Groundwave Modeling and Online Simulation System for Advanced HF Radio Networking
The aim of this project is to accomplish an online simulation system based on ns-2 open source network simulator to simulate advanced high frequency (HF) network. Given the location of a transmitter node and a receiver node, the online simulation system should be able to calculate the electric field strength and basic path loss. To simulate the HF radio network under real-word conditions, this online system must contain models of HF channel characteristics, waveforms, protocols and typical traffic loads. In this project, the online simulation system should ask for the configuration parameters of the transmitter and receiver radio station within an online Graphical User Interface (GUI), and brings back the result to the user. For the development of this project, it uses New Zealand conductivity database, a high-resolution elevation API (Google Map API). Also, to calculate the field strength and basic path loss due to ground wave propagation, this project choose to use ITU GRWAVE program.
