DF中继网络中的分布式机会信道接入策略
Distributed opportunistic channel access strategy in DF relay networks
摘要
Abstract
Considering the two limitations of scenario assumption and performance optimization in distributed opportunistic channel access under the continuous transmission rate, a distributed opportunistic channel access strategy is proposed in DF relay networks under the discrete transmission rate. The proposed strategy maximizes the system average throughput with the instruction of optimal stopping theory. By optimizing the second-hop transmission time in DF relay networks completely, the total transmission time is reduced, and the system performance is improved. Compared with the current strategy, simulation result demonstrates the validity of the proposed strategy in system average throughput.关键词
