ZOS:一种基于可用信道集的认知无线电快速重传算法
ZOS: A Fast Rendezvous Algorithm Based on Set of Available Channels for Cognitive Radios
摘要:
现有的交会算法大多是基于整个信道集来产生跳频序列。当可用信道的集合是整个信道集合的一个小子集时,它们是低效的。我们提出了一种新的算法称为ZOS,它使用三种类型的基本序列(即,零型,一型,S型)生成信道跳频序列的基础上的可用信道的集合。ZOS提供了保证的会合,没有任何额外的要求。ZOS的最大交会时间的上限为O(m1*m2*log2M),其中M是所有信道的数目,m1和m2是两个用户的可用信道的数目。
英文摘要:
Most of existing rendezvous algorithms generate channel-hopping sequences based on the whole channel set. They are inefficient when the set of available channels is a small subset of the whole channel set. We propose a new algorithm called ZOS which uses three types of elementary sequences (namely, Zero-type, One-type, and S-type) to generate channel-hopping sequences based on the set of available channels. ZOS provides guaranteed rendezvous without any additional requirements. The maximum time-to-rendezvous of ZOS is upper-bounded by O(m1*m2*log2M) where M is the number of all channels and m1 and m2 are the numbers of available channels of two users.
