Mobile ad-hoc network (MANET) is an emerging domain among the
researchers, which is an ensemble scheme of numerous mobile nodes and it works
without any base station. In ad hoc networks, usage of energy is the main issue, and
the energy level of the node is not considered by Ad-hoc On-demand Distance Vector
(AODV) during the route discovery phase. The node with minimum energy in the
transmission area will fail transmission and packet dropping. The link failure reinitiates
the route request (RREQ) and consumption of energy also high. To enhance
this issue, an optimized routing strategy is introduced by the Ant Colony Optimization
with Bacterial Foraging Algorithm (ACO-BFA) for AODV. The routing process is
initiated by ACO and a high probability routing path is assigned to bacteria. The
routing is enhanced by the ACO-BFA technique and the simulation analysis shows
that the proposed technique outperforms the existing state-of-art AODV routing
techniques.

Due to decentralised architecture the nodes present in mobile ad-hoc networks nodes can able to move freely in the environment. Hence the nodes are characterised as self organised and self healing. Due to rapid movement of nodes link failures exists frequently between the nodes and if two nodes present in the range of communication, then the sensed data is passed directly to the sink node. To identify an efficient and concurrent bandwidth and trustable path between sending and receiving nodes; the communication link weight and node trust score factors are examined. The weight of the links is calculated by estimating longer link connectivity period and the bandwidth channel availability. Once the trust ratio for the nodes is evaluated through ratings then efficient bandwidth nodes are selected. Therefore the data is passed through the trusted node with high channel bandwidth towards the gateway.

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.

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.
