The evolution of wireless technologies has led to the need to provide network support for data and video applications and thus foster the development of new types of network configurations. MANET is an important type of network operation that employs mechanisms that can enable a dynamic self-configuration to challenge the routing protocols. These protocols can also be challenged because energy failures are becoming more serious than the common network failures; in addition, the quality of the multimedia stream corresponds to a type of data flow that is increasingly prevalent in today's network. In light of this, a new cross-layer routing mechanism is set out to make an improvement in the main routing protocols. This involves adding decision metrics to all the network layers in a fuzzy-based mechanism with QoS and QoE guarantees, mobility indexes and energy parameters, by choosing the best path with an efficient way to use energy. The proposal has been evaluated in a network simulator which demonstrates the efficiency of increasing energy awareness and maximizing the life time of the network.
