1. UWB-based wireless sensor network with medical application
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och SystemSammanfattning : This master thesis aims to develop a prototype of a wireless sensor network (WSN) using ultra wideband (UWB) radio and communication. The WSN consists of five sensor nodes and one sink which is connected to an Android smartphone. The smartphone acts as a sensor data management unit and has the ability to display sensor measurements. LÄS MER
2. An experimental verification of single-frequency networks in multi-hop ad hoc networks
Kandidat-uppsats, Mittuniversitetet/Avdelningen för informations- och kommunikationssystemSammanfattning : A multi-hop ad hoc network requires no infrastructure, like base stations or routers to function. This means that it can quickly be deployed and in movement, making it ideal for scenarios like natural disasters or battlefield communication. LÄS MER
3. Measurement Based Vehicle-to-Vehicle Multi-link Channel Modeling and Relaying Performance
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : There has been intense research in vehicular communication in order to provide reliable low-latency vehicular communication links for developing intelligent transportation system (ITS). As one of the important properties, vehicle-to-vehicle (V2V) communication is learned to be inherently non-stationary due to the high mobility of both transmitter (TX) and receiver (RX). LÄS MER
4. Cooperative Diversity and Power Consumption in Multi-hop WSN : Effects of node energy on Single Frequency Networks
Master-uppsats, Avdelningen för informations- och kommunikationssystemSammanfattning : At the present time, wireless sensor networks are becoming more and more common and energy consumption is a key factor in the deployment and maintenance of these networks. This thesis compares non-SFN multi-hop and a single frequency network (SFN) or cooperative diversity algorithms with respect to the energy consumed by the nodes. LÄS MER
5. Error Rate Performance of Multi-Hop Communication Systems Over Nakagami-m Fading Channel
Master-uppsats, Institutionen för datavetenskap, fysik och matematik, DFMSammanfattning : This work examines error rate performance of Multi-Hop communication systems, employing Single Input Single Output (SISO) transmissions over Nakagami-m fading channel. Mobile multi-hop relaying (MMR) system has been adopted in several Broadband Wireless Access Networks (BWAN) as a cost-effective means of extending the coverage and improving the capacity of these wireless networks.
