Load Balancing for Zone Routing Protocol to Support QoS in Ad Hoc Network

Application Routing Load Balancing (ARLB) is the novel load balancing mode that combines QoS routing and load balancing in per application for support QoS for real-time application based on wired network. Zone Routing Protocol (ZRP) is a recent hybrid proactive/reactive routing approach in an attempt to achieve scalability of ad-hoc network. This routing approach has the potential to be efficient in the generation of control traffic than traditional routing schemes. Up to now, without proper load balancing tools, the ZRP can actually guarantee QoS for delay-sensitive applications when congestion occurred in ad-hoc network. In this paper, we propose the ARLB to improve QoS for delay-time sensitive based on ZRP in ad-hoc network when congestion occurred and to be forwarding mechanism for route coupling to support QoS for real-time applications. The critical point is that the routing metric of ARLB is originally designed for wired network environment. Therefore, we study and present an appropriate metric or cost computation routing of ARLB for recently proposed ZRP over ad-hoc network environment.
