Abstract

In energy resource constrained networks, the network lifetime can be enhanced by optimally allocating energy resource among users based on the available channel state information and the residual energy information at each node. In this paper, we propose the relay selection scheme and power allocation scheme to maximize the network lifetime in wireless relay networks with capacity constraint. The computer simulation results show that the proposed scheme increase the network lifetime in comparison to the conventional schemes.

에너지 자원이 제한된 네트워크에서는 채널 상태 정보와 남은 에너지 정보를 기반으로 에너지자원을 각 유저들에게 최적으로 할당함으로써 네트워크의 수명을 향상시킬 수 있다. 본 논문에서는 전송 용량을 만족시키면서 네트워크의 수명을 최대화하도록 전송에 참여하는 중계기를 선택하고 전송 전력을 할당하는 기법을 제안한다. 모의 실험을 통해 제안된 기법이 기존 기법에 비해서 수명을 증가시키는 것을 보인다.
