MANET is a collection of mobile devices with no centralized control and no pre-existing infrastructures.
Due to the nodal mobility, supporting QoS during routing in this type of networks is a very challenging
task. To tackle this type of overhead many routing algorithms with clustering approach have been
proposed. Clustering is an effective method for resource management regarding network performance,
routing protocol design, QoS etc. Most of the flat network architecture contains homogeneous capacity of
nodes but in real time nodes are with heterogeneous capacity and transmission power. Hierarchical
routing provides routing through this kind of heterogeneous nodes. Here, routes can be recorded
hierarchically, across clusters to increase routing flexibility. Besides this, it increases scalability and
robustness of routes. In this paper, a novel ant based QoS aware routing is proposed on a three level
hierarchical cluster based topology in MANET which will be more scalable and efficient compared to flat
architecture and will give better throughput.
