Abstract

In the general transmission power control model that is used for wearable sensor systems, if RSSI value gets out of the Target RSSI Margin, then the sink node finds new transmission power by using TPC(Transmission Power Control) Algorithm. At this time, the sink node sends the control packet to the sensor node for delivering the newly calculated transmission power. However, when the wireless network channel condition is poor, even it is consuming a lot of control packets, the sink node could not find an appropriate transmission power so it only waste of energy. Therefore, we proposed a new control packet transmission decision method that the sink node changes the transmission power when the wireless network channel condition is stabilized. It makes waste of energy decline. In this paper, we apply control packet transmission decision method to Binary TPC algorithms and analyze the results to evaluate the proposed method. We propose three methods that judge the state of wireless network channel. We experiment that methods and analysis the results.

웨어러블 센서 시스템에서 사용하는 일반적인 전송 전력 조절 모델에서는 수신 패킷의 RSSI가 Target RSSI Margin을 벗어나면 전송 전력 조절 알고리즘을 이용하여 새로운 전송 전력을 찾는다. 이 때 싱크 노드가 센서 노드에게 새로이 계산된 전송 전력을 전달하기 위해 제어 패킷을 보낸다. 그런데 무선 네트워크의 채널 상태가 좋지 않을 때는 제어 패킷을 많이 소모하면서도 적정 전송 전력을 찾지 못해 에너지 낭비만 하게 된다. 따라서 본 논문에서 무선 네트워크 채널 환경이 안정적이라고 판단되었을 때 전송 전력을 변경하는 새로운 제어 패킷 전송 결정 기법을 제안한다. 제안되는 기법으로 낭비되는 에너지를 줄일 수 있다. 제안하는 기법을 평가하기 위해 본 논문에서는 Binary 전송 전력 조절 알고리즘에 제어 패킷 전송 결정 기법을 적용하고 그 결과를 분석한다. 채널의 상태를 판단하는 방안을 3가지 제안하여 실험하고 결과를 분석한다.
