In this experiment, the maximum residual energy in coalition is set to be
55000
mj
.When an coalition's residual energy is less than 5% of the maximum resi-
dual energy, namely residual energy is less than 2750
mj
, the network will be failure.
As shown in Fig.4, under different numbers of alliance, the batches of task executed
by NEPSO are the most. When the number of coalition is small, the disparity among
the three algorithms is not obvious, but with the increase of coalitions, it can obvious-
ly see that performance of NEPSO in improving the network life cycle is excellent,
RTAA and MCTTAA are much poor, especially MCTTAA.
