Tight Analysis of Shortest Path Convergecast in Wireless Sensor Networks

The authors consider the convergecast problem in wireless sensor networks where readings generated by each sensor node are to reach the sink. Since a sensor reading can usually be encoded in a few bytes, more than one reading can readily fit into a standard transmission packet. They assume that any such packet consumes one unit of energy every time it hops from a node to a neighbor regardless of the total size of the readings in it.
