The Multipath Protocol Study Of Ad Hoc Networks And The Ethernet Realization Of Modularized Inverters Communication

Modularization is a development direction of inverters design, the coordination works and control of many modular inverters is based on reliable data transmission. The task is the sub task of the inverters control and topology for a new high frequency and mini-type power by natural science fund (50237020), we focus on the networks communication of the modular inverters.This paper makes a primary study in achieving the communication among modular inverters by wireless network. It focuses on an in-depth study about the multipath protocol in Ad Hoc networks. On the performance analysis of the existing multipath routing protocol in Ad Hoc networks, in this paper, a new improved multipath protocol is presented to the On-demand Multipath Distance Vector Routing, which is based on the route reliability. The paper presents the measurement index of the route reliability. With the help of network simulating software, the performance of the protocol is analyzed. The paper also makes an experimental study of the communication among modular inverters by Ethernet. First, the interface circuit of the DSP LF2407A and RTL8019AS are designed. The Ethernet communication is realized partially via the software weaved. After that, the LF2407A is realized to connect into Ethernet by using ZNE-100T, and to communicate with the monitor computer in real time.Study results of multipath indicate that using route reliability as the backup path selection is validated with better protocol performance, and it could provide better support for mobile communications especially in fast movement environment. It also indicates that using Ethernet communication mode could realize the long-distance and real time communications of the monitoring computer and the modular inverters. It also could enhance thereliability and speed of data transmission.
