PPoL: A Periodic Channel Hopping Sequence with Nearly Full Rendezvous Diversity
share
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 a prime power, its period is N^2-N+1, and the number of distinct rendezvous channels of PPoL is at least N-2 for any nonzero clock drift. By channel remapping, we construct CH sequences with the maximum time-to-rendezvous (MTTR) bounded by N^2+3N+3 if the number of commonly available channels is at least two. This achieves a roughly 50 the state-of-the-art MTTR bound in the literature.
