摘要 对于无线链路和共享信道的链路,由于受外界干扰或共享冲突的影响以及采取的应对措施,使得链路带宽处于变化中。这样的链路为不同用户所共享时,原有的分层链路共享方法由于假设带宽恒定,不能适用于这样的环境。通过对这一环境和链路共享机制深入分析,提出了适于带宽变化的链路共享方法,来满足用户对此链路带宽共享需求和服务质量需求,并通过大量仿真实验对这一方法进行了深入分析,验证了其可行性和合理性。 As far as wireless links and links sharing same communication channel are concerned, the bandwidth of them is in variation due to propagation impairments or collision among sharing entities and techniques to mitigate these side effects. When such a link is shared by multi-users, the previous hierarchical link-sharing techniques are not suitable for this condition since they are based on the precondition that the bandwidth is constant. With deeply analysis of this new condition and the mechanism of link-sharing, a method for link-sharing management for links with varying bandwidth was proposed. And a lot of simulation and analysis to this method were done and it is proved feasible and reasonable.
