    Computer Vision and Wireless Sensor Networks in Ambient Assisted Living: State of the Art and Challenges

    Due to demographic reasons, the percentage of elderly population in developed countries is rapidly increasing, thus leading to much bigger demand of alternative caring solutions such as Ambient Assisted Living (AAL). This paper presents the recent research trends in AAL, as well as the main challenges to its development. The...

    Amplification of the Multi-Wavelength Signal by Using EDFA With Constant Gain

    The paper deals with the results of EDFA simulation that has been carried out to study the modes of operation and to determine the amplifier parameters' values at which maximum flatness of the gain spectrum curve is obtained. The mathematical model applied is based on the propagation equations and known...

    Performance Analysis of Uplink Packet Schedulers in Cellular Networks With Relaying

    Incorporating relay nodes in cellular networks, e.g., UMTS/HSPA, can prove to be beneficial as for extending coverage as for service enhancement. The latter is particularly important for uplink users at the cell edge which generally suffer from relatively poor service due to signal degradation. In this paper, the authors concentrate...
