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 speed, packet size, average connection arrival rate, number of nodes, grid size and packet inter-arrival time.
