Abstract

A new problem is addressed, which is how to improve energy efficiency for both unicast and multicast services without violating QoS requirements of mobile stations in 802.16e wireless networks. To solve this problem, a scheduling set based integrated scheduling (SSBIS) algorithm is proposed. SSBIS partitions all the mobile stations into multicast scheduling sets and a unicast scheduling set. All the unicast data of the mobile stations in the multicast scheduling sets are transmitted in the adjacent intervals of their multicast data transmission periods, and for the mobile stations in the unicast scheduling set, longest sleep duration based (LSDB) scheduling scheme is obtained using convex optimization to improve energy efficiency of the whole system. Numerical results show that SSBIS can save overall energy significantly and guarantee the minimum data rates of mobile stations at the same time.
