Routing Optimization using Swarm Algorithm in Mobile Ad Hoc Networks

Abstract

Several advancements in Mobile Ad hoc Networks (MANET) due to the enormous utilization of mobile sensors in the market and it is the huge collection of nodes that can communicate directly or indirectly. Therefore, it grasps the attention of numerous researchers in the research field behalf of its dynamic nature of the network. There are several research issues and challenges in the MANET such as node mobility, optimization problem and network efficiency so on. Further than, all these challenges, optimal path finding is considered most crucial issue in MANET. Because of imbalanced path, fixing the consumption of energy is dramatically increased in MANET network for the reason of dynamic network mobility. During the process of communication between the source node and the destination node, Imbalance path fixing increases the network delay, reduces the packet delivery ratio, reduces the network throughput and increases the packet loss that leads to accept the overall Quality of Service (QoS) of the network. Captivating these challenges into account, these study work mainly concentrated on proposed a new protocol with successful optimal path finding with optimization model. This thesis proposed a new routing protocol for MANET namely Lion Optimization Routing protocol (LORP) which are mainly based on AODV protocol to generate the pride by gather all possible path by RREQ, and Lion Swarm Algorithm that is one among the set of bio-inspired algorithms which is used to find the best possible path for data transmission between the source and the destination. The general routing processes are Route Request, Route Reply, Error Finding, Hello Message processes are taken from ad-hoc on demand routing protocol, and mainly to find the best path, the Lion Optimization Algorithm is used. The optimization technique divided into two steps that are Maximization Algorithm and Minimization Algorithm. The major parameters that are used in Maximization Algorithm are Power Efficiency, Throughput, and Packet Delivery Ratio. The parameters that are used in Minimization Algorithm to select the best path are Delay and Short Path. The evaluation of the simulation is carried out in Network Simulation (NS2 -2.34) and it is discussed elaborately. In these study three scenarios have been used which are 25nodes, 50nodes and 100nodes. The performance of the proposed protocol is calculated and then compared with another VII protocols such as Ad hoc On Demand Vector Routing (AODV), Dynamic Source Routing (DSR) and AntHocNet. The parameters that are concentrated for comparison are packet delivery ratio, end-to-end delay, packet loss and network throughput. The gathered results show that the proposed protocol performs are better than another protocols in terms of packet delivery ratio , End-2-End delay and network throughput and it greatly helps to improve the overall QoS of the MANET network.
