Mobile Ad hoc NETworks (MANET), which Comprise of mobile nodes connected wirelessly, are emerging as a very important technology for future generation of wireless mobile and ubiquitous computing. To support real-time communications (i.e., audio and video) over MANETs, Quality of Service (QoS) provisioning mechanisms need to be developed. QoS is usually defined as a set of service requirements that needs to be met by the network while transporting a packet stream from a source to its destination. The provision of QoS in wireless access networks is very challenging because of the movement of the hosts and the characteristics and unpredictable nature of wireless links.
