Mobile ad-hoc networks are rapid deployable self organizing networks. Their key characteristics are dynamic topology, high node mobility, low channel bandwidth and limited battery power. Hence, it is necessary to minimize bandwidth and energy consumption. To transmit packets, available bandwidth is known along the route from sender to receiver. Thus, bandwidth estimation is the main metric to support Quality of Service (QoS). This paper focuses on improving the accuracy of available bandwidth and incorporating a QoS-aware scheme into the route discovery procedure. It is also important to limit the energy consumed by nodes. Probability based overhearing method is proposed to reduce energy spent on overhearing nodes.
