ACO–EEOLSR: enhanced energy model based link stability routing protocol in mobile ad hoc networks

A mobile ad hoc network (MANET) has abundant mobile nodes that are free to
communicate independently in many locations. Many existing energy models address
the inadequacy of resources based on Ad hoc On-demand Multipath Distance Vector
and Optimized Link State Protocol (OLSP) routing protocols for MANET along with
various parameters. The architecture of energy-efficient routing mechanisms is a
challenging problem in a MANET. In this work, a novel energy-aware routing model is
introduced for MANET comprising an ant colony optimization (ACO) enhanced
approach to energy-efficient-optimized link state routing (named ACO–EEOLSR).
Initially, the route discovery is progressed by means of neighbor estimation and also
with the authentication of link stability. Parameters such as energy, distance, and hop
count are employed as willingness nodes, where both the energy and distance are
entrenched through the OLSP. Consequently, the hop count is applied via the ACO
system that is beneficial for link stability. After the acceptance of an acknowledgement,
the hop count is authorized for further performance analysis. This approach increases
the Quality of Service and also uses less energy compared to other energy models. The
accomplished simulation upshot depicts that the ACO–EEOLSR outperforms the
EEOLSR scheme with respect to the performance metrics of energy consumption,
packet delivery ratio, total remaining time, average network lifetime, and a variance of
energy.
