A Novel ACSA Based Multipath QoS Routing Algorithms in ad hoc Networks
Feng Guang-zeng · Journal of Nanjing University of Posts and Telecommunications · 2008
ACSA-based routing protocols for ad hoc networks have been widely explored,but most of them are essentially single-path routing methods which have heavy burden on the hosts along the shortest path from source to destination.The robustness of these protocols is comparatively not good and is further weakened by the positive feedback mechanism of ants.Multi-path routing can support QoS better than single-path routing in ad hoc networks.We combine ACSA and link-disjoint multi-path routing to solve the problem mentioned above.A novel approach named ACSA-based Multi-path QoS-aware Routing (AMQR) is proposed.AMQR establishes and utilizes multiple routes of link-disjoint paths to send data packets concurrently and adopts pheromone to disperse communication traffic,thus it can adapt to the dynamic changes of the network and support QoS better.The simulation results show that the proposed approach outperforms other pertinent algorithms.
