Abstract

A method determining scheduling for packet transmission in a convergecast network. The method includes receiving a request to perform an operation in the network. Initializing a query from the sink-node, the query is transmitted to a plurality of nodes, and in response to the query, the receiver receives information indicative at a period of time. Sorting the nodes by the sink-node based on the received information and using a sorting function that prioritizes each node to obtain a prioritized order of the nodes. Calculating an end-to-end delay for each node based on the time data by determining a difference between the data generation release time for each node and the data delivery time at the sink-node for each node. Scheduling packet transmission for each of the nodes based on a scheduling function having a set of predetermined scheduling criteria. Performing packet transmissions in the tree using the scheduled order.
