    Vitevitch, Michael S.; Ercal, Güneş; Adagarla, Bhargav (Frontiers Research Foundation, Po Box 110, Lausanne, 1015, Switzerland, 2011)
    Network science describes how entities in complex systems interact, and argues that the structure of the network influences processing. Clustering coefficient, C one measure of network structure refers to the extent to ...
  • An Intelligent Packet Loss Control Heuristic For Connectionless Real-Time Voice Communication 

    Şensoy, Murat; Yılmaz, Burcu; Yılmaz, Erdoğan (Hindawi Publishing Corporation, 410 Park Avenue, 15Th Floor, #287 Pmb, New York, Ny 10022 Usa, 2010)
    Time critical nature of the real-time communication usually makes connection-oriented protocols such as TCP useless, because retransmission of old and probably expired packets is not desired. However, connectionless protocols ...
