Tutorial I - Distributed Beam and  Nullforming for Distributed MIMO
Date of Tutorial: August 25, 2013

Speaker:
Prof. Soura Dasgupta
The University of Iowa, USA

Multi-antenna, or MIMO, technology has revolutionized wireless communication in terms of both power and spectral efficiency, and is now a part of commercial wireless standards (e.g., WiFi and cellular). MIMO techniques today, however, are fundamentally constrained by form factor and carrier wavelength, both of which determine the number of antennas that can be accommodated on a transceiver.

In recent years proposals have been made for distributed MIMO where groups of transceivers self-organize into virtual arrays that are indistinguishable in their functionality from a centralized antenna array and scales to an arbitrary number of nodes. Such distributed MIMO (DMIMO) concepts have long been analyzed by theorists and dismissed by practitioners because of fundamental synchronization bottlenecks. This is so as unlike centralized antennas, distributed MIMO involves nodes that each operates on its own clock. The frequency and phase of these oscillators undergo drift modeled by Brownian motion. Even if they start in complete synchrony, they become virtually incoherent within fractions of milliseconds. Nonetheless there has been exciting recent progress some of which the proposer and his colleagues, R. Mudumbai from the University of Iowa, D. R. Brown from Worcester Polytechnic Institute, and U. Madhow from the University California at Santa Barbara, have pioneered.

The proposed tutorial will focus on synchronization issues involving two basic building blocks of DMIMO: distributed beamforming and distributed nullforming. In the former N-nodes collaborate to achieve a coherent beam whose power is N2-fold (as opposed to N-fold) that due to a solitary node. Incoherence only results in an N-fold increase. In nullforming, nodes achieve a null at a prescribed location. It assists in achieving spatial-multiplexing and also secure communication. The key ingredient is scalable feedback by a cooperating receiver.

The specific topics to be covered are as follows.

1. Introduction

a. DMIMO

b. Distributed Beam and Nullforming

2. How do oscillators behave?

3. How to synchronize?

4. Scalable feedback for Distributed Beamforming

5. Scalable feedback for Distributed Nullforming

6. Properties

7. Where do we go from here?


 

 Tutorial 2 - Future Internet Architecture and Services: e-Healthcare monitoring applications

Date of Tutorial: August 22, 2013

Speaker:
Dr. Dhananjay Singh

We are living in a world which human systems, natural systems and physical objects with each other generating huge amounts of data that can be captured and accessed by today’s technologies. However, there is much more stuff on the Internet than people on the Internet. The idea is as simple as its applications are difficult. If all the things, used by us in daily life, can be identified devices, there would be no more wastage of product and no more stealing since all the things can be tracked down and we get to know how it is used and we can enhance the quality of life. This tutorial focus on sensor oriented internet based e-healthcare monitoringapplications system in which doctor can access patient vital information and status any time through PDA device or smart phone. The idea is simple but its application is difficult. This tutorial talk will provide a new metric of success for global connectivity of healthcare system for Smart Hospital and Smart Home area networks. Talk covers the fundamental of e-Healthcare system, IPv6 connectivity over small embedded device, IETF 6lowpan technology, wireless ad-hoc and sensor networks etc. The tutorial will alsofocus on a possible Architecture of Future Internet to support internet oriented services and further extension of this technology for communication between Machines to Machine, User to User, User to Machine makes successful step for future internet.

Date of Tutorial: August 24, 2013

Speaker:
Dr. Kumar Padmanabh
Robert Bosch, Bangalore, India

Sensors and actuators are the fundamental constituents of cyber physical systems (CPS). Every sensors are ought to produce data. The pervasiveness of sensors, the requirement of collaborative processing of data, the historical importance of data and ever increasing different forms of user applications are not only making the data management more complex, they are also bringing more challenges in the scalability of systems. There are three stages of complexities associated with the scalability of a CPS: firstly in the physical infrastructure of the data acquisition system, secondly in the communication mechanism and thirdly in the server and user applications. In all these three stages, the diversity, interoperability and capacity limitations of individual components play an important role in establishing the overall scalability limits a cyber-physical system. In this tutorial the significance and relevance of the technologies developed for cloud computing and big data for the scalability of future cyber physical system will be highlighted. It is will explained how cloud computing, Big Data Analytics and associated technologies would help the system to scale.
