   Abstract : The objective of this thesis is to investigate the use of short-range wireless communication technology in industrial communication systems where there is a need for guaranteed timely delivery of correct information. Methods for achieving such capability are developed in the context of the physical layer, the data link layer and the application layer. READ MORE

6. 4. Multihop Wireless Networks with Advanced Antenna Systems : An Alternative for Rural Communication

   Author : Marvin Sánchez Garache; Jens Zander; Martha Steenstrup; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multihop Wirless Networks; Advanced Antenna Systems; Multiple Access Protocols; Spatial TDMA; CSMA CA; link-scheduling; power control; variable transmission rate; Telecommunication; Telekommunikation;

   Abstract : Providing access to telecommunication services in rural areas is of paramount importance for the development of any country. Since the cost is the main inhibiting factor, any technical solution for access in sparsely populated rural areas has to be reliable, efficient, and deployable at low-cost. READ MORE

7. 5. Centralized Routing for Prolonged Network Lifetime in Wireless Sensor Networks

   Author : Ewa Hansen; Mats Björkman; Mikael Nolin; Dag Nyström; Thiemo Voigt; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Wireless sensor networks; routing; energy efficiency; asymmetric communicaiton; communication; power consumption; computer networks; trådlösa sensornät; trådlös; kommunikation; energikonsumtion; Computer science; Datavetenskap; Computer Science; datavetenskap;

   Abstract : In this thesis centralized routing methods for wireless sensor networks have been studied. The aim has been to prolong network lifetime by reducing the energy consumed by sensor-node communication.Wireless sensor networks are rapidly becoming common in application areas where information from many sensors is to be collected and acted upon.
