  1. 1. Mobility and Routing in a Delay-tolerant Network of Unmanned Aerial Vehicles

    Författare :Erik Kuiper; Simin Nadjm-Tehrani; Roberto Baldoni; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mobility models; routing; ad hoc networks; delay-tolerant networks; Computer science; Datalogi;

    Sammanfattning : Technology has reached a point where it has become feasible to develop unmanned aerial vehicles (UAVs), that is aircraft without a human pilot on board. Given that future UAVs can be autonomous and cheap, applications of swarming UAVs are possible. LÄS MER

  3. 2. Challenged Networking : An Experimental Study of new Protocols and Architectures

    Författare :Erik Nordström; Per Gunningberg; Brian Levine; Uppsala universitet; []
    Nyckelord :Challenged networking; Network Architecture; Wireless Ad hoc Networks; Delay Tolerant Networks; Opportunistic Networks; Testbeds.;

    Sammanfattning : With the growth of Internet, the underlying protocols are increasingly challenged by new technologies and applications. The original Internet protocols were, however, not designed for wireless communication, mobility, long disconnection times, and varying bandwidths. LÄS MER

  4. 3. Development and Deployment of Delay Tolerant Networks: An Arctic Village Case

    Författare :Samo Grasic; Lars Wolf; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arbetsvetenskap; Human Work Science;

    Sammanfattning : In the late 1990s, NASA conducted a study of the Interplanetary Internet (IPN) architecture. In order to build and deploy IPN infrastructure, the network technology had to be able to cope with long radio signal propagation delays and frequent radio link disruptions. LÄS MER

  5. 4. Measurements in opportunistic networks

    Författare :Fredrik Bjurefors; Per Gunningberg; Christian Rohner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : Opportunistic networks are a subset of delay tolerant networks where the contacts are unscheduled. Such networks can be formed ad hoc by wireless devices, such as mobile phones and laptops. LÄS MER

  7. 5. Performance Analysis of Cognitive Radio Networks under Spectrum Sharing and Security Constraints

    Författare :Louis Sibomana; Zepernick Hans-Jürgen; Slimane Ben Slimane; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underlay cognitive radio networks; spectrum sharing constraints; physical layer security;

    Sammanfattning : The cognitive radio network (CRN) concept has been proposed as a solution to the growing demand and underutilization of the radio spectrum. To improve the radio spectrum utilization, CRN technology allows the coexistence of licensed and unlicensed systems over the same spectrum. LÄS MER
