Background: Mobile Ad hoc Network (MANET) has its application in tough terrains such as battle fields, disaster recovery, emergency rescue operations etc. The usage of MANET in these areas are very critical for communication. Energy is an important criterion in MANET for the successful communication of nodes without a link failure. The most of the mobile nodes are powered by battery. The nodes does routing which transfers the packets from source to destination. The consumption of energy by routing nodes arises the need for energy aware routing. Methods: In this work, an energy efficient LANDMARK selection process for E-LANMAR routing protocol in group mobility for a moderate networks size is proposed. In the proposed work, energy efficiency of a header node (LANDMARK) can be achieved by minimizing the frequent header selection process. This work is modelled and simulated in QUALNET 5.0.2 Simulator. The LANDNARK acts as a cluster head, the cluster head selection is based not only on the number of neighbours but also residual energy of a node. Results: The results shows that throughput and Packet Delivery Ratio (PDR) for E-LANMAR is better compared with LANMAR routing protocol. The reduction of frequent LANDMARK selection process in E-LANMAR routing protocol reduces the energy consumption of nodes further in group mobility. Application: The proposed work can be applied wherever the nodes in MANET moves in a group such as an emergency rescue operations, army battle field communication etc.
