Ad Hoc Network Technology In Wireless Video Transmition System

In recent years, wireless communication is developing rapidly, currently there are a lot of wireless video transmission products on the market, but few of them can satisfy both the high-quality, long-distance video transmission and self-organizing network function. To resolve this contradiction, there is an urgent need to develop a new type of wireless video transmission system. This issue is raised in this context, the main task is to AdHoc ad hoc networks of our OFDM technology for wireless video transmission system.As a self-organizing network AdHoc study, one of the most important aspects, the wireless self-organizing network routing protocol has been widely appreciated. In this paper, a variety of self-organizing network routing protocol analysis and comparison, based on the AODV routing protocol is chosen as our realization of the object, through the linux firewall, network architecture, as well as implementation mechanism of the study, presents a netfilter framework in linux operating system, implemented on AODV protocol design, gives a detailed implementation process, in practice have proved such a program feasible.The paper's main work is reflected in the following aspects:1. A detailed study of the Adhoc Network characteristics and routing protocols, and conduct comparative analysis, from which select the AODV routing protocol as our goal.2. To elaborate on our research project on OFDM wireless video transmission system, system architecture, given the baseband and RF parts of some of the design, and the clarification of the Adhoc technology applications in our system for the enhancement of system functionality and the application prospect of.3. With ADHOC network characteristics as well as our demand for the wireless transmission system designed AODV protocol implementation software and hardware platform, and made a linux operating system, based on the netfilter architecture implemented on AODV protocol design, we achieved under this scheme AODV agreement and pass the test to verify the program put a reasonable and correct result.
