In this paper, we propose a novel approach for constructing the first-order differentiator. It has been shown recently that an efficient FIR wideband differentiator can be synthesized when applying the multirate and frequency-response masking (FRM) techniques. The overall signal processing task is shared between a very low-order differentiator and an FIR half-band filter. The novelty of this paper...
ECOFRAME is a WDM optical packet ring that offers optical transparency and WDM statistical multiplexing and is a promising solution for the future metropolitan area networks. The optimal design of ECOFRAME ring requires the planning of the resources, i.e., wavelengths and receivers. However, the packet-nature of the ring requires a verification of the stability of the design, i.e., that the queueing...
An amplitude equalized C-section based all-pass dispersive delay structure (DDS) is proposed and experimentally demonstrated by cascading the DDS with a resistive transmission line network. Using such resistive networks, the frequency dependent dielectric and conductor losses of the transmission lines are equalized. This leads to a flat transmission response of the DDSs which is critical for efficient...
Time synchronization represent the most critical piece of infrastructure in any distributed system, especially for Wireless Sensor Networks (WSNs) which make particularly extensive use of synchronized time. Many applications of WSN need local clocks of individual sensor nodes to be synchronized. Almost any form of sensor data fusion or coordinated actuation requires synchronized physical time for...
Deployment of Broadband Internet is currently one of the most important global issues. Plans for developing agendas are very ambitious but implementation is not as expected. In this paper authors analyse broadband growth and its limitation factors, delays and gaps. Using logistic growth function, the growth limit, delay and gap for Serbia is calculated in reference to the average of EU countries....
This paper will analyze the coverage city of Nis with DVB-T2 signal from locations Gorica (Apelovac) and selection of protective intervals in the SFN network.
In this paper performances of the Multi Channel Routing (MCR) protocol are analyzed. This is a protocol for multi-channel multi-interface wireless mesh network (WMN), so it must have a certain channel switching algorithm. The main goal of the routing protocol in WMN is to achieve the best possible quality and efficiency of data transmission between the nodes in the network. Because of that, different...
In this paper, we propose a framework for SLA specification and negotiation in next generation networks. The framework encompasses a general service level specification format and conformance matching rules. The proposed specification format allows administrators to describe service classes in their own domains independently of the network technology and the applied QoS model. We further define and...
The paper presents preliminary results of a European project, with the goal to design an integrated system for delivering real-time travel and traffic information on mobile navigation devices. The service matches together multiple data formats and operates via a Common Agreed Interface (CAI) to achieve data fusion from different information sources. The updated information is used to create specific...
In this paper we are discussing the “pacemakers” for cyclic and goal directed movements in humans with central nervous systems injury/disease that are based on electrical stimulation. The system that restores or augments movement is termed Motor Neural Prosthesis (MNP). The novelties needed to make MNP compatible with the richness of living systems must be based on better understanding of the effects...
The paper describes a video streaming application build to evaluate session continuity over wireless hybrid access networks in vertical handover (VHO) conditions. The results showed us which components have to be improved. Further developments will address these improvements.
In this paper we proposed the novel multiband unit cell which consists of two types of split-ring resonators coupled to microstrip line: the broadiside coupled and the single split-ring resonator. Novel unit cell exhibits two left-handed bands that can be shifted by twisting split rings for certain angle or by changing their lengths. This unit cell is suitable for design of multiband frequency scanning...
