Abstract
Aiming at the lack of mutation mechanism and premature convergence of bat algorithm
an improved bat algorithm is proposed. For the premature convergence problem
the inertia weight is introduced to balance the exploration and exploitation of the algorithm; and for the lack of mutation mechanism
a random direction factor is introduced to enhance the diversity of the population. In the application of wireless sensor networks(WSNs)localization
the localization problem is transformed into a global optimization problem
and the improved algorithm is used for localization optimization. Simulation experiment show that the proposed algorithm has high localization precision.
