  1. 1. UWB-based wireless sensor network with medical application

    University essay from Uppsala universitet/Signaler och System

    Author : Joakim Lindström; [2018]
    Keywords : ;

    Abstract : 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. READ MORE

  3. 2. An experimental verification of single-frequency networks in multi-hop ad hoc networks

    University essay from Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

    Author : Rafid Mahdi; Pontus Tobiasson; [2016]
    Keywords : SFN; DSFN; OFDM; 802.11a; Wireless multi-hop ad hoc network.;

    Abstract : 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. READ MORE

  4. 3. Measurement Based Vehicle-to-Vehicle Multi-link Channel Modeling and Relaying Performance

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Xi Chen; [2015]
    Keywords : V2V; wireless; channel model; multilink; relaying; sum of sinusoids; correlated Gaussian; maximum likelihood estimation; Technology and Engineering;

    Abstract : 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). READ MORE

  5. 4. Cooperative Diversity and Power Consumption in Multi-hop WSN : Effects of node energy on Single Frequency Networks

    University essay from Avdelningen för informations- och kommunikationssystem

    Author : ANWAAR UL HAQ; HAROON MALIK; [2014]
    Keywords : Macro diversity; Multi-hop; Single Frequency network; Reachability; Decline; Outage;

    Abstract : 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. READ MORE

  6. 5. Error Rate Performance of Multi-Hop Communication Systems Over Nakagami-m Fading Channel

    University essay from Institutionen för datavetenskap, fysik och matematik, DFM

    Author : Hassan Sajjad; Muhammad Jamil; [2012]
    Keywords : Signal Processing; Fading Channel; Multi-hop;

    Abstract : 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.
