Abstract
A mobile ad hoc network (MANET) involves a group of wireless mobile nodes which create an impermanent network with no central authority and infrastructure. The nodes in the MANET are highly mobile and it results in adequate network topology, link loss, and increase the re-initialization of the route discovery process. Route planning in MANET is a multi-hop communication process due to the restricted transmission range of the nodes. Location aided routing (LAR) is one of the effective routing protocols in MANET which suffers from the issue of high energy consumption. Though few research works have focused on resolving energy consumption problem in LAR, energy efficiency still remains a major design issue. In this aspect, this study introduces an energy aware metaheuristic optimization with LAR (EAMO-LAR) protocol for MANETs. The EAMO-LAR protocol makes use of manta ray foraging optimization algorithm (MRFO) to help the searching process for the individual solution to be passed to the LAR protocol. The fitness value of the created solutions is determined next to pass the solutions to the objective function. The MRFO algorithm is incorporated into the LAR protocol in the EAMO-LAR protocol to reduce the desired energy utilization. To ensure the improved routing efficiency of the proposed EAMO-LAR protocol, a series of simulations take place. The resultant experimental values pointed out the supreme outcome of the EAMO-LAR protocol over the recently compared methods. The resultant values demonstrated that the EAMO-LAR protocol has accomplished effectual results over the other existing techniques.

Summary
An adhoc network belongs to a single session connection which doesn’t utilize wireless routers/base stations and mainly it is made for transitory network connection. The node has constrained computation ability capable of transmitting the data packet from source to the essential destination These types of networks are suitable for distinct applications including emergency situations, outdoor activities, certain military operations, natural calamities, and communication in place with no wireless services. The key challenge in MANETs is the development of dynamic routing protocol which could be aware of mobility and effective for determining the routes among the transmitting nodes with less overhead and better performance [4]. Location Aided Routing (LAR) protocols are a methodology which reduces overhead of route discovery with the help of Position details of mobile host. These position details might be attained by the global positioning system (GPS) [6].
