the SUM/MIN energy algorithm in all cases considered. It seems that the 0.5 exponent on the
number of hops in the former algorithms effectively eliminates the impact of the hop term on
the cost function. is is the reason we chose not to present in great detail the results on the SUM/
MIN energy–half-hop algorithm.
Figure 8.4d shows the received-to-sent packets ratio for various algorithms examined. When
the initial energy of the nodes is infinite, all the packets are delivered to their destinations, but
when the initial energy is finite, the fraction of packets delivered to their ...
