Abstract
Arrangements described herein provide a distributed means of scheduling communications directed towards a sink node from other nodes in a multi-hop wireless network. By listening for other messages assigning schedules to other nodes, each node is able to create its own local record of scheduled transmissions in its area. This allows each node to determine a preliminary schedule. Having said this, the parent node of the node will have additional information regarding the scheduled local transmissions. Accordingly, the node sends the preliminary schedule to its parent node for confirmation that it provides no collisions/conflicts with other scheduled transmissions. As the parent node is involved in the scheduling of each child node, it is better able to determine whether the child nodes are proposing schedules that may conflict with each other.
