Abstract :
We compare two multi-hop routing schemes: the first maximizes the minimum lifetime of the nodes; the second minimizes total energy consumption. We consider both the transmission energy and circuit energy spent in transmission, as well as the receiver energy. The comparison reveals that multihop routing is preferred by the first scheme when the ratio of transmission energy to circuit energy is low and by the second scheme when this ratio is high. In order to balance the load, the first scheme limits the range of multi-hop routing.
