All market and technology studies forecast an explosive growth in the number of “things” which will be connected to the Internet. The resulting network is what is commonly known as the “Internet of Things” (IoT). The IoT poses completely new challenges when compared to the traditional Internet which cannot be faced if the involved objects are just traditional “smart” objects. In fact, the extremely high complexity (huge number of nodes, extreme heterogeneity of their resources and capabilities, uncertainty on their trustworthiness, etc.) of the IoT environment cannot be faced by even very smart objects singularly. Social behavior is the answer found by several creatures to face the complexity of the surrounding environment. Accordingly, recently the concept of Social Internet of Things (SIoT) has been introduced and is the subject of a rapidly increasing research effort. In this tutorial we will motivate the SIoT introduction, we will provide the basic relevant concepts, will survey the existing literature, and will describe a specific solution in details providing some exemplary applications.

Apache Storm is a popular low latency distributed stream processing framework. Apache Storm is used everywhere at Yahoo and at many other companies from automatically tagging every image uploaded to Flickr and analyzing trending search queries to monitoring production servers looking for problems. This hands on tutorial is divided into two parts. The first part covers the basics of Storm, its architecture, and walks you through writing a simple application (not just word count). The second part looks more at how to modify Storm and will walk you through adding in a new feature to storm.

Session details:

Part 1: An introduction to Apache Storm (2 hours)

  • Why Stream Processing is Important
  • Apache Storm's Architecture
  • Trident (Micro Batch Processing on Storm)
  • DRPC
  • Hands On Example

Part 2: Modifying Apache Storm (1 hour)

  • Layout of source code
  • Walk through of adding a new feature to Storm

Prerequisites: none

Duration: ~180 min

Over the last few years, more and more Cloud Computing offerings have emerged ranging from compute, data storage, and middleware services over platform environments up to ready-to-use applications. Choosing the best offering for a particular use case, is a complex task which involves comparison and trade-off analysis of functional and non-functional service properties; for non-functional quality of service (QoS) properties, this is typically done via benchmarking. Today, a plethora of benchmarking solutions exist for different layers in the cloud stack (IaaS, PaaS, SaaS) which typically address a single QoS dimension – a holistic cloud benchmark even for a single layer in the cloud stack is still missing. In this tutorial, we will give an overview of existing cloud benchmarking solutions and point-out ways in which these different benchmarks could be used in concert to actually compare clouds as a whole (i.e., for instance Amazon cloud vs. Google cloud) instead of analyzing isolated QoS dimensions of single cloud services.

Session details:

Topics (1 hour + 1 hour)

  • Requirements and key properties of benchmarks and metrics in general
  • Performance benchmarks for cloud storage – from TPC to YCSB and recent developments
  • Benchmarking approaches for advanced QoS dimensions (e.g., consistency, availability, elasticity)
  • Benchmarking approaches for middleware services and compute clouds
  • The future of benchmarking: New research directions, holistic cloud benchmarks, and cloud-specific benchmarks

Prerequisites: none

Duration: ~120 min

The rise of the Social Internet, in the past decade, stimulated the invention of human-centered technologies that study and serve humans as individuals and in groups. For instance, social networking services provide ways for individuals to connect and interact with their friends. Also, personalized recommender systems leverage the collaborative social intelligence of all users' opinions to recommend: books, news, movies, or products in general. These social technologies have been enhancing the quality of Internet services and enriching the end-user experience. Furthermore, the Mobile Internet allows hundreds of millions of users to frequently use their mobile devices to access their healthcare information and bank accounts, interact with friends, buy stuff online, search interesting places to visit on-the-go, ask for driving directions, and more. In consequence, everything we do on the MobiSocial Internet leaves breadcrumbs of digital traces that, when managed and analyzed well, could definitely be leveraged to improve life. Services that leverage Mobile and/or Social data have become killer applications in the cloud. Nonetheless, a major challenge that Cloud Service providers face is how to manage (store, index, query) MobiSocial data hosted in the cloud. Unfortunately, classic data management systems are not well adapted to handle data-intensive MobiSocial applications. The tutorial surveys state-of-the-art MobiSocial data management systems and research prototypes from the following perspectives: (1) Geo-tagged Microblog search, location-aware and mobile social news feed queries, and GeoSocial Graph search, (2) Mobile Recommendation Services, and (3) Geo-Crowdsourcing. We finally highlight the risks and threats (e.g., privacy) that result from combining mobility and social networking. We conclude the tutorial by summarizing and presenting open research directions.

Session Details (Half Day):

Part 1 (1 hour)

In the first part, we start by giving a quick overview of social networking services (e.g., Facebook, Twitter), their evolution, and how they impact the society. Similarly, we explain through examples and case studies how the widespread of mobile devices changes the computing paradigm in a way that impacted our daily life. We then illustrate how the marriage of both social networking and mobility technologies has led to the rise of location-based social networking systems. We give a brief history of several attempts to combine social networking and mobility. Therefore, we explain the richness of data generated by merging both social networking and mobility: (1) Social Networking data: represents the friendship between different users (usually represented by a social graph) as well as all sorts of social interactions between users. (2) Spatial/Spatio-temporal data: represents the users geo-locations, venues (e.g., restaurant, gym, and shopping mall) geo-locations and information about users visiting different places at different times. (3) Users Opinions data: represents how much a user likes the places she visits by expressing (e.g., Alice visited restaurant A and gave it a rating of five over five). We then illustrate how different mixes of this data trilogy has been leveraged to explore new trends and by developers to build novel mobile applications.

Part 2 (2 hours)

In the second part of the tutorial, we present the state-of-the-art research in managing MobiSocial data, from the following perspectives: (1) GeoSocial Search and Query Processing: That incorporates both the geo-location and the social awareness in answering queries. We then present several indexing and query processing algorithms that efficiently access geo-tagged social media (e.g., tweets, news feed, social graph entities). (2) Mobile Recommendation Services: We present recent studies which show that geo-location matters in recommender systems, and we manifest several techniques to incorporate the spatial/spatio-temporal information and users opinions data side by side in traditional recommender systems. We also highlight the research works that leverage GeoSocial data points and trajectories for travel and itinerary recommendations. (3) Location-aware Crowdsourcing: We give an overview of the Volunteered Geographic Information (VGI) area and we survey the recent papers that address the Crowdsourcing topic from a geographic perspective. For all aforementioned topics, we present results from recent research work, case studies from hot mobile applications, and the anatomy of built systems. Then, we highlight the main risks that result from combining social networking and mobility (e.g., privacy). Finally, we introduce possible research directions to the audience and we also manifest several resources, e.g., data, software tools, that assist the audience in starting their own research in social networking and mobility.
