A mobile ad hoc network is a special kind of wireless mobile communication network, featuring equal status of all terminals, ad hoc, no need for prior arrangement of any network facilities or central control nodes, dynamically changing topology and bandwidth and energy restriction. In recent years, research on mobile ad hoc networks, especially research on media access control and routing protocols have research focus. In this paper, the well-known on-demand routing protocol AODV is analyzed and is improved as AODV-CLMP, with a simulation platform used to evaluate its performance, with some meaningful conclusions drawn. In this paper, the origin, characteristics, application and current development of mobile ad hoc networks are introduced briefly, followed by research on two kinds of well-known on-demand routing protocols for mobile ad hoc networks, i.e. AODV and AODV-CLMP. Finally, commonly used network simulation software is compared to conduct evaluation and analysis of the performance of the AODV and AODV-CLMP protocols. Through the analysis of the simulation result of such evaluation indicators as average end-to-end delay, packet delivery fraction and throughput, the following conclusions are drawn: the average delay, packet deliveryfractionand throughput of AODV-CLMP protocol are superior to those ofAODV protocol, indicating thatAODV-CLMP protocol can transmit information more rapidly and steadily.
