QoS Improvement in MANET Using Particle Swarm Optimization Algorithm

MANET is the type of communication network in which communicating device can move anywhere. Movability of devices plays a key role when we discussed about the performance of any routing protocol used in MANET. Performance of any MANET routing protocol depends on the values of its parameters. What will be the value of these parameters for which the performance of protocol is optimal? In this work the particle swarm optimization technique is used to select the optimal value of parameters of AODV routing protocol to improve the QoS in MANET. Java programming language is used to implement optimization technique and then output value is used as input into the network simulator tool NS2.35 for majoring the performance of AODV. The experimental results show 70.61 % drop in Average End-to-End delay (AE2ED), 34.06 % drop in Network Routing Load (NRL), and slight improvement (1.81 %) in Packet Delivery Ratio (PDR) using optimal combination of value of parameters.
