  1. 11. Energy-efficient enhancements for IEEE 802.11 WLANs : On the way to enable Cellular/Wi-Fi networks interworking

    Master-uppsats, KTH/Radio Systems Laboratory (RS Lab)

    Författare :Fernando Valdenebro González; [2014]
    Nyckelord :energy-efficiency; WLAN; Wi-Fi; heterogeneous networks; seamless handover; network discovery; energieffektivitet; WLAN; Wi-Fi; avbrottsfri handover; nätverksidentifiering; heterogena nätverk;

    Sammanfattning : Globally, the number of mobile broadband subscriptions is growing and the amount of mobile data traffic is expected to continue to grow rapidly. In the next five years the number of smartphone subscriptions is expected to more than double, while the amount of mobile traffic per active subscription per month of these subscribers is expected to nearly quadruple.

  3. 12. IPv6 Monitoring and Flow Detection

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för datavetenskap och kommunikation

    Författare :Theodros Ayichiluhm; Vivek Mohan; [2013]
    Nyckelord :IPv6; Monitoring; Windows; Linux;

    Sammanfattning : IPv6 Privacy extensions, implemented in major operating systems, hide user’s identity by using a temporary and a randomly generated IPv6 addresses rather than using the former, EUI-64 format where the MAC address is part of the IPv6 address. This solution for privacy has created a problem for network administrators to back-trace an IPv6 address to a specific MAC address, since the temporary IP address used once by the node is removed from the interface after a period of time.

  4. 13. Synchronized MAC layer for ultra-wideband wireless sensor network : Design, implementation, analysis, and evaluation

    Master-uppsats, KTH/Kommunikationssystem, CoS

    Författare :Alessandro Monge; [2013]
    Nyckelord :IEEE 802.15.4a; synchronization; time delay of arrival; ultra-wideband; IEEE 802.15.4a; synkronisering; tidsfördröjning för ankomst; ultrabredbandsteknik;

    Sammanfattning : The necessity of interconnecting objects more and more, possibly with high mobility, has pushed the telecommunications industry to recently develop new wireless standards in order to guarantee tracking of devices and to provide integration with well-known worldwide networks such as the Internet. Within these standards the role played by power consumption is implicit, hence power consumption needs to be as low as possible in order to fulfill long-life requirements and to offer the opportunity of locating and moving smart objects in the coverage area while relying only on batteries as the device's power source.

  5. 14. Scalable Data Collection for Mobile Wireless Sensor Networks

    Master-uppsats, KTH/Kommunikationsnät

    Författare :Navid Hassanzadeh; [2012]
    Nyckelord :;

    Sammanfattning : In the near future WSNs (wireless sensor networks) which consist of tiny wireless embedded systems will be an inseparable part of our daily lives. Data collection, collecting data from a large number of sources to one or more base stations, is a typical application for WSNs. LÄS MER

  7. 15. Cognitive WSN access based on local WLAN traffic estimation

    Master-uppsats, KTH/Kommunikationsnät

    Författare :Marcello Lagana; [2011]
    Nyckelord :;

    Sammanfattning : The recent growth in the deployment of wireless networks that access the unlicensed ISM bands has introduced the issue of co-existence between different kinds of wireless technologies. In this work we address the enhancement of the performance of the low-cost Wireless Sensor Network nodes competing for spectrum access with the WLAN devices, that are more powerful in terms of transmission and computational power.
