Abstract

In this paper, we propose a distributed transmit power control algorithm for optimal end-to-end throughput in wireless multihop networks. Considering a solidarity property of link rates consisting of a multihop link and the fact that the multihop end-to-end throughput is determined by the minimum link rate, the proposed scheme controls the transmit power to make all link rates be equal and so maximizes the end-to-end throughput of multihop link. In addition, in the proposed scheme the transmit node calculates its transmit power autonomously in a distributed manner just through the information sharing with its neighbor nodes and so decreases the information sharing overhead. Simulation results show that the proposed scheme achieves significant improvements in terms of end-to-end throughput and power consumption compared with the conventional maximum equal power allocation scheme.

이 논문에서는 무선 멀티홉 네트워크 환경에서 종단간 최적 전송률을 제공하기 위한 분산 송신전력제어 방안을 제안한다. 제안 방안은 멀티홉 구성 링크들의 전송률이 갖는 연대 특성과 멀티홉 종단간 전송률이 최소 링크 전송률에 의해 결정된다는 점을 고려하여, 멀티홉 구성 링크들의 전송률이 모두 같아지도록 송신전력을 제어함으로써 종단간 전송률을 최대화 한다. 또한 제안 방안은 이웃단말과의 정보 공유만을 가지고 단말 스스로 송신전력 값을 계산하는 분산 방식으로 송신전력 제어에 필요한 정보 교환 오버헤드를 줄인다. 시뮬레이션 결과 제안 방안은 고정된 최대 송신전력 값을 사용한 기존 방식 대비 종단간 전송률과 전력소비 측면에서 큰 성능이득을 보여준다.
