Ad hoc wireless networks are increasing in popularity because of the spread of laptops sensor devices personal digital assistants and other mobile electronic devices. These devices will eventually need to communicate with each other without an adequate infrastructure to rely on. For mobile ad hoc networks the complexity of routing increases because of its characteristics such as dynamic topology absence of centralized authority time varying quality of service QoS requirements etc. The biggest challenge in this kind of networks is to find a path between communication end points satisfying user s QoS requirement in spite of frequent path failures because of node mobility. Recent advances in wireless technology and availability of mobile computing devices with networking capabilities have generated a lot of interest in wireless ad hoc networks for QoS-based real-time multimedia applications. In this article we are proposing AMQR an ant-based multiobjective on demand QoS routing algorithm for mobile ad hoc network which will be highly adaptive efficient scalable and mainly reduces end-to-end delay in high mobility cases. Keywords MANET quality of service QoS routing ant colony optimization 1. Introduction Mobile Ad hoc NETwork MANET 1 is a collection of wireless mobile nodes which dynamically form a temporary network without using any existing network infrastructure or centralized administration .
