It causes the primary interference(PI) or the secondary interference(SI). The minislot utilization will be decreased. In order to solve the above-mentioned problems, we proposed a pre-decided distributed scheduling scheme(PDS). And we also proposed a two-way handshake mechanism that is suitable for PDS. Finally, we proposed a mechanism to relay the schedule information. Let the nodes which are two-hop neighbors can receive the schedule information. After combining these three schemes, we can ensure to avoid PI and SI to achieve high minislot utilization. We compare our scheme and the IEEE 802.16 standard. The simulation results show our scheme improve the node throughput significantly. The average packet delay and fairness also better than IEEE 802.16 standard.
