Abstract

One of the most important issues in Wireless Sensor Networks is to save energy of the sensor node. But transmission latency is also the problem to solve for some applications such as military surveillance, object tracking. In these applications sensor node needs to send lots of data in limited time when an even such as object appearance occurs. So a delay efficient data transmission method is required. In this paper we propose a MAC protocol adequate for those applications. This paper proposed a low delay data transmission mechanism for military surveillance in wireless sensor networks. In the MAC protocol, a receiver node sends another beacon frame to sender node after receiving data packet. Using this second beacon frame, fast hop-to-hop transmission can be performed. Results have shown that the proposed MAC control mechanism outperformed RI-MAC protocol in the terms of latency.

무선 센서 네트워크에서 중요한 이슈 중 하나는 센서 노드의 에너지 절약이다. 그러나 군 정찰, 물체 추적과 같은 응용 분야에서는 지연 또한 중요한 문제이다. 이러한 응용에서 센서 노드는 물체가 감지되면 제한된 시간 내에서 많은 양의 데이터 패킷을 전송해야 한다. 그렇기 때문에 지연에 효율적인 데이터 전송 방법이 필요하다. 본 논문에서는 이러한 응용에 적합한 MAC 프로토콜을 제안한다. 제안하는 MAC 프로토콜은 무선 센서 네트워크에서 군 감시 정찰을 위한 저 지연 데이터 전송 메커니즘이다. MAC 프로토콜에서, 수신 노드는 송신 노드에서 데이터 패킷을 수신한 후 두 번째 비콘 프레임을 보낸다. 이 두 번째 비콘 프레임을 사용하여 빠른 hop-to-hop 전송이 가능하다. 성능분석을 통해 제안된 MAC 프로토콜과 RI-MAC 프로토콜을 비교하였고, 제안된 방법이 지연에 더 효율적이다.
