Energy Efficient Clustering in Wireless Sensor Networks via Bat Algorithm

What is it about?

Wireless sensor networks belong to the group of technologies that enabled emerging and fast developing of other novel technologies such as cloud computing, environmental and air pollution monitoring, and health applications. One important challenge that must be solved for any wireless sensor network is energy-efficient clustering, that is categorized as NP-hard problem. This led to a great number of novel clustering algorithms, that emerged with sole purpose to establish the proper balance in energy consumption between the sensors, and to enhance the efficiency and lifetime of the network itself. In this manuscript, a modified version of the bat algorithm, that belongs to a group of nature-inspired swarm intelligence metaheuristics, is proposed. Devised algorithm was utilized to tackle the energy-efficient clustering problems. Performance of proposed improved bat metaheuristics has been validated by conducting a comparative analysis with its original version, and also with other metaheuristics approaches that were tested for the same problem. Obtained results from conducted experiments suggest that the proposed method’s performance is superior, and that it could bring valuable results in the other domains of use as well.
