We evaluate the protocols with both a scenario of dense network
and a randomly generated scenario of sparse network.
In addition, for the purpose of investigating the effect of overhearing,
we modifyed the energy model to allow the battery
power to be consumed by overhearing wireless channels.
We analyzed the time when each node die due to lack of remaining
battery (i.e., expiration time of nodes) as well as the
lifetime of connection which captures the effects of disconnections
due to lack of possible routes (i.e., expiration time of connections).
We also measured the average number of hops and
the average end-to-end delay per packet as well as throughput
calculated by the average total number of packets received by
the destination node. Specially, the end-to-end delay includes
the time spent in the queues for transmission at all nodes.
