Abstract
A method includes identifying, at a first wireless node, routing costs associated with routing data to a destination through multiple paths in a wireless network. The method also includes identifying, at the first wireless node, information propagation values associated with the first wireless node and at least one second wireless node. The information propagation values are based on the routing costs and wireless link qualities associated with the wireless nodes. The method further includes scheduling transmission of the data by the first wireless node based on the information propagation values and transmitting the data based on the scheduling. The routing costs may include potential values associated with distances of the wireless nodes from the destination. Also, the information propagation values indicate which of the wireless nodes have a greater chance of propagating the data towards the destination in a single broadcast.
