The Application Of Digital-man Tactical Network Radio Routing Protocols

In recent years, Mobile Packet Radio Network Technologies has been widely used in many fields. Mobile ad hoc network ( MANET )is a collection of wireless mobile hosts forming a multi-hop temporary wireless network without the aid of any centralized administration or wired infrastructure. In such a network, each mobile node operates not only as a host but also as a router. This network has a series of the strengths, for example: MANET can be built rapidly and easy, and it is not set measures to by wired network, and so on. MANET can also be used for emergency search, disaster rescue, law enforcement, as a result have the extensively applied foreground.Because moving to rush toward the dynamic state from the topology of a net, making normal regulations road under that environment can't circulate normally from the agreement. Therefore, to under that environment the road became the ambulation from the research of agreement from main topic studied in a net.Firstly, the paper introduced development general situation and its network structural and specials of the ambulation a lead-in net of cent first, moved the safe problem of Mobile ad hoc network to do some discussions immediately after, then analyzed to move to divide several kind roads that a lead-in net adopts at present from the agreement( purpose sequence distance vector road from agreement ( DSDV), dynamic state source road from the agreement ( DSR) and at the time in sequence the road is from the calculate way( TORA), press to need the distance vector road from the agreement. ( AODV) ).Finally gets the conclusion of is: the different road all has from the agreement each from of applied situation and merit and shortcoming, design a kind of all-powerful road to is not realistic from the agreement. A kind of compare solve the way of thinking goodly is an adoption to combine first check type and reaction type road from negotiate of hybrid type road from, its ability at reduce to divide the set as far as possible the premise that postpone descends the low road from the expense of the agreement.
