A hybrid adaptive routing algorithm for mobile WiMAX using swarm intelligence

The paper presents the WiAntHocNet routing algorithm for mobile WiMAX, which combines ideas from Ant Colony Optimization (ACO) routing with techniques taken from more traditional routing algorithms. The algorithm has hybrid architecture, combining both reactive and proactive mechanisms based on the shortest path ant behavior. Here, we propose to study and compare the performance of the proposed routing protocol with AODV for Mobile WiMAX environment. Overall, the proposed algorithm shows high throughput, reduced end to end delay, and increased packet delivery ratio. Extensive simulations are conducted under OPNET simulator to evaluate the effectiveness of the proposed approach in both dynamic and static environments.
