Packet collisions caused by the standard Distributed Coordination Function (DCF) protocol in wireless local area networks (WLANs) have been a challenging problem leading to congestion and reduced throughput.To solve this problem, we propose a novel backoff state generation algorithm, called adaptive virtual backoff algorithm (AVBA), operating in an

Malaria represents a major health problem in Yemen, and it appears that the efforts devoted to its control and elimination only tackle the tip of malaria iceberg.There is an evident gap between Testers research activities and control efforts reflected by the fact that efforts and funding allocation are mainly directed to control activities.Research
The U.S.Environmental Protection Agency (USEPA) provides databases that agglomerate data provided by companies or states reporting emissions, releases, wastes generated, and other activities to meet statutory requirements.These Saucepan Set databases, often referred to as inventories, can be used for a wide variety of environmental reporting and mo
The complex smear microbiota colonizing the surface of red-smear cheese fundamentally impacts the ripening process, appearance and shelf life of cheese.To decipher the prokaryotic composition of the cheese smear microbiome, the surface of a semi-hard surface ripened cheese was studied post-ripening by culture-based and culture-independent molecular
