“…However, objective aimed at spatial reuse and concurrent transmission cannot achieve QoS requirement; furthermore, the efficiency of network cannot be guaranteed. We propose a throughput and efficiency optimization data subframe scheduling scheme in [20], named as TEOS, which improves network performance greatly. Note that it assumes all connections have same kind of flows in the network, without considering service differentiation for QoS guarantee.…”

WiMAX distributed scheduling can be modeled as two procedures: three-way handshaking procedure and data subframe scheduling procedure. Due to manipulating data transmission directly, data subframe scheduling has a closer relationship with user Quality of Service (QoS) satisfaction, and has more severe impact on network performance, compared with handshaking procedure. A QoS guaranteed Throughput-Efficiency Optimal distributed data subframe Scheduling scheme, named as QoS-TEOS, is proposed. QoS-TEOS achieves QoS guarantee through modeling services into different ranks and assigning them with corresponding priorities. A service with higher priority is scheduled ahead of that with lower priority and offered with high QoS quality. Same kinds of services that request similar QoS quality are classified into one service set. Different service sets are scheduled with different strategies. QoS-TEOS promotes network performance through improving network throughput and efficiency. Theoretical analysis shows that the scheduled data transmission should balance data generation rate from upper layer and transmission rate of physical layer, to avoid network throughput and efficiency declining. Simulation results show that QoS-TEOS works excellently to achieve throughput-efficiency optimization and guarantee a high QoS.

“…The choice of n is up to the specific MAA. At present, several algorithms have been designed from the perspective of Qos [5] [6], fairness [4] [5], throughput [4] [5] [7] and so on. In this paper, we use FEBA mentioned in [4] [5] as our MAA for its several strong points.…”

In WiMAX Mesh Networks, the waste problem of allocated minislots in the three-way handshaking procedure of Coordinated Distributed Scheduling (CDS) will degrade the endto-end performance of traffic flows. In this paper, an enhanced mechanism which combines adaptive holdoff algorithm with regrant solution is proposed to deal with the above-mentioned problem. Moreover, a new grant horizon based on the grant algorithm in Fair End-to-end Bandwidth Allocation (FEBA) algorithm is presented. Simulations using the network simulator NS-2 show that our enhanced mechanism can increase the endto-end throughput by 91% and decrease the average end-to-end delay by 25% when compared to the situation without considering minislot waste. In addition, this mechanism can extend the application area of original regrant solution by reducing the beginning point of grant horizon under a given network topology. Meanwhile, our proposed grant horizon outperforms two kinds of existing grant horizon when adaptive holdoff algorithm is used.

Backhaul network plays a significant role to interconnect access points and further connect them to gateway nodes. A failure sustainable wireless backhaul topology is proposed to ensure undisrupted telecommunication services even in the presence of occasional node or link failures. Furthermore, a new control message, called reverse notification, is proposed to improve the performance of coordinated distributed scheduling in the ladder topology. Computer simulation results show that the reverse notification scheme has improved the network throughput and reduced the packet transmission delay.
