The Application Of Self Organizing Wireless Network In The Fields Of Real-time Information Transmission

Self organizing wireless network is a group of autonomous wireless terminal to cooperate with each other and form independent of fixed infrastructure and the use of distributed management network. It adopts the multi-hop, no base facilities and strong expansibility characteristic with respect to traditional agricultural information wireless transmission mode, and can satisfy the precision agriculture on field information real-time transmission and accuracy requirements.and has become the hot spot of agriculture.Analysis The deficiency of the traditional wireless network transmission way in farmland real-time information transmission. Research of wireless self-organizing network topological structure. Comparison of five kinds of advantages and disadvantages of network simulation software. Combined with the farmland information real-time transmission requirements, study and compare in wireless self-organizing network AODV protocol, DSR protocol, DSDV protocol three typical routing protocols of information transmission in neutral can show, find the most suitable routing protocol, for wireless self-organization network in precision agriculture to provide reference information for the application.Compared the performance of AODV protocol, DSR protocol, DSDV in different node movement speed and different node density respectively, through the packet delivery success rate, end-to-end delay, to the target node by hop as three parameters on its performance were assessed, on-demand routing protocols for AODV and DSR packet delivery success rate slightly higher than the table driven routing protocol DSDV, but the other two parameters are relatively good performance of DSDV protocol. Integrated network simulation results and field information transmission request, showed that the table driven routing protocol DSDV is more stable, more suitable for field information wireless transmission.
