- This position paper gives better insight about the role and importance of Internet of Medical Things (IoMT) for independent living and re-learning for older adults. Sensing Technologies are the paradigm shift for transforming conventional healthcare practices into the smart, and self-assisted activities, which are envisioned for today's medical world. Internet of Things (IoT) and IoMT are the interrelated technologies for promoting independent living and re-learning practices. In this paper, re-learning is defined as the process for adults to recover useful instrumental activities of daily living skills that have been lost after an impairment.

Smart Sewage Water Management and Data Forecast

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- There is currently an ongoing digital transformation for sewage and wastewater management. By automating data collection and enabling remote monitoring, we will not only be able to save abundant human resources but also enabling predictive maintenance which is based on big data analytics. This paper presents a smart sewage water management system which is currently under development in southern Sweden. Real-time data can be collected from over 500 sensors which have already been partially deployed. Preliminary data analysis shows that we can build statistical data models for ground water, rainfall, and sewage water flows, and use those models for data forecast and anomaly detection.

On the move with TCP in current and future mobile networks

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Mobile wireless networks constitute an indispensable part of the global Internet, and with TCP the dominating transport protocol on the Internet, it is vital that TCP works equally well over these networks as over wired ones. This paper identifies the performance dependencies by analyzing the responsiveness of TCP NewReno and TCP CUBIC when subject to bandwidth variations related to movements in different directions. The presented evaluation complements previous studies on 4G mobile networks in two important ways: It primarily focuses on the behavior of the TCP congestion control in medium- to high-velocity mobility scenarios, and it not only considers the current 4G mobile networks, but also low latency configurations that move towards the overall potential delays in 5G networks. The paper suggests that while both CUBIC and NewReno give similar goodput in scenarios where the radio channel continuously degrades, CUBIC gives a significantly better goodput in scenarios where the radio channel quality continuously increases. This is due to CUBIC probing more aggressively for additional bandwidth. Important for the design of 5G networks, the obtained results also demonstrate that very low latencies are capable of equalizing the goodput performance of different congestion control algorithms. Only in low latency scenarios that combine both large fluctuations of available bandwidths and a mobility pattern in which the radio channel quality continuously increases can some performance differences be noticed.

Differences between the iterated prisoner's dilemma and the chicken game under noisy conditions
- 2002
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The prisoner's dilemma has evolved into a standard game for analyzing the success of cooperative strategies in repeated games. With the aim of investigating the behavior of strategies in some alternative games we analyzed the outcome of iterated games for both the prisoner's dilemma and the chicken game. In the chicken game, mutual defection is punished more strongly than in the prisoner's dilemma, and yields the lowest fitness. We also ran our analyses under different levels of noise. The results reveal a striking difference in the outcome between the games. Iterated chicken game needed more generations to find a winning strategy. It also favored nice, forgiving strategies able to forgive a defection from an opponent. In particular the well-known strategy tit-for-tat has a poor successrate under noisy conditions. The chicken game conditions may be relatively common in other sciences, and therefore we suggest that this game should receive more interest as a cooperative game from researchers within computer science.

Unstructured information as a socio-technical dilemma

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This chapter employs video data together with screen captures for presenting cases where the students try to match questions to search expressions, make decisions about whether they are allowed to visit a certain site, and examine how the students make decisions about relevance and credibility. Information always appears to be unstructured to the students and restructuring of information poses a socio-technical dilemma involving appreciation of an ideological and ethical nature.

State of the art and research challenges in the area of autonomous control for a reliable internet of services
- 2018
-
Ingår i: Autonomous control for a reliable internet of services. - : Springer Open. ; , s. 1-22
-
Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The explosive growth of the Internet has fundamentally changed the global society. The emergence of concepts like service-oriented architecture (SOA), Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS), Network as a Service (NaaS) and Cloud Computing in general has catalyzed the migration from the information-oriented Internet into an Internet of Services (IoS). This has opened up virtually unbounded possibilities for the creation of new and innovative services that facilitate business processes and improve the quality of life. However, this also calls for new approaches to ensuring quality and reliability of these services. The goal of this book chapter is to first analyze the state-of-the-art in the area of autonomous control for a reliable IoS and then to identify the main research challenges within it. A general background and high-level description of the current state of knowledge is presented. Then, for each of the three subareas, namely the autonomous management and real-time control, methods and tools for monitoring and service prediction, and smart pricing and competition in multi-domain systems, a brief general introduction and background are presented, and a list of key research challenges is formulated.

Lightweight session-key establishment for the internet of things
- 2018
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Internet of Things is evolving from the theory into reality. It is increasingly embedded into our daily lives to provide critical services such as pervasive healthcare and intelligent transportation systems, for which our privacy and security highly rely on the proper functioning of the products. This paper proposes a lightweight session-key establishment protocol that provides fundamental protection for the sensitive information flow in the Internet of Things. The new session-key establishment scheme utilizes the fact that time synchronization is a standard service in most of the Internet of Things products, and relies on loose time synchronization information to achieve secure and fast key agreement. Compared to traditional session-key establishment methods such as the one used by Wi-Fi, the new scheme is more lightweight and also allows a faster session establishment which can be critical for real-time services.
