Wireless Ad Hoc network is a need for fixed infrastructure, supported by a number of mobile nodes self-organizing wireless network. With traditional cellular communication system is the most important difference between the former does not require central control functional entity in the network there is no fixed base station and mobile switching center , so all agreements must be distributed work . Due to fast, flexible , easy to support user mobility and the ability to achieve the most extensive and complete sense of the continuous , seamless multimedia communications, personal communications and the Internet makes it a hotspot . For the current maritime mobile communication system , this paper first introduces the origins of wireless mobile ad hoc networks , features , applications and current developments. Then , this article from the wireless Ad Hoc network research in the field of research hotspot departure , were investigated multiple access techniques, different routing protocols performance analysis, efficient use of energy QoS routing protocol problem on this basis , for the first type should and two types of three reactive routing protocols (DSDV, DSR, AODV), on different network size , different simulation interval , different receiving power threshold , different mobile scenarios and different traffic scenarios in case the network simulation study complete end delay , packet arrival rate , routing overhead statistical analysis . The results show that the first routing protocol DSDV should end delay is relatively small, while reactive routing protocols DSR and AODV routing overhead packet arrival rate and the performance is relatively good. This innovation is the use of three kinds of simulation methods for wireless Ad Hoc network routing protocols , DSR (Dynamic Source Routing), SDV (Destination Sequenced Distance Vector) and AODV (Ad-hoc On demand Distance Vector) network performance and protocol overhead , giving network designers to provide a reference .
