为提高整个异构网络的能量利用率,提出一种新的基于能量感知的并行多径传输方案ea MTCP(energy-aware MPTCPbased content delivery scheme).方案以Linked Increases算法为基础,利用端对端能耗模型获得整个网络的能耗指标,再按照拥塞窗口增加量与路径能耗量的开方成反比例的原则实时调整拥塞窗口大小,并根据吞吐量与拥塞窗口的关系得到各接入网的吞吐量,最后按照各接入网的吞吐量与核心网所能承载吞吐量之比作为各接入网的最优分流比进行分流.仿真结果显示,本方案既能保证负载均衡和单条TCP流与MPTCP流的公平性,又可在网络吞吐量基本不变的情况下,有效提升整个网络的能量利用率.
In order to improve the energy utilization rate of heterogeneous networks, this paper proposes a new Energy-aware MPCP-based content delivery scheme (eCPCP) based on energy-aware MPTCPbased content delivery scheme Consumption model to obtain the energy consumption indicators of the entire network, and then adjust the size of the congestion window in real time in accordance with the principle that the congestion window increases and the square root of the energy consumption of the path is inversely proportional, and obtains the throughput of each access network according to the relationship between throughput and congestion window Finally, according to the throughput of each access network and the core network can carry the ratio of the throughput as the optimal distribution ratio of each access network to divert the simulation results show that this scheme can ensure load balancing and a single TCP flow and MPTCP flow fairness, but also in the network throughput basically unchanged, effectively improve the energy efficiency of the entire network.
