Tactical Ad Hoc Network Routing Protocols Amphibious Environment

Tactical Ad hoc is a mobile Ad hoc network which is used for tactical communication environment,It has a broad prospect of application In battlefield command communication field, including amphibious operations as a important application environment.Combined with today's world has practical demand for amphibious operations,So researching the Ad hoc network and its primary problem routing protocols, and establishing Tactical Ad hoc communication network which is suitable environment characteristics of the amphibious operations, finally providing operational commande with communication security references and opinions, have important practical significance for improving the ability of the army of the amphibious operations.This paper focuses on the Marine Corps which is undertaking crucial task of amphibious operations as the major research object,to preliminaryly explora how to construct the Tactical Internet in amphibious operations.First of all, in the deep analysis of the conventional establishment system and the combat style of the Marine Corps, this paper puts forward a Tactical Internet network model which is based on a layered Ad hoc network structure for simulating the marines tactical communication network.,and focuses on Tactical Ad hoc network of Marine brigade.Second,the paper researchs node mobile model in the battlefield environment,designs move models for Ad hoc network in different combat phase of amphibious operations.It can really reflect node properties and ensure real reliability of simulating the routing protocols.Finally, based on the design of the mobile model, the author use the NS2 simulation platform to simulate and realize Marine brigade's tactical communications environment in different stages of amphibious operations,such as the assault phase of rushing to the beach formation on ths sea,the assault phase of AAAV composite formation, the stage of armor group attack to the the enemy's defensive perimeter deep, the stage of Marine brigade fully spread forces, the phase of marines conduct city war (street fighting),etc. Through simulating the army's common routing protocol,AODV, DSR, DSDV etc, studying its performance in the different combat phase, the author give the communication security scheme of each Tactical Ad hoc network in amphibious operations application environment.
