This article has been retracted at the request of the Editor-in-Chief due to extended similarites with an unpublished paper, written by other authors, that was submitted (but not yet published) to several other journals and was probably leaked during the review process.  The authors of the unpublished paper contacted the Editor-In-Chief with the above claim after the publication of this issue and ETASR has contacted several of the journals mentioned and the investigation resulted in the confirmation of the report. The authors of this paper failed to provide any reasoning regarding the case.

Additional Value

We discuss how a short-range wireless communication service implemented for modern mobile communication devices can provide additional value for both the consumer and the service/product provider. When used as an information search tool, such systems allow services and products being promoted at the location they are available. For the customer, it may provide a “digitally augmented vision”, an enhanced view to the current environment. With data filtering and search rules, this may provide a self-manageable context, where the user's own personal environment and preferences to the features available in the current surroundings cooperate with a direct connection to the web-based social media. A preliminary design for such service is provided. The conclusion is that the method can generate additional revenue to the company and please the customers' buying process. In addition to the marketing, the principles described here are also applicable to other forms of human interaction.

The substrate integrated waveguide (SIW) structure is the candidate for many application in microwave, terahertz and millimeter wave application. It because of SIW structure can integrate with any component in one substrate than others structure. A kind components using SIW structure is a filter component, especialy bandpass filter. This research recommended SIW bandpass filter using rectangular open loop resonator for giving more selectivity of filter. It can be implemented for short range device (SRD) application in frequency region 2.4 - 2.483 GHz. Two types of SIW bandpass filter are proposed. First, SIW bandpass filter is proposed using six rectangular open loop resonators while the second SIW bandpass filter used eight rectangular open loop resonators. The simulation results for two kinds of the recommended rectangular open loop resonators have insertion loss (S<sub>21</sub> parameter) below 2 dB and return loss (S<sub>11</sub> parameter) more than 10 dB. Fabrication of the recommended two kind filters was validated by Vector Network Analyzer. The measurement results for six rectangular open loop resonators have 1.32 dB for S<sub>21</sub> parameter at 2.29 GHz while the S<sub>11</sub> parameter more than 18 dB at 2.26 GHz – 2.32 GHz. While the measurement results has good agreement for eight rectangular open loop resonators. Its have S<sub>21</sub> below 2.2 dB at 2.41 – 2.47 GHz and S<sub>11</sub> 16.27 dB at 2.38 GHz and 11.5 dB at 2.47 GHz.

Bluetooth technology aims at allowing short-range communication between portable and/or fixed devices. It uses short-range radio links to replace cables between Bluetooth-enabled devices. In this way, it is similar in purpose to the Infrared Data Association (IrDA), however, Bluetooth is a radio frequency (RF) technology utilizing the unlicensed 2.5 GHz industrial, scientific, and medical (ISM) band. The key features of Bluetooth technology are robustness, low power and low cost with its primary market for data and voice transfer between communication devices and PCs. In this project, a simulation study is done with three major goals in mind: (i) to gather expertise on and evaluate a Bluetooth simulation tool called Bluehoc for further use, (ii) to gather measurements of some Bluetooth characteristics such as throughput in post connection state and (ii) to describe a model that can be used to get maximum throughput for voice and data applications. We also review some of the key aspects in Bluetooth simulation and present models of the Bluetooth devices to get maximum throughput. We show that user data transfer rate (throughput) between Bluetooth master and slaves is effected by distance, number of slaves and slave's start time.

In extremely inhabited countries like India, the population increases day by day because of this problem so many new types of the innovations are developed but in this project mainly focus on the automobiles. For industry reputation purpose car are made with high boost engines which is nearly speed equal to the trains. Due to this over speed so many accident will happen so many lives will lose. Even when the vehicle is travel in unpopular area if there is any accident happen it intimate to the relatives, hospitals and as well as the polis near by the location. In this project first it detects the output from the sensor and that sensor gives the disturbances happen in the directions of the vehicle. And this sensor make to communicate with the other people by using cross communication devices it particularly dedicated for the short range communication. Presently this technology is used in V2V communication .But in this project we mainly focus on the getting the location from the user devices to any other mobile number which are registered before. Major part of the paper we designed in the Verilog implementation whenever the input crosses the threshold voltage it automatically send the information to the user

K Band

In this paper, an offset posts K-band bandpass filter has been designed using substrate integrated waveguide (SIW). SIW is formed inside a dielectric material by applying a top metal over the ground plane and trapping the structure on either side with rows of plated vias. SIW is effective and efficient solution in waveguide technique. The slotted windows are cut in tapered transition of SIW filter to attain low loss. The proposed filters are designed at 23 GHz center frequency. The simulated results exhibit low losses and sharp roll off characteristics in pass band. There is good agreement between the simulated results and the experimental results. The proposed filter is suitable for use in microwave communication devices.
