This paper analyzes signaling traffic generated by IP Multimedia Subsystem (IMS) when deployed within a hybrid WLAN IEEE 802.11 and CDMA2000 networks to provide wireless and broadband services to users. IMS provides a services infrastructure to 3G networks and beyond and delivers the capability to maintain sessions among calling parties. IMS is under(More)
In this paper, we propose a channel-assignment algorithm at the Access Points (APs) of a wireless local area network (WLAN) in order to maximize signal-to-interference ratio (SIR) at the user level. We start with the channel assignment at the APs, which is based on minimizing the total interference between APs. Based on this initial assignment, we calculate(More)
This paper proposes a transceiver system for automatic tracking and dynamic routing for free space optical (FSO) communication. The proposed transceiver architecture has M transmitters and M receivers in a M × M configuration that can dynamically orient themselves at different angles to establish a link between two transceivers. A request to setup a(More)
BACKGROUND An evaluation of progress with participatory approaches for improvement of health knowledge and health experiences of disadvantaged people in eight Districts of Eastern Nepal has been undertaken. METHODS A random selection of Village Development Committees and households, within the eight Districts where participation and a Rights-based(More)
This paper demonstrates the performance of Ultra Wideband (UWB) systems in the Stochastic Tapped Delay Line (STDL) model of the UWB channel with RAKE receiver. System models are based on Direct Sequence Code Division Multiple Access (DS-CDMA) principle. The system has been studied in presence of multiple user interference and Gaussian noise. During the(More)
