A Randomized Learning Scheduling Scheme for TDD-based Wireless Mesh Networks

摘要

Time division duplex based wireless mesh networks (TDD-based WMNs) have emerged as a crucial technology for wireless multihop networks and broadband wireless access (BWA). The resource management in TDD-based WMNs is important to the network performance and one of the main challenges is to provide an efficient distributed scheduling to achieve robust communication for all nodes. In this paper, a randomized learning scheduling scheme is proposed for TDD-based WMNs. The scheme is a random selection scheduling based on information learning. In each multi-frame, the node decides the available slots according to the slots information learning from its neighbor and selects a control slot from its available slots to transmit scheduling message. Numerical results show that the proposed scheduling scheme achieves lower collision probability than the scheme presented in IEEE 802.16 standard.
