  1. 1. Architectures for Service Differentiation in Overloaded Internet Servers

    Författare :Thiemo Voigt; Peter Druschel; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Internet; Web Servers; Operating Systems; Service Differentiation; Admission Control; Information technology; Informationsteknik; Computer Systems; Datorteknik;

    Sammanfattning : Web servers become overloaded when one or several server resources such as network interface, CPU and disk become overutilized. Server overload leads to low server throughput and long response times experienced by the clients. Traditional server design includes only marginal or no support for overload protection. LÄS MER

  4. 4. Detailed simulation of heterogeneous wireless sensor networks

    Författare :Joakim Eriksson; Thiemo Voigt; Per Gunningberg; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : Wireless sensor networks consist of many small nodes. Each node has a small microprocessor, a radio chip, some sensors, and is usually battery powered which limits network lifetime. Applications of wireless sensor networks range from environmental monitoring and health-care to industrial automation and military surveillance. LÄS MER

  5. 5. Towards adaptive sensor networks

    Författare :Niclas Finne; Thiemo Voigt; Per Gunningberg; Uppsala universitet; []
