초록
센서노드의 에너지를 절약하는 것은 네트워크 수명을 늘리기 위해 필요하다. 센서의 에너지는 파워를 교체할 수 없기 때문에 매우 중요하다. 에너지를 절약함으로써 네트워크의 자원을 절약하고 더 오랫동안 사용할 수 있다. 이 논문에서는 베이스 스테이션을 활용하여 라우팅 프로토콜을 최적화하기 위한 프로토콜인 BSAH 를 제안하였다. BSAH 는 BeamStar 처럼 베이스스테이션이 안테나의 방향을 고려하여 센서를 나눈다. BSAG 는 PEGASIS 나 CHIRON 보다 25%에서 30% 정도 우수한 성능을 보였다.
Preserving energy of sensor node in wireless sensor network is an effort to prolong the lifetime of network. Energy of sensor node is very crucial because battery powered and irreplaceable. Energy conservation of sensor node is an effort to reduce energy consumption in order to preserve resource for network lifetime. It can be achieved through efficient energy usage by reducing consumption of energy or decrease energy usage while achieving a similar outcome. In this paper, we propose optimization of energy efficient base station assisted hierarchical routing protocol in wireless sensor network, named BSAH, which use base station to controlled overhead of sensor node and create clustering to distribute energy dissipation and increase energy efficiency of all sensor node. Main idea of BSAH is based on the concept of BeamStar, which divide sensor node into group by base station uses directional antenna and maximize the computation energy in base station to reduce computational energy in sensor node for conservation of network lifetime. The performance of BSAH compared to PEGASIS and CHIRON based of hierarchical routing protocol. The simulation results show that BSAH achieve 25% and 30% of improvement on network lifetime.
