PPoL: A Periodic Channel Hopping Sequence with Nearly Full Rendezvous Diversity

Yi-Jheng Lin, Cheng-Shang Chang

We propose a periodic channel hopping (CH) sequence, called PPoL (Packing the Pencil of Lines in a finite projective plane), for the multichannel rendezvous problem. When $N - 1$ is…

On the Theoretical Gap of Channel Hopping Sequences with Maximum Rendezvous Diversity in the Multichannel Rendezvous Problem

Cheng-Shang Chang, Jang-Ping Sheu, Yi-Jheng Lin

In the literature, there are several well-known periodic channel hopping (CH) sequences that can achieve maximum rendezvous diversity in a cognitive radio network (CRN). For a CRN…
