An analytical model to evaluate the non-saturated performance of the Distributed Queuing Medium Access Control Protocol for Ad Hoc Networks (DQMANs) in single-hop networks is presented in this paper. DQMAN is comprised of a spontaneous. temporary. and dynamic clustering mechanism integrated with a near-optimum distributed queuing Medium Access Control (MAC) protocol. https://allfixelectricales.shop/product-category/hose-end-coupling/
