2. 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

4. 2. Energy Constrained Wireless Sensor Networks : Communication Principles and Sensing Aspects

   Author : Erik Björnemo; Anders Ahlén; Mikael Sternad; Erik Larsson; Uppsala universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless sensor network; communication under processing cost; wireless channels; fading; probability theory as logic; uncertainty; measurement capacity; Signal processing; Signalbehandling;

   Abstract : Wireless sensor networks are attractive largely because they need no wired infrastructure. But precisely this feature makes them energy constrained, and the consequences of this hard energy constraint are the overall topic of this thesis. READ MORE

5. 3. Wireless Interface Technologies for Sensor Networks

   Author : Magnus Jobs; Anders Rydberg; Andrei Sazonov; Uppsala universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless Sensor Networks; Body Area Networks; Jet Turbine; Electrically Small Antennas; Antenna Theory; WISENET; Wisejet; Engineering Science with specialization in Microwave Technology; Teknisk fysik med inriktning mot mikrovågsteknik;

   Abstract : The main focus of the work presented in this thesis concerns the development and improvement of Wireless Sensor Networks (WSNs) as well as Wireless Body Area Networks (WBANs). WSN consist of interlinked, wireless devices (nodes) capable of relaying data wirelessly between the nodes. READ MORE

6. 4. Using Existing Infrastructure as Support for Wireless Sensor Networks
