Abstract
A mobile Ad hoc Network (MANET) is a collection of mobile nodes (MNs) that cooperatively communicate with each other without any pre-established infrastructures. This paper proposes a new routing approach that combines the residual bandwidth, energy and mobility of the network nodes. The proposed composite metrics selects a more stable MPR set than the QOLSR algorithm. This proposed method also involves a bandwidth reservation model which ensures that the interferences produced by a new flow do not affect the bandwidth granted to the already accepted flows. Once the bandwidth is reserved, then the concept of admission control is introduced to tackle the problem of congestion in the network. By using mathematical analysis and simulations, this new approach is going to be used to calculate different QoS metrics such as routing load, packet delivery fraction, delay and bandwidth utilized by different number of flows.
