(Based on the existing implementation scheme of NEMO (Network Mobility) network, a scheme based on forwarding mobile router is proposed In order to deeply study the mobile support ability of NEMO, the integrity of the network and the attributes of the FRM scheme, this paper expands the simulation computing ability of the NEMO network for the scheme of forwarding mobile routers on the platform of the NS 2 network simulator. This experiment uses a typical mobile network topology as the simulation computing scenario)
