Abstract: Optical Code-Division Multiple-Access (OCDMA) have flourished as successful schemes for expanding the transmission capacity as well as enhancing the security for OCDMA. Optical code-division multiple-access is proposed as a natural solution to achieving asynchronous, high-speed connectivity in a local area network environment. Optical CDMA is shown to be competitive with other networking technologies such as WDMA and TDMA, but has the benefit of more flexibility, simpler protocols, and no need for centralized network control. The purpose of this paper is to review the literature on OCDMA overlay systems, including our approach of one dimensional coding of SAC OCDMA. Furthermore, an essential background of OCDMA, recent coding techniques and security issues are also presented.The limitations of one-dimensional optical orthogonal codes for CDMA have motivated the idea of spectral spreading in both the temporal and wavelength domains. If the constraints on constant weight in these two-dimensional codes are relaxed, differentiated levels of service at the physical layer become possible. Areas for further research are suggested which may allow quality of service levels to be guaranteed at the physical layer.
Keywords: OCDMA, multiple access, OOC(Optical orthogonal code), WDMA+CDMA, Multiple weight OOC.

Abstract: Near Field Communication (NFC) is one of the latest wireless communication technologies, making possible variety of novel services particular in the security aspect. This paper presents an idea to implement a security system using a new technology called the Near Field Identification (NFID) which uses the combined principle of NFC and RFID (Radio frequency Identification). The security system thus developed will have a wide advantage over the existing biometric systems that are in practice and will provide a highly secure environment in the near future.

Abstract: In this work, we describe an effective video communication for wireless transmission of H.264/AVC medical ultrasound video over mobile WiMAX networks. Medical ultrasound is encoded using error resilient encoding in which, the quantization levels are varied according to the function of the diagnostic significance of image region. We explain how our proposed system allows for the transmission of high-resolution clinical video which is being encoded at the clinical acquisition resolution and then decoded with low delay. We perform this functional concept by using OPNET simulations of the mobile WiMAX medium and also considering some of the physical layer characteristics also such as service prioritization classes, different types of modulation being performed, fading channel's conditions, coding schemes and their types and mobility.We are encoding the ultrasound videos at 4CIF(704×576)resolution to provide high level of clarity. The video quality assessment is being done based on both of their evaluations in objective and subjective manner.

Abstract:Wireless application can work better if the supporting component especially the antenna can transmit and receive the power with low losses due to the misalignment. Reducing the power losses caused by misalignment can be performed with the circularly polarized antenna. We proposed the circularly polarized antenna, with 40mm x 40 mm in dimension and FR-4 substrate with the dielectric constant of 4.4. The microstrip line fed and the power divider method were used to get orthogonal mode. From the measurement result, the antenna can work at frequency range of 1.9 up to 2.5 GHz omnidirectionally and has an axial ratio value below 3 dB.

Abstract: Sensor networks are strong proposal in almost every wireless application. Secure and reliable communication without expense of throughput is always a key concerned. Although trust based cost efficient scheme have already employed but use of same congested route leads to degradation of quality of service due to frequent usage of trusted congested route. Our research work is based on a fact that high energy node are always stable and less prone to congestion because of their less usability in routing path. Propose article presents applicability of energy level on cost efficient trusted neighbors to select high energy nodes to construct less congested route for data transmission to provide throughput enhancement and improving quality of service along with secure communication.

Abstract: Now a day's experiments/labs remote access via virtual instrumentation concept is very much appreciated due to time saving, without experimental set-up availability and remotely accessed. I have created remote access for my experimental set-up (MIMO water level control system in LABVIEW environment) with the help of SCCT (Smartphone & Cross-platform Communication Toolkit) platform on LABVIEW software. It's fully automatic and can be accessed and controlled by subscriber any time anywhere.

Abstract: Diabetic retinopathy (DR) is a sight threatening complication due to diabetes mellitus that affects the retina .The blindness due to DR can be prevented if detected early enough for treatment.Hence screening for early stage of DR is very important. An ophthalmologist uses an ophthalmoscope to visualize the blood vessels and his or her brain to detect the DR stages. The above pathology-based method is time consuming and often requires fluorescein angiograms for accurate diagnosis. It requires highly trained and skilled clinicians to perform the DR severity grading method. In this paper we have proposed a low cost retinal diagnosis system which can aid an ophthalmologist to quickly diagnose various stages of diabetic retinopathies.

Abstract: A Microstrip loop resonator sensor designed to determine the dielectric constant of a liquid is proposed. The resonator sensor designed for 1GHZ for different structure of loop is described. The sensor is implemented using planar microstrip technology. A dielectric material is placed above microstrip ring resonator. As a consequence the near field of the resonator interacts with the material under test (MUT) and the electrical characteristics of the resonator change in relation to the permittivity of the material. The proposed models are extremely compact and experimentally verified by the measurements for liquid sample. A vector network analyzer is used to measure the shift in resonant frequency and the corresponding amplitude of the transmission parameter for the fundamental mode. The design procedure is described and experimental results are reported validating the sensor performance.
Keywords: Frequency shift, Moisture Content, Permittivity, Resonator sensor.

Abstract: This paper presents the design of State Feedback Controller to implement it at Coupled Two Tank Liquid Level System. The liquid level in the coupled tank is controlled by using feedback as required and also to understand the habit and effectiveness of Integral Control State Feedback Controller. The design was implemented using second order system in the coupled tank. The State Feedback Controller is designed using Ackermann's formula based on pole placement method. The Ackermann's method, besides being useful for single-input systems, may also find application to control a multi-input system through a single input. A state feedback control is linear combinations of state variables. State feedback focuses on time-domain features of the system responses. The necessary and sufficient condition to be satisfied by the system for arbitrary pole placement is the system be completely state controllable.
Keywords: Integral control State feedback controller, Ackermann's formula, Coupled two tank liquid level system, Pole Placement technique.

Abstract: Remote data access and machine to machine communication are some of the value added services made possible by the GSM communication technology. With this service, automated access to records, information and updates can be achieved by the use of the GSM short message system (SMS) queries. This work presents the development of a remote access platform for remote access to a database. The system utilizes the GSM-SMS technology and an interactive voice recorder system to access data. The database contains students result, financial status and information on the number of exeats taken. This data is accessed by calling dedicated phone number and following the voice prompt voice prompt, the user is able to access the desired information from the database. Once the required data is accessed, the GSM module transmits this query result back to the caller in SMS format. The system provides a cost effective channel for accessing data from remote databases.
