摘要

我们提出并比较了三种固定信道分配的信道恢复方案。在方案I中，故障通道在可用时由空闲通道切换。在方案II中，只有在尝试在短时间内恢复故障通道失败后才采用交换策略。方案III是方案I和方案II的混合方案:对于一些不合格的渠道，采用方案I;其余的则采用方案II。为了真实地反映交通模式，采用不动点迭代方法捕捉切换到达的动态行为。针对这三种方案的可执行性分析，建立了随机奖励网(SRNs)。

Performability analysis of channel allocation with channel recovery strategy in cellular networks

We propose and compare three channel recovery schemes for fixed channel assignment. In Scheme I, a failed channel is switched by an idle channel whenever it is available. In Scheme II, the switching strategy is employed only after an attempt to restore the failed channel within a short period of time is unsuccessful. Scheme III is a hybrid of Schemes I and II: for some of the failed channels, Scheme I is applied; for the others, Scheme II is used. To reflect the traffic pattern in a realistic way, a fixed point iteration scheme is applied to capture the dynamic behavior of the handoff arrivals. Stochastic reward nets (SRNs) are developed for the performability analysis of the three schemes.
