QoS Routing for Wireless Mesh Networks Based on Ant Colony Algorithm

This paper proposes an Ant Colony algorithm based QoS Routing (ACQR) for wireless mesh networks,focusing on optimization problem regarding to multi-constrained QoS path selection.Using ant colony algorithm,this solution dynamically constructs path set that meets the requirements in end-to-end bandwidth,delay,packet loss rate and jitter,from which a node chooses a reasonable path according to predetermined fitness function.Our simulation results demonstrate that the proposed ACQR can reduce end-to-end delay and jitter,improve delivery ratio,and provide delay and reliability guarantees for data transmission.
