Distributed hierarchical scheduling in an AD hoc network
摘要:
An ad hoc network with distributed hierarchical scheduling is disclosed. In one aspect, stations in a network mesh detect interfering neighbor stations and form interference lists. Stations transmit their interference lists. Scheduling stations schedule allocations for child stations in response to interference lists, received remote allocations, or a combination thereof. Coordination messages are transmitted including frame structure, allocations, and interference lists, among others. In another aspect, an ad hoc mesh network may be organized into a tree topology. In an example wireless backhaul network, this matches traffic flow. Distributed, hierarchical scheduling is provided where parents schedule communication with children while respecting already scheduled transmissions to/from interferers and to/from interferers of their respective children. Procedures to construct interference constraints for distributed, hierarchical scheduling are described, resulting in efficient scheduling and reuse in an ad hoc wireless network, without centralized scheduling. Various other aspects are also disclosed.
