In despite of the geographical location, internet connection is provided always and everywhere with the implications of designing of Mobile ad hoc network (MANET). Different types of applications of MANETs are included environment monitoring, military and disaster recovery. The resource-constrained environment of MANET is not allowed to perform the communication processes easily. For the network nodes, the limited batteries are utilized as an equipment. Throughout this process, the major challenging issue is replacing and recharging of these batteries. Within the MANET, the nodes are added without considering the circumstances. To process the communication among nodes, the trustworthy and reliable techniques should be inculcated. The definition of trustworthiness is about the opinion of a node on the other node with the numerical representation. The trust is computed based on the previous communication among current nodes. To address the limitations, a technique of modified multipath routing is needed. By using the network layer, efficiency is achieved in terms of energy utilization as the MANET is an infrastructure-less network and a peer-to-peer network. The routing path is chosen according to the network nodes’ current residual condition with the improved modified multipath routing protocol. The proposed technique is performed efficiently in terms of network stability and network’s lifetime than the existing methods like MRPC and E-AODV. To determine the proposed method’s effectiveness, NS2 software is utilized to assess the simulation results.

An infrastructure built in the Manet platform which is reliable to challenge the IT development communities of data stream in high dimensional data cluster modeling. This paper is based on reducing energy consumption and packet loss that leads to congestion control using random early detection (RED) and advanced load balancing in MANETs. Thus, this paper introduces an efficient routing technique called advanced load balancing Multipath routing using AOMDV protocol with fractional order particle swarm optimization (MRFPSO) in MANETs to efficiently balance the load among multiple path by reducing congestion using random early detection. This paper introduces a congestion control mechanism and an advanced load balancing mechanism during the data transmission process. The advanced load balancing mechanism is the selection of a gateway node by using link cost and the path cost to efficiently distribute the load by selecting the most desirable paths. The parameters in this paper in terms of control overhead, packet delivery ratio, average delay and packet drop ratio are found.

During the process of discovering route in MANET, path request broadcast and path response packets
are the necessary operations to locate the consistent route from the cradle point or node to the end node.
In these situations, intermediate node which may or may not belong to the route discovery process will
also update the route table and re-broadcast the route discovery packets to its neighboring nodes. Finally
the best possible path is found which has a minimum of hopping to reach the destination. This will
increase overhead and worsens routing performance in turn. The proposed Enhanced Petal Ant Routing
(The EPR) algorithm offers low overhead by optimizing FANT and BANT transmissions in the route
discovery process. This is a improvement from SARA and has features taken from petal routing. The
algorithm is simulated on NS2, against the ACO framework called SARA and classic routing protocols
such as AOMDV and AODV. The simulation results shows that EPR further reduces overhead by
eliminating redundant forwarding FANT compared to other routing algorithms.
