         10.   CONCLUSION                                      slicing from these perspectives.
         In this paper, we have addressed the resource allocation
         problem  in  an  M‑TTSD  network.   We  have  proposed
         a  multi‑tier  multi‑domain  slice  user  matching  game
         and  also  a  distributed  backtracking  multiplayer  multi‑
         domain game scheme to facilitate a business‑to‑business
         resource transaction framework and to ensure maximum
         network utility.  The maximum utility optimisation prob‑
         lem was transformed via the hierarchical decomposition
         method.   The  slice  users  were  associated  with  access
         points  in  the  respective  tiers  of  the  different  domains
         by  the  concept  of  the  multi‑tier  multi‑domain  matching
         game,  and  then  network players bid  for resources from
         higher hierarchical players via the concept of distributed
         multiplayer backtracking.
