  1. 1. Design Space Exploration of Wireless Multihop Networks

    Author : Urban Bilstrup; Bertil Svensson; Högskolan i Halmstad; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless multihop networks; wireless sensor networks; Ad hoc networks; Design space; Wireless embedded networks; Packet radio networks;

    Abstract : This thesis explores the feasible design space of wireless multihop networks and identifies fundamental design parameters. In the process of exploring it is important to ignore all details and instead take a holistic view. READ MORE

  2. 2. Sensor Networks and Their Radio Environment : On Testbeds, Interference, and Broken Packets

    Author : Frederik Hermans; Per Gunningberg; Edith Ngai; Andreas Terzis; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor networks; Testbed; Mobility; Interference classification; Packet corruption; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

    Abstract : Sensor networks consist of small sensing devices that collaboratively fulfill a sensing task, such as monitoring the soil in an agricultural field or measuring vital signs in a marathon runner. To avoid cumbersome and expensive cabling, nodes in a sensor network are powered by batteries and communicate wirelessly. READ MORE
