The occurrence of the hidden node problem in IEEE802.11ah has increases by 41% as compared to previous versions of IEEE802.11 standards. This makes IEEE802.11ah network to be prone to experience high collision and low throughput. Previous efforts to solve this problem has mainly not addressed the issue of locating potential hidden nodes in the network. As a result, the hidden node problem in IEEE802.11ah still remains an open issue. This paper proposes an algorithm that applies bat algorithm for detecting hidden nodes in IEEE802.11ah networks. Our results have shown the effectiveness of this algorithm in detecting hidden nodes. This algorithm can be used to properly manage communication in IEEE802.11ah.
