【摘要】：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.
[Abstract]:In order to improve the energy utilization of the heterogeneous network, a new parallel multipath transmission scheme based on energy perception is proposed, which is called MTCPenergy-aware MPTCP-based content delivery scheme. Based on the Linked Increases algorithm, the end-to-end energy consumption model is used to obtain the energy consumption index of the whole network, and then the congestion window size is adjusted in real time according to the principle that the increase of congestion window is inversely proportional to the energy consumption of the path. According to the relation between throughput and congestion window, the throughput of each access network is obtained. Finally, according to the ratio of the throughput of each access network to the throughput of the core network, the optimal shunt ratio of each access network is considered. The simulation results show that the proposed scheme can not only guarantee load balance and fairness between single TCP flow and MPTCP flow, but also effectively improve the energy utilization rate of the whole network under the condition that the network throughput is basically unchanged.
