Research on improved INSIGNIA based on network measurement

Due to the difficulty of QOS assurance for MANET(Mobile Ad hoc Network) in which the network topology changes dynamically, we improve the INSIGNIA protocol and proposes a method based on network measurement to provide better QOS assurance. This paper introduces the design principle and implementation of this method in details, and then introduces the system model of this method which is designed and implemented in OPNET simulation environment, describes the experiment process of verifying the feasibility and effectivity of this system model through simulation result.
