Research On Routing Technologies In Digital Radio Network

With the developing of scientific technology, the research on digital radio network is taking a progress. Digital radio network is a kind of wireless self-organization network, and it is widely used in the area of army. Since it is easy to use and the performance on signal is good, digital radio network is likely to be used in business area.In this thesis, the network protocol of digital radio is introduced and even the principle of designing the network protocol is analyzed. For further research, the routing protocol of digital radio network is studied and a classical routing protocol is improved.The innovative points in the thesis include:1. After the network protocol of digital radio is analyzed, the practical network can be simulated by the software.2. According to the shortcomings of AODV, an improved version is proposed and even realized. We name the new version protocol AMPR. It is the combination of AODV and Multi Point Relay.Finally, the performance of two routing protocol is compared on NS-2. The result is satisfying. The performance of AMPR is better.
