BaseStation Scheduler.
Definition: bs-scheduler.h:46
This class implements a simple downlink scheduler for rtPS flows.
bool SelectConnection(Ptr< WimaxConnection > &connection)
Selects a connection from the list of connections having packets to be sent .
void BSSchedulerPrimaryConnection(uint32_t &availableSymbols)
schedules the primary connection
void Schedule(void)
Schedule function.
std::list< std::pair< OfdmDlMapIe *, Ptr< PacketBurst > > > * GetDownlinkBursts(void) const
This function returns all the downlink bursts scheduled for the next downlink sub-frame.
bool SelectRTPSConnection(Ptr< WimaxConnection > &connection)
Check for rtPS connections that have packets to transmit.
Ptr< PacketBurst > CreateUgsBurst(ServiceFlow *serviceFlow, WimaxPhy::ModulationType modulationType, uint32_t availableSymbols)
Creates a downlink UGS burst.
void BSSchedulerUGSConnection(uint32_t &availableSymbols)
schedules the UGS connection
void BSSchedulerBEConnection(uint32_t &availableSymbols)
schedules the BE connection
bool SelectNRTPSConnection(Ptr< WimaxConnection > &connection)
Check for nrtPS connections that have packets to transmit.
void BSSchedulerBasicConnection(uint32_t &availableSymbols)
schedules the basic connections
bool SelectMenagementConnection(Ptr< WimaxConnection > &connection)
Check for Basic and Primary connections that have packets to transmit.
void BSSchedulerInitialRangingConnection(uint32_t &availableSymbols)
schedules the IR connections
void AddDownlinkBurst(Ptr< const WimaxConnection > connection, uint8_t diuc, WimaxPhy::ModulationType modulationType, Ptr< PacketBurst > burst)
This function adds a downlink burst to the list of downlink bursts scheduled for the next downlink su...
bool SelectUGSConnection(Ptr< WimaxConnection > &connection)
Check for UGS connections that have packets to transmit.
void BSSchedulerRTPSConnection(uint32_t &availableSymbols)
Downlink Scheduler for rtPS connections.
void BSSchedulerBroadcastConnection(uint32_t &availableSymbols)
