Mobility, energy limits and traffic congestion are the main reasons for a poor routing performance in MANETs. Inspired by those challenges, this paper proposes a new routing scheme named Mobility, Energy and Congestion Aware Routing (MECAR) to improve routing performance for MANETs. In this model, a node monitors the mobility, energy consumption and traffic congestion based on a multi-metric named AEC (constructed by Average Encounter Rate, Energy Consumption Rate, and Congestion Factor) to choose the most stable, power-rich and congestion-free path for routing. As a result, packet delivery ratio of the proposed model improves almost 20% compared to that of original AODV protocol while the number of dead nodes and routing overheads decreases significantly.
