Abstract:

In this paper,the wireless ad hoc network is used to achieve distribution network fault detection.Real-time online monitoring of the distribution network is achieved by installing wireless nodes to distribution networks.This paper simulated protocol of wireless ad hoc networks using the NS2 software to select the protocol for this system to improve system performance.A Comparison is made between end-to-end delay and packet delivery ratio under different number of nodes and the residence time of three protocols,namely DSDV,DSR,and AODV.Their throughputs under the basic access mechanism and RTS/CTS mechanism are also compared.Finally,the AODV protocol is chosen and the frame size threshold is set.
