A Novel Protocol of QoS Multicasting for Large Scale MANET

QoS-enabled multicast protocol for Mobile Ad-hoc Network (MANET) has recently drawn attention from researchers because of its potential and broad applications in various fields. It is challenging to design a multicast protocol which meets Quality of Service (QoS) requirement when the bandwidth availability is very limited, e.g. military wireless communication network. Other constrains may include stringent real-time requirement, robustness and harsh environment etc. In this paper, we propose an Integrated Services (IntServ) bandwidth-based multicast routing protocol, named Hybrid QoS Multicast Routing Protocol (HQMRP), which combines reactive and proactive schemes to build source-based trees, and performs route maintenance to accommodate the ad-hoc environment. Different design choices have been investigated through intensive simulation work in order to find their most suitable working scenarios.
