1. 31. Football on mobile phones : algorithms, architectures and quality of experience in streaming video

   Författare :Jiong Sun; Haibo Li; Fernando Pereira; Umeå universitet; []
   Nyckelord :Electrical engineering; Quality of Experience; Wyner-Ziv coding; Universal Multimedia Access; motion estimation; Dynamic Programming; traffic prediction; utility function; vibrotactile; Elektroteknik; elektronik och fotonik; Electronics; elektronik;

   Sammanfattning : In this thesis we study algorithms and architectures that can provide a better Quality of Experience (QoE) for streaming video systems and services. With cases and examples taken from the application scenarios of football on mobile phones, we address the fundamental problems behind streaming video services. LÄS MER

3. 32. Agile, Resilient and Cost-efficient Mobile Backhaul Networks

   Författare :Forough Yaghoubi; Lena Wosinska; Marija Furdek; Jiajia Chen; Amitava Mukherjee; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G; software defined networking; rain disturbance; technoeconomic framework; network consistency.; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The exponentially increasing traffic demand for mobile services requires innovative solutions in both access and backhaul segments of 5th generation (5G) mobile networks. Although, heterogeneous networks (HetNets) are a promising solution for the wireless access, the backhaul segment has received considerably less attention and falls short in meeting the stringent requirements of 5G in terms of capacity and availability.

4. 33. Resource Allocation under Uncertainty : Applications in Mobile Communications

   Författare :Mathias Johansson; Anders Ahlén; Mikael Sternad; Vikram Krishnamurthy; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; resource allocation; uncertainty; probability theory as logic; scheduling; multiuser diversity; Jaynes; maximum entropy; Bayesian probability theory; Signalbehandling; Signal processing; Signalbehandling; Signal Processing; signalbehandling;

   Sammanfattning : This thesis is concerned with scheduling the use of resources, or allocating resources, so as to meet future demands for the entities produced by the resources. We consider applications in mobile communications such as scheduling users' transmissions so that the amount of transmitted information is maximized, and scenarios in the manufacturing industry where the task is to distribute work among production units so as to minimize the number of missed orders.

5. 34. Agile, Resilient and Cost-efficient Mobile Backhaul Networks : Fundamentals of Network Design and Adaptation

   Författare :Forough Yaghoubi; Marija Furdek; Lena Wosinska; Dipak Ghosal; KTH; []
   Nyckelord :5G; topology design and control; software defined networking; rain disturbance; techno-economic framework; network consistency.; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The exponentially increasing traffic demand for mobile services requires innovative solutions in both access and backhaul segments of 5th generation (5G) mobile networks. Whilst substantial research efforts address the access segment, the backhaul part has received less attention and still falls short in meeting the stringent requirements of 5G in terms of capacity and availability.

7. 35. Alarm and service monitoring of large scale multi-service mobile networks

   Författare :Stefan Wallin; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pervasive Mobile Computing; Distribuerade datorsystem;

   Sammanfattning : Two of the most important challenges in network service assurance are * an overwhelming flow of low-quality alarms * to understand the structure and quality of the delivered services This thesis proposes solutions for alarm and service monitoring that addresses monitoring of large scale multi-service mobile networks. The work on alarms are based on statistical analysis of data collected from a real-world alarm flow and an associated trouble ticket database containing the network administrators expert knowledge.
