Predictive Interference-Based Scheduling Mechanism for Direct Communications in IEEE 802.16 Networks
The Point-to-Multi-Point (PMP) mode is considered a well-adopted transmission type that is supported by the IEEE 802.16 standard. The Base Station (BS) is served as a centralized coordinator to control and forward packets for Mobile Stations (MSs) within the network. With the consideration of direct communications, the required bandwidth and packet latency are reduced. However, the inappropriate arrangements of direct communications may introduce additional inter-cell interferences for other communications. In order to avoid this situation, a Predictive Interference-based Scheduling (PIS) mechanism for each pair of MSs that are expected to conduct direct communication is proposed in this paper.
