Abstract
Recently, Reguera et al. proposed a channel hopping scheme called short-sequence-based (SSB) rendezvous algorithm which works under symmetric and asymmetric channel models. After our revisit of the SSB implementation under the asymmetric model, we found that some cases will fail to have rendezvous in the asynchronous environment and the performance of SSB cannot be guaranteed as one would expect. In addition, we propose a conjecture for the failing cases.
