Adaptive Particle Swarm Optimization based QoS Aware Scheduling Routing Protocol (APSO-QSRP) for Heterogeneous Mobile Ad hoc Networks

摘要

Ensuring quality of service (QoS) is one among the plunge research topic for mobile ad hoc networks. This research work aims to propose an adaptive particle swarm optimization approach in order to provide quality of service aware scheduling routing protocol for heterogeneous mobile ad hoc networks. The proposed routing mechanism involves broadcasting. Two major parameters are estimated namely received signal strength and queuing delay. Once after estimating the parameters, adaptive particle swarm optimization algorithm is incorporated for optimized routing performance. The fitness function of the particle swarm optimization utilizes parameters received signal strength and queuing delay. Packet resizing mechanism is utilized. The proposed protocol has been tested on NS-2 using the performance metrics such as throughput, packet delivery ratio, overhead, packets drop and delay. The simulation has been carried out based on mobility speed and pausetime. Mobility speed is taken for ensuring the proposed protocol's performance on heterogeneous environment where the nodes may move at different speed that ranges from 0.5 to 2.5 meter per second. Extensive simulation results emphasizes that the proposed routing protocol (APSO-QSRP) achieves remarkable QoS in terms of throughput, packet delivery ratio, overhead, packets drop and delay based on both pausetime and mobility speed.
