  1. 11. Resilient Resource Allocation for Service Placement in Mobile Edge Clouds

    Författare :Peiyue Zhao; György Dán; Kin K. Leung; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Mobile edge computing makes available distributed computation and stor-age resources in close proximity to end users and allows to provide low-latencyand high-capacity services within mobile networks. Therefore, mobile edgecomputing is emerging as a promising architecture for hosting critical ser-vices with stringent latency and performance requirements, which otherwiseare challenging to be addressed in conventional cloud computing architectures.

  3. 12. Optimization heuristic solutions, how good can they be? : With empirical applications in location problems

    Författare :Xiangli Meng; Kenneth Carling; Christoph Flath; Högskolan Dalarna; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Sammanfattning : Combinatorial optimization problems, are one of the most important types of problems in operational research. Heuristic and metaheuristics algorithms are widely applied to find a good solution. LÄS MER

  4. 13. On Medium Access for Wireless Ad-hoc and Sensor Networks

    Författare :Arash Tahmasebi Toyserkani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MAC; Transmission range; Interference range; Taffic Safety; Sensor Networks; TDMA; CSMA;

    Sammanfattning : The medium access control (MAC) is a sub-layer of the data link layer, thesecond layer of the open system interconnection (OSI) model. The MAC sub-layeris responsible for organizing the access to the shared channel and it is due tothis important responsibility that the performance of networks is substantiallyinfluenced by the MAC protocol.

  5. 14. Structure Exploitation in Semidefinite Programming for Control

    Författare :Rikard Falkeborn; Anders Hansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Many control problems can be cast as semidefinite programs. However, since the size of these problems grow quite quickly, the computational time to solve them can be quite substantial. In order to reduce the computational time, many proposals of how to tailormake algorithms to various types of control problems can be found in the literature. LÄS MER

  7. 15. Distributed optimization for the optimal control of electric vehicle fleets

    Författare :Rémi Lacombe; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Platooning; Optimal control; Electric vehicles; Public transit; Distributed optimization;

    Sammanfattning : Owing to their absence of tailpipe emissions and their independence from fossil fuels, Electric Vehicles (EVs) are currently experiencing a rapid deployment in an attempt to curb global greenhouse gas emissions. EV operation represents a technical challenge, however, as new control algorithms need to be developed to address their limited driving range and their longer charging times. LÄS MER
