MinEB: In a WANET, find a spanning tree rooted at the given source node such that the overall power consumption (OPC) is minimized.
An example: Let node s be the source and energy consumed for receiving each packet is 5 µJ for each node equally.
OPC(T1) = (8+0) + (10) + (7+5) + 5 = 35
OPC(T2) = (9) + (5) + (5) + (5) = 24
