Course Description

CSCI-759 Pervasive and Mobile Systems (slack channel: #csci759)

Mobile devices are an important component in modern computing. The advance in wireless networks and miniaturization of mobile devices has created an opportunity to perform computing everywhere, and through the use of everyday objects (augmented with computing elements). This course will cover fundamental concepts and technologies of pervasive and mobile systems. Topics include wireless networking, location-based services, sensing, context-driven adaptation, mobile security, and middleware management systems. Individual projects and a significant team-programming project are an integral part of the course. Note: Students should have networking background such as that obtained by taking CSCI-651 (Foundations of Computer Networks),  or similar courses in undergraduate level, or permission of instructor.

The goal of this course is to provide students with: (i) understanding of the concept of pervasive systems: topics include sensors, actuators, information modeling/management/reasoning, context-awareness/adaptation; (ii) fundamental understanding of mobile systems: topics include wireless networking, storage and power constraints, mobility; (iii) understanding of security and privacy implications in pervasive and mobile systems: topics include privacy-preserving techniques, homomorphic encryption and its applications; (iv) hand-on experience through developing real-world pervasive and mobile computing applications. Recommended readings before the class: JSON-RPC, Fuzzy Logic, Pi4J library, Android SDK, Context Modeling (Ontology, RDF), Routing Protocols (AODV, OLSR, DTN). This course consists of following components:

  • Paper Reading Challenge: study research papers from latest MobiCom, MobiSys, PerCom, or Ubicomp conferences; each group will present their study and prepare a report.
  • Group Project 1 - Interacting with the Physical world: SmartBlind that automatically adjusts itself based on current context and user preferences. android-app-screenshots
  • Group Project 2 - Sample Datasets for Distributed computation algorithm on a cluster of RaspberryPi: Large (313MB), Small (with sorted results, 62KB)


CSCI-652 Distributed Systems (slack channel: #csci652)

The course on Distributed Systems deals with computing components of networked environments. Examples of distributed systems include: the Internet, an intranet, a network of sensors, a personal area network around a person, etc. The distributed systems paradigm facilitates sharing of resources across the network. The challenges of such a paradigm are: heterogeneity, interoperability, concurrency, transparency, scalability, security, and many others. Furthermore, unlike traditional distributed systems, modern ones face new challenges in terms of mobility, disconnectedness, resource constraints, and battery limitations.

The course will be in two phases. During the first phase, we study traditional distributed computing concepts – distributed processes/objects, inter-process communication, remote procedure call, coordination, file systems, clocks and global states, security, concurrency, shared memory, transactions and replication. Second phase deals with systems – The Internet, P2P, mobile and pervasive systems, sensor systems and others. The course will comprise group project, exams and reading of research papers.

The course will use Calvin framework as an example of a distributed system. The project will use the Calvin framework. Please learn about the two MS thesis Mobile Devices In the Distributed IoT Platform Calvin and Dynamic Fault Tolerance and Task Scheduling in Distributed Systems. The project will be around implementing distributed algorithms using the Calvin framework. One important paper to have a read is the Kademlia DHT.

Calvin Constrained — A Framework for IoT Applications in Heterogeneous Environments. ICDCS 2017.

Creating your own Docker image by download this Dockerfile to a folder and run this command: docker build -t peiworld/csci652:latest . (Change peiworld to your own docker repo name) or you can docker pull peiworld/csci652 to get the precompiled image.

Covered hot topics include MapReduce, Docker, Apache Spark, BlockChain, homomorphic encryption.


CSCI-651 Foundation of Computer Networks (slack channel: #csci651)

This course will focus on studying the different aspects of computer networks, including various OSI layers, TCP/IP protocol, routing algorithms, wireless networking. Please refer to one of the following books for course materials.

Computer Networking: A Top-Down Approach 7th ed. J.F. Kurose and K.W. Ross or Barnes&Noble

Computer Networking: A Top-Down Approach 6th ed.  J.F. Kurose and K.W. Ross  or Barnes&Noble

Students will work with the instructor to co-develop protocols or algorithms related to computer networks or distributed systems. Students should prepare themselves by learning subversion control, in this case will be git. Please study the concept of git and different git commands: clone, checkout, commit, merge, branch, pull, push, rebase, cherrypick from this book or refer to git-scm site documentations.
