The conventional Mobile Ad-hoc Network (MANET) is composed of mobile nodes without any infrastructure. But, emergent traffic such as disaster positioning by using wireless infrastructure is indeed required. Therefore, network deployment for ad-hoc would associate WiMax with WiFi which is called 802.16e MANET Environment in this paper. Based on the 802.16e MANET environment, we propose a novel Hierarchical Multicast Ad-hoc On-Demand Distance Vector Routing protocol (H-MAODV) for supporting multicast traffic rather than multiple unicast. The proposed H-MAODV scheme can avoid significant number of route discovery cost by using various bounded wireless coverage areas. On the other hand, Two-Points Positioning (TPP) for a paradigm of 802.16e MANET Environment is also proposed to solve the drawback of conventional triangulation method. Simulation results demonstrate that our proposed TPP outperforms conventional triangulation method. Moreover, by using proposed multicast service for H-MAODV applying in our deployed 802.16e MANET environment, emergent traffic for disaster positioning information would be delivered out immediately.
