    Context: Quality of Service (QoS) is a major issue in various web service related activities. Quality models have been proposed as the engineering artefact to provide a common framework of understanding for QoS, by defining ...
  • Improving reliability of JXTA-overlay P2P platform: a comparison study for two fuzzy-based systems 

    Liu, Yi; Sakamoto, Shinji; Matsuo, Keita; Ikeda, Makoto; Barolli, Leonard; Xhafa Xhafa, Fatos (2015)
    Article
    Open Access
    In P2P systems, each peer has to obtain information of other peers and propagate the information to other peers through neighboring peers. Thus, it is important for each peer to have some number of neighbor peers. Moreover, ...
  • Analysis of mesh router placement in wireless mesh networks using Friedman test considering different meta-heuristics 

    Oda, Tetsuya; Liu, Yi; Sakamoto, Shinji; Elmazi, Donald; Barolli, Leonard; Xhafa Xhafa, Fatos (2015)
    Article
    Open Access
    In this paper, we deal with connectivity and coverage problem in wireless mesh networks (WMNs). We used Friedman test to compare genetic algorithm (GA), tabu search (TS), hill climbing (HC) and simulated annealing (SA). ...
