Most existing MANET Proactive routing protocols rely heavily on hopcount evaluation. Although this is simple and efficient, it sacrificesthe potential performance gains obtainable by considering dynamicnetwork conditions such as congestion levels and link stability.Remedies of this issue have been presented by considering variouspredictive dynamic routing metrics mostly related to bandwidth andenergy consumption. However, those predictions do not fully appreciatethe nonstationary nature of the dynamic routing metrics and possibleheterogeneous power consumption of the nodes. With these addedconcerns, in this work, in-depth investigation is conducted onprediction and evaluation of dynamic routing metrics including queuingdelay, energy cost, and link stability. Artificial neural network modelsand advanced statistical methods are used for prediction of thesemetrics. Queuing delay and energy cost are investigated individuallyand then evaluated compositively together with predicted link stability. Their effects on multiple routingobjectives are extensively simulated and analyzed.
