  1. 41. Refinement of an emulator for the physical layer of the wireless communication of sensor networks

    University essay from Signaler och System

    Author : Emil Eriksson; [2014]
    Keywords : WSN; emulation;

    Abstract : Wireless sensor networks have applications in many different fields and environments, each with their own set of challenges to be overcome. If we can measure and compensate for the properties of the wireless environment at an early stage of the deployment, we will be able to have the sensor network operational in a smaller time frame.

  2. 42. 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

  3. 43. Performance evaluation of interleaving techniques for IEEE 802.15.4 transmissions

    University essay from Mittuniversitetet/Avdelningen för informations- och kommunikationssystem

    Author : Jiahuan Lei; Qingbi Liao; [2014]
    Keywords : interleaving; Matlab; Reed-Solomon; TinyOS; WSN; FEC; MicaZ;

    Abstract : In the wireless sensor network, the WLAN interference, multi-path fading andattenuation are the main reason for packets’ corruption. Forward errorcorrection is one of the methods for error mitigation. Many coding methods aredesigned to improve the reliability of wireless channel. READ MORE

  4. 44. VHF/UHF Uplink Solutions for Remote Wireless Sensor Networks

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Alp Sayin; [2013]
    Keywords : ;

    Abstract : The purpose of this thesis was to compare alternative wireless links for transfer of data from sink motes of remote wireless sensor networks to a central repository. A few different protocol stacks to be implemented in the WSN (Wireless Sensor Network) uplink gateway and along with them a few implementation environments based on open source software and low-power hardware were discussed.
