  1. 1. Improving Low-Power Wireless Protocols with Timing-Accurate Simulation

    Författare :Fredrik Österlind; Thiemo Voigt; Adam Dunkels; Per Gunningberg; Tarek F. Abdelzaher; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Low-Power Wireless Protocols; Wireless Sensor Networks; Contiki; Cooja; Simulation; Datavetenskap med inriktning mot datorkommunikation; Computer Science with specialization in Computer Communication;

    Sammanfattning : Low-power wireless technology enables numerous applications in areas from environmental monitoring and smart cities, to healthcare and recycling. But resource-constraints and the distributed nature of applications make low-power wireless networks difficult to develop and understand, resulting in increased development time, poor performance, software bugs, or even network failures.
