Abstract: -This paper proposes a new routing approach that combines the residual bandwidth, energy and mobility of the network nodes. Metrics are designed to cope with high mobility and poor residual energy resources in order to find optimal paths that guarantee QoS constraints. A maximizable routing metric theory has been used to find a metric that selects, during the routing process, routes that are more stable (less mobile), that offer a maximum throughput and that live for a long time. The OLSR (Optimized Link State Routing) protocol, which is an optimization of link state protocols designed for MANETs (Mobile Ad hoc Networks) is used as a test bed in this work. We prove that our proposed composite metrics selects a more stable MPR set than the QOLSR algorithm which is a well known QoS OLSR extension. By mathematical analysis and simulations, we have shown the efficiency of this new approach in terms of routing load, packet delivery fraction, delay and prolonging the network lifetime.
In paper REF proposed an approach for new routing which is combines energy, residual bandwidth, and mobility of new node.
