    Keywords : Acoustic echo cancellation; Room modeling; Reverberation time; Signal to noise ratio; Echo return loss enhancement;

    Abstract : The whole dimension of communications has been changed by the rapid growth of technology. Today people are more interested in hands-free com-mucation, which makes use of loud speaker and high gain microphone, in place of the old modeled wired telephone. READ MORE

  3. 22. Cognitive WSN access based on local WLAN traffic estimation

    University essay from KTH/Kommunikationsnät

    Author : Marcello Lagana; [2011]
    Keywords : ;

    Abstract : 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.

In the early days in order to remove the interference problem, the spectrum was assigned statically. READ MORE

  6. 25. Security issues with Mobile IP

    University essay from Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Author : Abdel Rahman Alkhawaja; Hatem Sheibani; [2011]
    Keywords : Mobile IP;

    Abstract : With a rapid growth in wireless technology in recent years, Mobile IP has become very important for consumers and businesses by providing mobility based on IP addresses using several applications, which keep the employees connected with each others with critical information. In mobile IP the node can change its location by maintaining the same IP address and keep connected to the internet, which solves the issue of terminating the communication once it moves. READ MORE
