Mobile Ad hoc NETwork (MANET) is network with different applications are developing with different service requirement. In particular multimedia applications and other real-time applications e.g. voice transmission. MANET is a autonomous network where communicating entities can communicate without the aid of any downlink power controller called base stations. Therefore, there is no centralized control over links. Further the link quality varies due to mobility of the nodes. Existing routing protocols like AODV or any other QoS routing does not account for changes in link quality once the path is established.
