Wireless networks and particularly ad hoc networks, are gaining in speed and capacity. These advances open the way to their use in emergent, increasingly complex applications. Such networks have to operate in disturbed environments where disturbances, mainly caused by fading and interferences, primarily originate by the physical layer. Congestions associated with environment-specific disturbances caused by complex applications, such as emergency and disaster applications, are the second source of disturbance. Such networks must guarantee a QoS (Quality of Service) management to their associated applications, a task that is possible only by minimizing the transmission delay and maximizing the packets delivery ratio.
