Providing a convenient routing protocol for MANETs is a challenge because of the dynamic topology. Therefore, the suitability of each routing protocol depends on many parameters such as, network size, node mobility speed, andtraffic load. All that, together with the dynamic nature of MANETs, made an optimum routing protocol selection a complicated task. Extensive nodal mobility of MANETs makes multi-hop routinga genuine challenge. The frequent topology changes and variable propagation conditions make a routing table obsolete very quickly, whichresults in enormous control overhead for route...

Antibiotics resistance is one of the biggest challenges facing global public health. In the past sixty years, many classes of antibiotics have been developed, but duration of benefit appeared to be limited: resistance has emerged to every antibiotic class. Antibiotic resistance seriously hampers treatment of infections and leads to increased length of stay, morbidity, mortality and healthcare costs, both in hospital and community settings. In the era of increasing bacterial resistance and in the absence of new effective antibacterial drugs, it is necessary to use the currently available...
