Wireless sensor networks (WSNs) are increasingly gaining popularity, especially with the advent of many artificial intelligence (AI) driven applications and expert systems. Such require specific relevant sensors’ data to be stored, processed, analyzed, input Obviously, nodes (SNs) have limited energy computation capabilities normally deployed remotely over an area interest (AoI). Therefore, proposing efficient protocols for sensing sending is paramount WSNs operation. Nodes’ clustering a widely used technique in WSNs, where grouped into clusters. Each cluster has head (CH) that gather captured forward it remote sink node further processing decision-making. In this paper, optimization algorithm adjusting CH location respect within proposed. This aims at finding optimal minimizes total sum nodes’ path-loss incurred intra-cluster communication links between CH. Once identified, moves location. suggestion re-positioning frequently repeated new geometric position. Excitingly, extended consider inter-cluster belonging different clusters distributed spiral trajectory. These form multi-hop link convey clusters’ destination node. The performance proposed positioning single multi-clusters been evaluated compared other related studies. results showed effectiveness algorithm.
