Research ArticleOpen accessIn the abstractSSM: Slot Scheduling Mechanisms in a Multihop Wireless Hotspot NetworkMaan Younis AbdullahOur focus was to determine a "slot" time for message forwarding. To this end, we model the system as a "Queue" where the time for packet forwarding is determined by slot, at different slot range for each relaying node. We also introduced one important reason of the poor performance is the close coupling between medium contention and network congestion. Our … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,449 accessesView PDFCite
