Abstract

In wireless sensor networks, data packets are send to the sink node. So traffic increases near the sink node. This causes delay and collision. To solve this problem, the proposed mechanism used half rotation antenna. By using a half rotation antenna, the delay of data packets can be reduced. Also we propose a method to efficiently use the energy of the node using BRN(backup receiver node) and increase the lifetime of the entire networks. Our numerical analysis and simulation results show that our mechanism outperforms RI-MAC protocol in terms of energy consumption and transmission delay.

무선 센서 네트워크에서 데이터 패킷은 싱크 노드 방향으로 전송되기 때문에 싱크 노드에 가까운 센서 노드들은 데이터 트래픽이 증가한다. 이러한 문제로 인하여 데이터 패킷은 전송 지연되거나 손실될 수 있다. 이러한 문제를 해결하기 위하여 본 논문에서는 half rotation antenna를 사용하는 방법을 제안한다. half rotation antenna를 사용함으로써 데이터 패킷의 전송 지연을 감소시킬 수 있었다. 또한 BRN(backup receiver node)를 사용하여 센서 노드들의 에너지를 효율적으로 소모할 수 있었고, 네트워크 전체 수명을 증가시키는 효과를 볼 수 있었다. 제안하는 방법은 RI-MAC 프로토콜과 성능 분석을 하였으며, 기존의 RI-MAC 프로토콜에 비해 에너지 소모 및 지연에 더 좋은 성능을 보였다.
