Effects of Number of Relays on Achievable Efficiency of Magnetic Resonant Wireless Power Transfer

IEEE Transactions on Power Electronics (2019)

Junseob Lee Kisong Lee

In magnetic resonant wireless power transfer (WPT), relays are placed between a transmitter and a receiver as a means of increasing both the operating distance and the power transfer efficiency, but this makes the analysis of the WPT system more complicated. In this letter, we derive a mathematical expression for the power transfer efficiency with an optimal load resistance based on an equivalent circuit model, and analyze the effects of varying the number of relays on the power transfer efficiency that can be achieved. By means of circuit-level simulations and experiments under a variety of scenarios, we verify the accuracy of our analysis, and we also confirm that there is an optimal number of relays for maximizing the achievable power transfer efficiency for a given end-to-end distance.

Jamming Power Control for Secure Communication via Untrusted Relay with Imperfect Channel Estimation

2015 IEEE Global Communications Conference (GLOBECOM) (2019)

Junseob Lee Kisong Lee

This paper investigates a secure communication via an untrusted relay with channel estimation error, in which a destination-assisted jamming strategy is adopted to prevent the relay from recovering a source signal. In the presence of channel estimation error in the relay-to-destination link, a destination cannot decode the source signal as well as eliminate a jamming signal perfectly, which causes a serious degradation in secrecy performance. Therefore, it is required to propose an effective strategy to determine jamming power level for maximizing secrecy rate. Under the assumption of high transmit signal-to-noise ratio, we derive the closed-form expression of a suboptimal jamming power ratio and propose an adaptive jamming power allocation which can be operated in practical systems. Numerical results confirm that the proposed scheme outperforms the conventional scheme in terms of secrecy rate.

A Design and Simulation of Mobile RFID Contents Expression Language for Bus Guidance Services

The Journal of the Korean Institute of Information and Communication Engineering (2005)

Yeon Dong-Hee Kim Yong‐Woon Sang-Keun Yoo Junseob Lee Hyoung-Jun Kim

The RFID (Radio Frequency Identification) technology is a non-contact identification system which can wireless reading of information, by attaching tags on objects; various applications of the technology are feasible throughout a dive of industries, and researches are currently under way. Recently, in connection with the wireless communication industry, application service models conveying information to the users through mobile devices with RFID readers were suggested. Such application service based on mobile RFID technology requires schema that models the form of data. Therefore, this study analyzes the mobile RFID application service model that will be serviced in the mobile environment, functions and elements of the protocol, and the interface, designing a language to process the data and express contents in the said service models, and we simulated the service for test it.

An integrated mobile RFID service architecture between B2B and B2C networks

International Conference on Advanced Communication Technology (2007)

Sang-Keun Yoo Junseob Lee Yong‐Woon Kim Hyungjun Kim

This paper proposes mobile RFID service architecture using RFID tags of B2B. To use RFID tags of B2B in mobile RFID service network, two approaches may be available. One is that network entities in mobile RFID service network access to network entities in B2B network and uses contents of B2B for mobile RFID service. The other is that only UII in RFID tag is used in mobile RFID service which does not require access to network entities in B2B. For these purposes this paper proposes mobile RFID service gateway. Also the requirements and the functions of the service gateway are defined.
