriculture and many other domains "smarter". Internet of Things is a new revolution of the Internet that is rapidly gathering momentum driven by the advancements in sensor networks, mobile devices, wireless communications, networking and cloud technologies. Experts forecast that by the year 2020 there will be a total of 50 billion devices/things connected to the internet.
This book is written as a textbook on Internet of Things for educational programs at colleges and universities, and also for IoT vendors and service providers who may be interested in offering a broader perspective of Internet of Things to accompany their own customer and developer training programs. The typical reader is expected to have completed a couple of courses in programming using traditional high-level languages at the college-level, and is either a senior or a beginning graduate student in one of the science, technology, engineering or mathematics (STEM) fields. Like our companion book on Cloud Computing, we have tried to write a comprehensive book that transfers knowledge through an immersive "hands on" approach, where the reader is provided the necessary guidance and knowledge to develop working code for real-world IoT applications.
Here's how big data and the Internet of Things work together: a vast network of sensors (IoT) collect a boatload of information (big data) that is then used to improve services and products in various industries, which in turn generate revenue.

Brain Computer Interface Next Generation of Human Computer InteractionSaurabh Giratkar
In the area of HCI research the main focus is on defining new ways of human interaction with computer system. With the passes of time a number of inventions have been made in this field. In initial days we used only keyboards to access our computer system (e.g. in Unix Terminal). In Second phase, after invention of mouse and other pointing devices, we started using graphical user interface using pointing devices like mouse which make the use of computer more easy and comfortable. Nowadays we are using pressure-driven mechanism, i.e. touch screen, which is common at ATMs, Mobile phones and PDAs etc. Although it is not as common in daily works but the release of tablet PCs and its popularity shows that the day is not much far when we wouldn’t be having keyboards and mouse at all.
All of these inventions have been made for balancing the requirements of society and user. E.g. Games, Multimedia Applications etc are not possible using only-Keyboard so we need mouse driven system for such applications, similarly we cannot have large keyboard on mobile so we need a touch screen system for mobiles. In addition to these traditional HCI models, there are some more advance HCI technology too for adding more flexibility and hence making the product more useful. E.g. swap card system at office doors for attendance and ATM-swap card for shopping. Speech processing systems are also there where we can access our computer system using our speech. Fig 1 shows most popular traditional HCI system.

Privacy preserving public auditing for secured cloud storagedbpublications
As the cloud computing technology develops during the last decade, outsourcing data to cloud service for storage becomes an attractive trend, which benefits in sparing efforts on heavy data maintenance and management. Nevertheless, since the outsourced cloud storage is not fully trustworthy, it raises security concerns on how to realize data deduplication in cloud while achieving integrity auditing. In this work, we study the problem of integrity auditing and secure deduplication on cloud data. Specifically, aiming at achieving both data integrity and deduplication in cloud, we propose two secure systems, namely SecCloud and SecCloud+. SecCloud introduces an auditing entity with a maintenance of a MapReduce cloud, which helps clients generate data tags before uploading as well as audit the integrity of data having been stored in cloud. Compared with previous work, the computation by user in SecCloud is greatly reduced during the file uploading and auditing phases. SecCloud+ is designed motivated by the fact that customers always want to encrypt their data before uploading, and enables integrity auditing and secure deduplication on encrypted data.

The computing continuum extends the high-performance cloud data centers with energy-efficient and low-latency devices close to the data sources located at the edge of the network. However, the heterogeneity of the computing continuum raises multiple challenges related to application and data management. These include (i) how to efficiently provision compute and storage resources across multiple control domains across the computing continuum, (ii) how to decompose and schedule an application, and (iii) where to store an application source and the related data. To support these decisions, we explore in this thesis, novel approaches for (i) resource characterization and provisioning with detailed performance, mobility, and carbon footprint analysis, (ii) application and data decomposition with increased reliability, and (iii) optimization of application storage repositories. We validate our approaches based on a selection of use case applications with complementary resource requirements across the computing continuum over a real-life evaluation testbed.
Undertaking a digital journey starts with clearly articulating the success factors for the entire digital journey, and our experience from the field has shown it to be an Achilles heel for most CXOs, across Fortune 500 organizations. Our findings were corroborated when a Mckinsey study reported that only 15% of the organizations are able to calculate the ROI of a digital initiative.
In this talk we will deliberate on demonstrated examples from multi-billion dollar businesses around proven methodologies to measure the value of a digital enterprise. The panel will share experiences as well as provide actionable advice for immediate next steps around the following:
Successful metrics for measuring the value for Digital / IoT / AI/ Machine learning engagements
How can 'Digital Traction Metrics' help with actionable insights even before the Financial Metrics have been reported
What are the best in-class organizational constructs and futuristic employee engagement methods to facilitate the digital revolution

ING CoreIntel - collect and process network logs across data centers in near ...Evention
Security is at the core of every bank activity. ING set an ambitious goal to have an insight into the overall network data activity. The purpose is to quickly recognize and neutralize unwelcomed guests such as malware, viruses and to prevent data leakage or track down misconfigured software components.
Since the inception of the CoreIntel project we knew we were going to face the challenges of capturing, storing and processing vast amount of data of a various type from all over the world. In our session we would like to share our experience in building scalable, distributed system architecture based on Kafka, Spark Streaming, Hadoop and Elasticsearch to help us achieving these goals.
Why choosing good data format matters? How to manage kafka offsets? Why dealing with Elasticsearch is a love-hate relationship for us or how we just managed to put it all these pieces together.
Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.

21. Before: How to integrate this variety of data and make it available to all products?
▪ LinkedIn grew to have dozens of data systems and data repositories.
▪ LinkedId described their point-to-point data pipelines like;
The first presentation for Kafka Meetup @ Linkedin (Bangalore) held on 2015/12/5 21
22. After
▪ Kafka was crated to server as centralized online data pipelining system:
▪ Elastically scalable
▪ Durable
▪ High-throughput
▪ Fast
22
23. Why must be concerned
▪ Over 1,300,000,000,000 messages are transported via Kafka every
day at LinkedIn
▪ 300 Terabytes of inbound and 900 Terabytes of outbound traffic
▪ 4.5 Million messages per second, on single cluster
▪ Kafka runs on around 1300 servers at LinkedIn
Newsfeed Recommendation Metrics and Monitoring23
24. A few important characteristics
Fast
◦ Kafka can handle hundreds of megabytes of reads and writes per second from a
large number of clients.
◦ Designed for real time activity streaming.
Distributed and highly scalable
◦ Kafka has a cluster-centric design offers strong durability and fault-tolerance
guarantees.
◦ Messages partitioning spread over a cluster of machines
Durable
◦ Message persisted to disk and replicated within cluster to prevent data loss.
◦ Each broker can handle terabytes of messages without performance impact
25. Kafka architecture: Broker, Topics, Producers,
and Consumers
26
Kafka Cluster is made up of multiple Kafka Brokers
33. Run Kafka Server (Broker)
Wait about 30 seconds or so for Kafka to startup.
35
34. Create Kafka Topic
• We create a topic called my-topic with a replication factor of 1 since we only have one server.
• We will use 13 partitions for my-topic, which means we could have up to 13 Kafka consumers.
36
35. Run Kafka Producer
• Notice that we specify the Kafka node which is running at localhost:9092..
• Next run start-producer-console.sh and send at least four messages
37
36. Run Kafka Consumer
Notice that we specify the Kafka node which is running at localhost:9092 like
we did before, but we also specify to read all of the messages from my-topic
from the beginning —from-beginning.
38
37. Running Kafka Producer and Consumer
• Notice that the messages are not coming in order.
• This is because we only have one consumer so it is reading the messages from all 13
partitions.
• Order is only guaranteed within a partition.

46. Disadvantages of Pure Cloud Service Model
o Unpredictable response time from cloud server to endpoints
o Unreliable cloud connections can bring down the service
o Excessive data can overburden infrastructure
o Privacy issues when sensitive customer data are stored in the cloud
o Difficulties in scaling to ever increasing number of sensors and actuators
49
47. Fog computing for IoT
• Bringing computing and analytics closer to the end-users/devices to remove unnecessary and
prohibitive communication delays (saves on transmissions costs).
• It can receive, process and react in real time to the incoming data.

50. Streaming machine-learning application to detect
anomalies in data from a heart monitor
◦ Cheaper sensors that can monitor vital signs combined with machine learning, are making it
possible for doctors to rapidly apply smart medicine to their patients’ cases.
electrocardiogram (ECG)
53
51. Building the Model with Clustering
Heartbeats activity: normal EKG pattern
we use this repeating pattern to train a model on
previous heartbeat activity and then compare
subsequent observations to this model in order to
evaluate anomalous behavior.
To build a model of typical heartbeats activity, we process an
EKG (based on a specific patient or a group of many patients),
break it into overlapping pieces that are about 1/3 sec long, and
then apply a clustering algorithm to group similar shapes.
The k-means algorithm
54
55. Detecting Anomalies
The difference between the observed and expected EKG (the green minus the red) is
the reconstruction error, or residual (shown in yellow). If the residual is high, then
there could be an anomaly.
