HAQR: The Hierarchical ANT Based QOS Aware On-Demand Routing for MANETS

A Mobile Ad Hoc Network (MANET) is a collection of wireless mobile devices with no pre existing infrastructure or centralized control. Supporting QoS during routing is a very challenging task. Clustering is an effective method for resource management regarding network performance, routing protocol design, QoS etc. In real time various types of nodes with different computing and transmission power, different rolls and different mobility pattern may exist. Hierarchical routing provides routing through this kind of heterogeneous nodes. In this paper, HAQR, 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.
