摘要
拥塞问题导致6LoWPAN网络的数据包丢失,降低了网络吞吐量,并增加了额外能耗。为此,提出基于非协作博弈算法的能效拥塞(Non-cooperative Gaming for Energy-efficient Congestion Control,NGECC)策略。NGECC策略利用信道占用情况和缓存区的使用状况,优化叶节点的数据传输速率,进而避免父节点端的数据传输拥塞,从而降低数据包的丢失率。仿真结果表明,提出的NGECC策略提升了数据包传递率、吞吐量,并降低了能耗和数据传输时延。
Congest problems in 6LoWPAN cause significant packet loss that leads to degraded through put and extra energy consumption.Therefore,Non-cooperative Gaming algorithm for Energy-efficient Congestion Control(NGECC)is proposed in this paper.NGECC strategy uses channel occupation and useage conditions of cache area to the optimite data transfer rate of all leaf nodes to avoid data transmission congestion at the parent nodes so that the data packet losses can be reduced.The simulation results show that the proposed NGECC strategy improves the existing packet delivery ratio,throughput,and reduces energy consumption,and data transmission delay.
