Wireless sensor networks (WSN) have attracted an increasing attention, therefore, the number of WSN deployments is expected to grow rapidly in the near future. Sensors can be deployed in various environments to monitor and collect information. Most current research is interests in the application layer to develop a WSN with various applications. In this paper we design an application-layer approach for a WebService Gateway to interact with WSN. In our proposed architecture, the gateway manages the service consumption. This architecture intended to support heterogeneous WSN protocols.

Characterization of a metamaterial based on an S-Shaped resonator and a feeding transmission line using a new measurement technique is studied in this paper. First, the metamaterial is designed and simulated using conventional methods. Then, it is fabricated on microstrip and excited by using a microstrip transmission feedline. Measurements were carried out using a vector network analyzer by (SubMiniature version A) SMA coaxial terminations without needing any waveguide transmission lines. For both simulated and measured results, the effective constitutive parameters are retrieved and analyzed. Results show the practicality and feasibility of the proposed measurement method in the characterization of metamaterials for microstrip based microwave circuit applications.

The physical basis for tumor detection with microwave imaging is the contrast in dielectric properties of normal and malignant tissues. Confocal microwave imaging involves illuminating the target with propagating electromagnetic waves using an antenna, and then synthetically focusing reflections from the target. The detection of malignant tumors is achieved by the coherent addition of returns from these strongly scattering objects. In this paper, we demonstrate the feasibility of detecting and localizing small (<;1 cm) tumors or inhomogeneous cells using a radiating patch antenna.

In this work, we focus on the conversion part of a rectenna for wireless power transmission. We simulate and optimize a conversion circuit designed to operate in systems requiring relative high voltage (>15V) and high power (of about 0.5W). Furthermore, we propose a solution to reduce the surface of this circuit.

To avoid Network congestion problematic, 3GPP has developed a new cellular standard based packet switching allowing high data rate, 100 Mbps in Downlink and 50 Mbps in Uplink, and having the flexibility to be used in different bandwidths ranging from 1.4 MHz up to 20 MHz, this standard is termed LTE (Long Term Evolution). Beyond the improvement in bit rate, LTE aims to provide a highly efficient, low latency, spectrum flexibility and high capacity to avoid network congestion. The purpose of this paper is to analyze the congestion avoidance capacity for LTE Network. The performance analysis is conducted in terms of system throughput, delay, and Packet Loss Ratio, using different scheduling algorithms implemented at the LTE base station (PF, MLWDF and EXP/PF schedulers).

1980 marked the start of a boom in radiofrequency identification (RFID) technology, initially associated with a growing need for traceability. In view of the technological progress and lower costs, RFID's area of application became much broader and, today, multiple business sectors take advantage of this technology. But in order to achieve the maximum benefits of RFID technology, the RFID information collected should be useful, for this it is necessary that we can collect it and deliver it in the best conditions for the whole applications that have need of its exploitation, for that a dedicated middleware solution is required to ensure the collection of RFID information and their integration in an information systems. The issues and key points of this integration as the description of the RFID technology will be summarized in the present paper, with a new middleware architecture. We focuses mainly on components, and design of our middleware MedRFID, solution developed in our Lab, and which integrates mobility and provides extensibility, scalability, abstraction, ease of deployment and compatibility with IATA standards and EPCglobal standards.

In this paper, design of two rectangular dielectric resonator antenna (DRA) array is presented for wireless local area networks (WLAN) applications (in the dual frequency range 5.15-5.35 GHz and 5.72-5.85 GHz). The DRA array is excited by microstrip feed line through a single slot located in the ground plane. The numerical analysis is carried out based on the finite-difference time-domain (FDTD) method. The numerical results in term of return losses and radiation patterns of the dielectric resonator (DR) antenna operating in TE111 mode are presented and compared with those of a commercial electromagnetic software HFSS. A good agreement between the two simulated results was obtained.

In this paper we present a new class of dual-band filters based on near-zero propagation - a new paradigm emerging from recent developments of metamaterials. By using two different metamaterial unit cells and by properly coupling them to a microstrip host, permittivity- and permeability-near-zero propagation is achieved at two different frequencies, thus allowing the design of dual-band filters with arbitrary positioned passbands. At the same time, due to specific properties of NZ propagation, such filters will exhibit low insertion loss and good selectivity, as well as a reduced variation of group delay in comparison to the conventional solutions.

This paper presents a new efficient numerical formulations procedure to predict the responses of a N-poles Chebyshev parallel-coupled Microstrip bandpass filter for wireless communication technologies. Based on the transmission line theory approach, these numerical formulations have been developed using the mathematical analysis concept to predict the desired s-parameters of the desired filter. To validate the theoretical method developed in this work, a third and a second order parallel coupled microstrip band pass filters for WiMAX and ISM band respectively have been fabricated and measured. The measured scattering-parameters show a very good agreement with predictions by the theoretical responses, which validates the design procedure of the proposed filter.
