2017-06-12 Workshop "Energy Efficient Electronics and Applications and SoI-training"

Published: 2017-05-19

Date: June 12-14, 2017 
Place: Ystad Saltsjöbad 

This workshop is coorganized by EIT and Associate Professor Joachim Rodrigues is in charge from LU point of view.  Other coorganizers are Andreas Burg (EPFL), Alexander Fish and Adi Teman (Bar-Ilan University). The event will take place in Ystad and attached to the workshop is also a 28 nm FD-SOI and Cadence training. 

Workshop Focus

With increasing levels of integration, embedded microelectronic systems have turned into an indispensable part of our society. While some systems such as smart phones or tablets appear very prominently and participate directly in our daily lives, others remain silently in the background to provide for functions, such as health or environmental monitoring. What almost all of these systems have in common is that they earn most of their value from mobility and require independence from the mains. Hence, they are often powered either from batteries or even through energy harvesting. As such, they must operate in a regime, where mW or even uW of power consumption are necessary to meet user expectations on battery lifetime. 

The objective of this workshop is to bring together experts, from both industry and academia, in system architecture, circuit design, and technology to discuss the challenges and the latest trends in the development of low-power and ultra-low-power embedded systems.

Title: Mobile Devices In the Distributed IoT Platform Calvin

The master project has been performed at Ericsson Research.

Abstract

Development towards a connected world where anything can talk to anything is ongoing. Calvin is a research project at Ericsson that simplifies the development of peer-to-peer applications for the Internet of Things. Calvin is created in order to let the developer of an application for the Internet of Things focus on the implementation instead of having to worry about underlying protocols, hardware access, security, application deployment, and application management. A Calvin application is defined by a dataflow graph where every node is a small reusable computational component called an Actor. The actors can move and be migrated to any connected unit during runtime which allows for complex applications to be created.

Mobile devices are computational powerful devices with a great number of sensors and has a lot of functionality through mobile device applications. The devices has traditionally only been used for configuration and control of Internet connected devices. This thesis successfully shows how mobile devices can be part of the distributed platform Calvin as any other device in the Internet of Things. The thesis proposes a general solution of how Calvin can make advantage of a mobile device at any time it is connected to the Internet. The thesis shows how mobile devices and third party applications on the device can share their capabilities in the Calvin platform with other connected devices. The thesis analyses the effect of the long term running Calvin runtime on a mobile device and shows that it is possible and feasible to use Calvin in Android without draining the device’s resources.

Title: Resource Management in Computing Systems

Special reviewer: Docent Javid Taheri, University of Karlstad 
Supervisor: Universitetslektor Christian Nyberg, EIT 
Examinator: Professor Ulf Körner, EIT 

Abstract

Resource management is an essential building block of any modern computer and communication network. In this thesis, the results of our research in the following two tracks are summarized in four papers. 

The first track includes three papers and covers modeling, prediction and control for multi-tier computing systems. In the first paper, a NARX-based multi-step-ahead response time predictor for single server queuing systems is presented which can be applied to CPU-constrained computing systems. The second paper introduces a NARX-based multi-step-ahead query response time predictor for database servers. Both mentioned predictors can predict the dynamics of response times in the whole operation range particularly in high load scenarios without changes having to be applied to the current protocols and operating systems. In the third paper, queuing theory is used to model the dynamics of a database server. Several heuristics are presented to tune the parameters of the proposed model to the measured data from the database. Furthermore, an admission controller is presented, and its parameters are tuned to control the response time of queries which are sent to the database to stay below a pre-defined reference value. 

The second track includes one paper, covering a problem formulation and optimal solution for a content replication problem in Telecom operator ’s content delivery networks (Telco-CDNs). The problem is formulated in the form of an integer programming problem trying to minimize the communication delay and cost according to several constraints such as limited content replication budget, limited storage size and limited downlink bandwidth of each regional content server. The solution of this problem is a performance bound for any distributed content replication algorithm which estimates the same problem.

2017-04-06 Tårtseminarium i E-huset 6/4 med Liesbet Van der Perre, Lise Meitner professor

Published: 2017-03-30

Titel: About setting up communication with bridges, and crossing them.
Tid: tor 6 april kl 14.06
Plats: E-huset LTH, E:1406

Välkommen till ett seminarium med professor Liesbet Van der Perre från KU Leuven i Belgien – under åren 2016-2019 verksam som Lise Meitner professor på institutionen för elektro- och informationsteknik (EIT). Van der Perre är en framstående expert inom trådlös kommunikation och samarbetar med EIT om framtidens 5G mobiltelefonsystem. Van der Perre utsågs även 2015 till hedersdoktor vid Lunds universitet.

Lise Meitner professuren är ett exempel på det arbete som ständigt pågår för att LTH skall attrahera de bästa talangerna och vara en plats för jämställdhet och mångfald. Genom denna gästprofessur bjuds en framstående forskare in till LTH för att under en tid bedriva sin forskning och fungera som förebild.

Professuren är uppkallad efter kärnfysikern Lise Meitner som var verksam när den fysikaliska vetenskapen revolutionerades. Ett långt samarbete mellan forskarna Otto Hahn och Lise Meitner ledde till upptäckten av fission (fission som i klyvningen av atomkärnor). 1944 skulle fissionsprocessen komma att belönas med Nobelpriset. Priset tilldelades endast Hahn och än idag råder delade meningar om varför Meitner inte fick dela detta pris och få samma erkännande.

Title: Evaluating Off-the-shelf Hardware for Indoor Positioning

Master Thesis presentation by Yaqin Chen.

Supervisors: Fredrik Tufvesson, Peyman Hamed Seyed Hosseini, Sigma Connectivity

Examiner: Fredrik Rusek

 

Abstract

An indoor positioning system (IPS) is a system to locate objects in indoor environments using radio waves, magnetic fields, acoustic, optical and video signals or other sensory information with help of a number of known reference positions. Nowadays, indoor positioning based services are used in a wide variety of areas and indoor positioning is getting considerable attention from both research and industry. Building indoor positioning systems using off-the-shelf hardware can considerably reduce the cost of the system implementation.

In this master thesis, three kinds of off-the-shelf hardware based on Ultra-Wideband (UWB), WiFi and Bluetooth low energy (BLE) technology respectively are exploited to build up indoor positioning systems. Evaluation and comparison of these three systems are performed through a comprehensive study of the related theory, practical experiments and brief study of off-the-shelf hardware.

Commonly used radio positioning technologies and basic indoor positioning techniques are studied as the foundation of the practical experiments. Accuracy, power consumption, cost and ease of deployment are defined as criteria to evaluate and compare the three systems. A systematic method for deploying these three positioning systems for practical experiments is presented and discussed. A trilateration positioning algorithm is implemented for these three systems to estimate positions and compare accuracy. Results from experiments for both line of sight and none line of sight scenarios are given. Results from a brief study of off-the-shelf hardware for a rough qualitative comparison of power consumption and cost of these three evaluated hardware are presented. Furthermore, obstruction experiments were performed to observe influences of the obstacles on accuracy for these three hardware. Finally, suggestions on future work are provided.

The evaluation shows that the UWB hardware performs the best accuracy for indoor positioning, in centimeter order, but it costs more than the WiFi and BLE hardware. The BLE hardware provides worst indoor positioning accuracy, around 4.5 m in average. However, it is the cheapest and most power consumption efficient among these three evaluated hardware. The WiFi hardware is a kind of a trade-off between the UWB and BLE hardware in terms of indoor positioning, giving medium level accuracy, power consumption and cost. The BLE hardware is easier to deploy compared to the UWB and WiFi hardware as BLE devices are smaller size and able to be powered by coin batteries and thus can avoid external physical connections. However, the RSS-based BLE IPS need proper propagation model to estimate distances, which adds extra workload for the deployment compared to the UWB and WiFi IPSs. Obstruction experiments show that obstacles degrade ranging performance greatly for all of these three hardware and influence on the BLE hardware is the most severe.
