摘要: 随着社会科学的发展,传统网络服务模式已经被普适计算的新型模式所代替,并随之出现了各种终端设备并存的网络局面,在网络服务的任务迁移中,不可必免地产生拥塞,其直接影响了网络的传输性能。针对当前传统的Red算法在拥塞问题中的不足等问题,设计了一种新的I}AR}d拥塞控制算法,通过NS2的实验仿真表明,该算法在普适计算环境中表现出极好的性能,能有效地避免拥塞,满足了普适服务的要求。

Abstract: With the development of social science, the traditional network services model has been replaced by a new model called for pervasive computing model. And then the coexistence of a variety of terminal equipments network situanon comes up. When the task is in the migration of network services,the generation of congestion is inevitable. The result is that congestion has a direct impact on the transmission performance of networks. For the problems of the current traditional algorithm,for example congestion problems,a new congestion control algorithm DARed was designed. that the algorithm in ubiquitous computing environment has shown excellent performance is shown by NS2 simulation experimenu. It can be effective for avoiding for network congestion, and meet the universal service requirements.
