返回信息流仿真AODV,用14.5自带的模型,种子值设的不一样的话,仿真结果差别很大,看到有的论文上写,选取多个种子,结果取平均值,那么种子选取的原则是什么?
理论上,种子应该能随便选,而且网络稳定的话,仿真结果差别不会很大,但AD hoc网络拓扑是随机变化的,不知道大家有没有遇到这种情况?

Seed can affect the output psedo random numbers. So you'll get different random backoff timers, different traffic interarrival times, and other random values.
The value of the seed itself doesn't have any meaning. Each seed just represents one sequence of random numbers.Trying a few of them and taking the average value as the final output is a reasonable approach.
