There exists a trade-off of optimizing the average or maximum TTR in the CH rendezvous protocol design. On one hand, the random CH protocol leads to the best \"average\" TTR without ensuring a finite \"maximum\" TTR (two CRs may never rendezvous in the worst case), or a high rendezvous diversity (multiple rendezvous channels).
