For the applications’ needs of the future large-scale multimedia multicast system
consulting the service class of IEEE 802.16
proposal a novel service class with some restrict rules
then develop an energy efficient scheduling algorithm called VARTUL based on OFDMA
make best efforts to help mobile station prolong the time in sleep mode and reduce the times of mode switch.In this algorithm
unicast traffic coexist with multicast traffic
following the restrict rules and then users can subscribe the services freely
so VARTUL can support the system which merge broadcast services and data services into one platform to provide video
audio
data and other programs.Numerical results show that VARTUL is adaptive to meet the instance of uplink and downlink traffic ratio variety and random distributing of service traffic
and it can save energy significantly and guarantee the service combinations and service experience of every user.
