Abstract
A network can include a number of nodes that link a source node to a sink node. When a first node in a network sends a packet to its downstream node, this information is also received at its upstream node. In response to learning that the first node has sent a packet, the upstream node sends another packet to the first node. In essence, a pull-based transmission approach is used to mitigate congestion and address the funneling effect in data transmission networks such as wireless video sensor networks.
