摘要 基于流量分配与重分配的算法,提出了一种改进的拥塞流量分配(ECOTA)和有效的拥塞检测和缓解(ECODEM)算法。在衡量了所有路径的能耗与传输延迟之后,选出若干条能耗低、延时短的路径,增加了数据传输的成功率。通过设定阈值与预测的方法对网络中的拥塞区域进行检测,一旦拥塞发生,采用合理重分配流量的方式,使节点能够更快地从拥塞状况中恢复出来,并保证拥塞区域的数据能尽快被转移到非拥塞区域。仿真结果表明,与其他算法相比,该算法能够提高分组成功递交率,降低端到端延时,提升网络的整体性能。 An enhanced congestion traffic allocation (ECOTA) and an efficient congestion detection and mitigation (ECODEM) algorithm are proposed in this paper, based on the traffic allocation and reallocation algorithm. After measuring the energy consumption and transmission delay of all paths, some low energy consumption and short delay paths are selected to increase the success rate of data transmission. The congested area is detected by methods of setting the threshold and prediction. Once the congestion occurs, nodes can quickly recover from congested situations by using reasonable traffic reallocation. And traffic in the congested area can be transferred to the non-congested area as soon as possible. Simulation results show that compared with other algorithms, the proposed algorithm can improve the success rate of packet delivery, reduce the end to end delay and improve the overall performance of the network.
