基于M／G／1排队模型的业务流性能研究
Study of Business Flow Performance Based on M/G/1 Queuing Model
摘要
Abstract
As wireless sensor networks may have congestion problem, a new performance characterization method was proposed which first used M/G/1 queuing model to establish one-step transition probability ma- trix and derived the mathematic formulas of queue length and delay time for business flow based on First Come First Served policy. A simulation was conducted to study the relationship between waiting time of the system and service rate as well as arrival rate when service source respectively obeyed fixed-length distribu- tion and k-Erlang distribution. The results show that waiting time has positive relationship with arrival rate and negative relationship with service rate and has much impact on k-Erlang distribution.关键词
