AN ANALYSIS OF ENERGY MODELS FOR MOBILE AD HOC NETWORKS

Energy must be significantly conserved in Mobile Ad hoc Networks (MANETs) by employing energy
models. Majority of the energy models address only the hidden terminal issue, but result in higher power
consumption due to increased collisions during packet transfer. The proposed energy model for MANET
involves an Energy-efficient Optimized Link State Routing (EE-OLSR) protocol and a path maintenance
scheme. The EE-OLSR energy model is based on a progressive search for the most energy-efficient path.
This model reduces the routing overhead and path setup delay, and enhances the network lifetime. The
existing energy models for MANET are based on OLSR protocol and DE (Differential Evolution) – OLSR
protocol with features like QoS (Quality of Service) optimization, accuracy of energy states, distributed
clustering, and energy-efficient clustering. The survey analysis involves the comparison of the proposed
EE-OLSR model with the existing energy models. The EE-OLSR model consumes lesser energy compared
to the existing energy models, with respect to nodal spe
