Figure 3. Reliability: QBAR algorithm (solid line); AODV algorithm (dotted line)
QBAR balances node energy (e.g. between nodes
S i3, S i5, S i6 ) and reduces energy consumption by
switching the use of the sensor nodes. For instance,
considering a simulation over a time interval of
30 sec, the average and variance of energy con-
sumption are respectively of the order of 3·10 -4
Joule and 0.25·10 -4 Joule for the QBAR algorithm,
while they are of the order of 4·10 -4 Joule and
1.5·10 -4 Joule for the AODV algorithm. In this
way, all nodes have a resulting balanced energy
consumption with a reduction of node faults and
an increase in network life time.
Presence of Mobile Routers
Next, we have tried to validate the performance
of the proposed QBAR in the presence of a mo-
bile node. We consider the scenario in Figure 7a
