IEEE 802.16 Standard leaves the minislot allocation in mesh mode for further study. The minislot is the basic unit for resource allocation. The simple minislot allocation scheme (SMAS) is proposed to allocate minislots according to the request from the requester node. However, SMAS is an inflexible scheme, because it can not adjust the request according to available minislots. We proposed a dynamic minislot allocation scheme (DMAS) to improve the flexibility of SMAS with minimum change in MSH-DSCH request IE field. The DMAS adjusts the Demand Persistence specified in MSDH-DSCH request IE to reduce the end-to-end delay, and get better throughput compared to SMAS. This paper introduces a new minislot allocation scheme (i.e. DMAS) and discusses the simulation results.
