In this paper, we firstly present an energy efficient (E2) and protocol independent mechanism for Mobile Ad-hoc Networks (MANETs) routing in disaster rescue operations. In such extreme emergency scenarios, protocols need to be energy efficient and scalable. We therefore proceed to integrate the E2 mechanism with the scalable ChaMeLeon (CML) protocol and consequently term it as E2CML. We support the E2 mechanism design using an energy consumption model for MANET nodes and use a packet delivery delay model to explain the scalability and energy efficiency of CML. Through the integration process of E2-CML, we primarily aim at satisfying the requirements for emergency MANETs (eMANETs), but also intend to demonstrate that the proposed mechanism is portable across popular protocols such as Optimized Link State Routing (OLSR) and Ad hoc On-Demand Vector (AODV). Finally, the paper presents simulation results to compare the improved routing performance of E2CML against both AODV and OLSR.
