Abstract

Though a mobile device is equipped with a number of wireless communication interfaces in general such as Zigbee, Bluetooth, Wi-Fi, 3G, it uses only one interface for a specific service. In this paper, we propose a mechanism of adaptive switching between wireless communication interfaces in order to efficiently use various communication interfaces. Depending on the application service and the characteristics of wireless communication interface, mobile devices select an appropriate wireless communication interface and may switch to another interface during the service. As a result, power consumption can be reduced and the utilization of communication interface can be improved by using this mechanism.

일반적으로 하나의 모바일 디바이스에 직비, 블루투스, 와이파이, 3G 와 같은 무선통신 인터페이스가 여러 개 구비되어 있지만 서비스를 이용할 때는 고정적으로 하나의 통신 인터페이스만 이용하고 있다. 본 논문에서는 다양한 통신 인터페이스를 효율적으로 사용하기 위하여 무선통신 인터페이스들 간의 능동적인 전환 기법을 제안한다. 이 기법은 통신 서비스에 따라 각 무선통신 인터페이스의 특징을 살려서 적합한 무선통신 인터페이스를 선택하고 전환하는 기법으로서, 전력 소비를 줄일 수 있고 인터페이스의 효율성을 높이는 효과가 있다.
