Organization & Evaluation • First half delivered in Semester 1 • From mid October to December • Second half delivered in Semester 2 • From mid February to April • Ongoing evaluation through exercises, class interaction and presentation • Evaluation typically executed during and immediately after the related course activities Capita Selecta - Distributed Sysems: general information
Course Activities • Tutorial style introduction to key topics • Study and discussion of research papers • Hands-on experience with technologies • Critical assessment of current practices and the state-of-the-art Capita Selecta - Distributed Sysems: general information
Module 1: Perspectives onThe Internet of Things (IoT) Danny Hughes, Wouter Joosen, Sam Michiels October-December 2011
Wireless Sensor Networks (WSN) • Tiny computers with low-power radios self organize to provide distributed sensing of the physical environment: • A key technology for the Internet of Things (IoT) • A growing marketplace: to top $38bn by 2014 • Key apps: medical, logistics, energy conservation, military • Driven by technology advances. Moore’s Law predicts: • A chip of the same size doubles in power every two years • Or, the size of a chip of the same power halves every two years (i.e. our devices are getting smaller)
Wireless Sensor Networks (WSN) • WSN Characteristics: • Large scale: 1000s of nodes over wide areas • Limited Resources: 10MHz CPU, 10K RAM, 48KB flash • Dynamism: node failure, network failure, mobility • Two key questions: • How do we implement existing protocols and middleware in such as small space? • What new abstractions, tools and support do we need to build applications for this extreme environment? • A rapidly evolving subject area, which requires knowledge of many subjects you have already studied
The WSN Module • You will revisit key topics such as: • Networking • Operating Systems • Programming Models … applied in a new and challenging IOTcontext. • Using these technologies you will learn to design networked embedded applications for various applications
Module 2: Perspectives on Cloud Computing Wouter Joosen, Eddy Truyen IBBT-DistriNet, KULeuven February-April 2012
An Architecture Paradigm Shift... • Cloud computing as the next distributed architecture • Do Scientific and enterprise computing have evolved to a common architecture … ?
An Architecture Paradigm Shift... • Cloud computing as the next distributed architecture • Do Scientific and enterprise computing have evolved to a common architecture … ? Now they want to outsource the problem And hopefully find a solution! Let’s evaluate and improve this approach…. Increased decoupling: a trivial idea, yet hard to turn into reality
