Link transmission scheduling method and apparatus for coping with traffic changes in a wireless mesh network

摘要

The invention includes a method and apparatus for generating a link transmission schedule for handling traffic variation in wireless networks without dynamic scheduling or routing. The method includes determining fixed traffic capacities associated with respective wireless links of a wireless network according to a routing algorithm, and generating, using the routing algorithm and the fixed traffic capacities, a link transmission schedule including at least one condition by which traffic is transmitted using each of the network links. The link transmission schedule is adapted to remain substantially fixed during dynamic traffic changes. The routing algorithm may be a two-phase routing algorithm in which traffic is distributed by each node in the wireless network to every node in the wireless network using traffic split ratios. For two-phase routing, fixed traffic capacities may be determined using ingress and egress traffic capacities and traffic split ratios associated with respective nodes in the wireless network.
