  • Clusters-based rendezvousing approach for scheduling the flash crowd
           transmissions over cognitive radio networks

    • Free pre-print version: Loading...

      Authors: Ch. Suneetha, S. Srinivasa Rao, K.S. Ramesh
      Pages: 1 - 11
      Abstract: Rendezvousing the transmissions and radio frequencies is a crucial objective to achieve optimal utilisation of the spectrum bands by secondary users in cognitive radio networks. Many dimensions of research, such as attaining quality of service during transmissions occurring through spectrum bands, optimising security factors to enable fair and trusted transmissions over spectrum bands is happening in the recent past. However, optimising the spectrum band utilisation by rendezvousing the transmissions and radio frequencies of spectrum band as transmission channels is essential against the massive transmissions (flash crowd) framed by multiple users. Concerning this, a batch processing approach called 'clusters-based rendezvousing approach for scheduling the flash crowd transmissions over cognitive radio networks' has proposed in this manuscript. A new distance measuring technique has adapted to perform a clustering process, which has applied on both buffered transmissions and idle radio frequencies. The results obtained from an experimental study indicating the comparatively better performance from the proposed model and, if utilised within the definitive frameworks, can yield better performance results.

  • CPW-fed star shaped UWB antenna with and without band-notch
           characteristics

    • Free pre-print version: Loading...

      Authors: Sarthak Singhal, Amit Kumar Singh
      Pages: 12 - 24
      Abstract: A CPW-fed star shaped slot like monopole antenna with and without ITU-8 band notch characteristics for ultra wideband communication are proposed. They comprise a stage 1 Koch fractal star shaped radiating patch, modified feedline and slot loaded CPW ground plane. The band notch characteristic is achieved by loading the radiating patch with half wavelength long meander line slot. An impedance bandwidth of 3.1-17.6 GHz with band rejection for 8-9 GHz band (ITU-8 band) (S<SUB align="right">11 ≤ -10 dB) is achieved. The band notch characteristic is modeled by an equivalent RLC resonant circuit. The equivalent circuit is validated with simulated input impedance and VSWR results. The proposed antenna provides an average gain of 4.4 dB over the entire band of operation for without band notched antenna. The radiation patterns are also observed to be omni-directional and bidirectional at lower frequencies with some distortions at higher frequencies. Non-band reject antenna configuration provides a fidelity factor of 90% along with a constant group delay over the entire operating band. The effect of various critical parameters on antenna performance is also analysed.

  • On the design and analysis of micro-machined frac truss based fractal
           patch antenna for multiband applications

    • Free pre-print version: Loading...

      Authors: Ashish Kumar, Amar Partap Singh Pharwaha
      Pages: 25 - 34
      Abstract: An optimal design of frac truss based fractal patch antenna for multiband applications devoted to satellite communications is proposed in this paper. The proposed antenna is iterative up to 3rd iteration with a miniaturised size of 15 mm × 27 mm on FR4 substrate of dielectric constant 4.4 and thickness of 1.58 mm. There has been a reduction of 54.2% in the copper material of the patch due to fractal slots which leads to the low cost of the antenna design. The resonating behaviour of the proposed design is verified at different thicknesses of the FR4 substrate and other substrates. Limitations of the high index substrate like silicon have been overcome by the process of micro-machining. The proposed design resonates at 6.4, 8.6, 11.8 and 14.5 GHz with a maximum bandwidth of 1.4 GHz. The simulated and measured results shows quite resemblance and prove to be excellent impedance matching at various frequencies of operation.

  • Design of a parallel coupled microstrip planar band-pass Chebyshev filter
           for 2.4 GHz ISM band application

      Authors: Quazi Mohmmad Alfred, Hashibul Alam
      Pages: 35 - 39
      Abstract: This paper demonstrates the design, simulation and fabrication of edge-coupled microstrip band-pass filter (BPF) at centre frequency around 2.4 GHz. It is very much useful on 2.4 GHz ISM band wireless communications, e.g., GPS, WLAN Bluetooth and WiMax applications. The filter is built on relatively low-cost FR-4 substrate. The theoretically considered range of frequency 2.3 to 2.5 GHz and bandwidth is 200 MHz and Chebyshev filter response with 0.5 dB ripple in pass-band is preferred. The simulation values of cut-off frequency are 2.30 and 2.50 GHz with centre frequency 2.4 GHz and measured values is 2.302 and 2.502 GHz with centre frequency 2.402 GHz. After fabrication, the measurement results show the good agreement with theoretical consideration and simulation results.

  • Comparative investigation on multi-band antenna using FR-4 and

      Pages: 40 - 46
      Abstract: The comparative design and investigation of the multiple resonances are analysed on two substrates using flame retardant FR-4 glass epoxy with the dielectric value of 4.4 and RT-Duroid with the dielectric value of 2.2. To attain the multiple bands for multiple applications with a single antenna is the main aim concluded in this paper. The defected ground structure (DGS) is designed on the ground plane with the combination of slots getting into shaped as E-shape and stacked U-shape. The proposed model has responded to multiple resonances on two substrates. Once the DGS has been inserted, the various parameters are improved such as multiple bands, return loss, gain and bandwidth. The dimensions for FR-4 substrate and RT-Duroid are 30 × 20 × 1.6 mm<SUP align="right">3</SUP> and 30 × 20 × 1.2 mm<SUP align="right">3</SUP>, respectively. The main goal of the proposed antenna is to use it for multiple applications. This can be achieved by tuning the defective ground structure. In this proposed antenna, the 50 ohm line feed technique has been utilised for both designs.

           worm-satin bowerbird optimisation

      Authors: Beledha Santhosh Kumar, Polipalli Trinatha Rao

      Abstract: The cell zooming is used for solving the soft faults to recover the nodes by itself by enabling the sleep mechanism. The fault nodes are determined using the glow worm optimisation. The routing of the packets will be performed through the Satin Bowerbird optimisation. The main objective of the Satin bowerbird optimisation is to perform the multi-objective and it is highly oriented towards the energy conservation. Due to these properties, the Satin bowerbird optimisation is use to define the optimal route based on the energy efficient of the network. Analysis and simulation results show that the (GWO-SBO) proposed algorithm will outperforms than existing TCOMSR and emperor penguin optimisation and flower pollination by maintaining the throughput at 9,000-10,500 bps throughout the network and reduce the energy consumption to prolong the network lifetime and its stability.
