Abstract:
The IEEE 802.16e standard introduced the concept of mobile subscriber stations (MSS) to provide mobility support. Five quality of service (QoS) classes have been defined to support QoS requirement different connections between the base station and the subscriber station. Out of these QoS classes, UGS has been designed to support real-time service flows that periodically generate fixed-size data packets. Most of the existing scheduling schemes for UGS class consider scheduling of a single MSS or even if they consider scheduling of multiple MSSs, the QoS requirement of the MSSs is not satisfied properly after scheduling. In this paper we have proposed a scheduling scheme, which schedules multiple MSSs with UGS connections so that QoS requirement of each MSS can be satisfied after scheduling.
