  1. 16. Using Peer to Peer Over Wireless Ad Hoc Networks as an Emergency Command and Control System

    Magister-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Khadim Hussain; Choudhry Humayun Saleem; [2009]
    Nyckelord :p2p; wireless; ad hoc; networks;

    Sammanfattning : Peer-to-Peer networking technology is evolving rapidly. P2P networks overcome the limitations of client/server networks where each computer shares resources of other computer. There are different types of P2P networks depending upon their functionalities. LÄS MER

  3. 17. Cross-layer optimization protocols in Ad-hoc networks: analysis and practical implementation of transport and network layers

    L3-uppsats, KTH/Reglerteknik

    Författare :Marco Belleschi; [2008]
    Nyckelord :;

    Sammanfattning : Ad-hoc wireless networks use multi-hop transmissions to communicate, without exploiting any infrastructure. Logical links create unreliable connections between nodes: the capacity of the channel can unpredictably change due to the presence of obstructions, interferences between nodes and stochastic phenomena such as fading.

    Sammanfattning : Last decade, a lot of research has been done in wireless communication technologies. Mobile nodes such personal digital assistants (PDAs), notebooks and cell phones are nowadays used in human’s daily life. LÄS MER

  5. 19. Test Environment Design for Wireless Vehicle Communications

    Magister-uppsats, Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Alejandro Ochoa Peter Lerchbaumer; [2007]
    Nyckelord :vehicular ad hoc network; test environment; test-bed; simulator; wireless communications;

    Sammanfattning : The research in wireless communications and in-vehicle computing systems has opened up new fields of applications for transportation systems. Vehicular ad hoc networks (VANETs) emerge as a contribution to the solution of providing safer and more efficient roads and to increase passenger safety. LÄS MER

  7. 20. Simulator for Resource Allocation in Hybrid Networks

    Uppsats för yrkesexamina på grundnivå, Institutionen för datavetenskap

    Författare :Cai Li; [2005]
    Nyckelord :Datalogi; J-Sim; simulator; hybrid wireless networks; resource allocation; Datalogi;

    Sammanfattning : Much work has been done in simulating traditional cellular networks. But with the incoming of ad-hoc network technology, the next generation networks will employ hybrid network architectures using both cellular and ad-hoc networking concepts. We investigate how to create a simulator being able to simulate a hybrid wireless network. LÄS MER
