Embodiment Construction

[0024] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] figure 1 It schematically shows the address allocation method in the maritime ship ad hoc network. Among them, 101-103 and 105 and 106 respectively denote warships at sea, among which 101-103 are networked group armies that have been assigned fixed IP addresses and constitute the network 104 . Ships 105 and 106 are newly joined nodes in the network, and have not yet been able to establish a stable communication channel with the ship group. Each of these ships is equipped with GPS receivers and can successfully receive GPS signals. And it has an electronic map of the entire network coverage area or can obtain an electronic map of the relevant area through the GPS device, so that it can accurately know its position (coordinates) by receiving the GPS signal. Since each ship is at the same sea level, two-dimensional coordinates can accurately descr...

Abstract

The invention relates to the field of communication, wherein the embodiment of the invention discloses a ships fast self-networking method based on GPS information. The method comprises the followingsteps: an address distributing mode in the self-networking of the sea ships; the division of geographic regions of IP communication according to GPS address information; the selection of address agentships; a ships handover switching work flow based on the GPS information; the packet combining and the cracking process of the ships regions based on the GPS information; and the self-networking optimization of sea / air uniform. The method manages the ships address with different layers and simplifies operation by using GPS address location information and allocating address management subdistricts. Simultaneously, the method can support the dynamic regulation of topology such as the combining and the cracking of the network, etc. By using different address segments of each subdistrict and executing the unified management by the address agent in the subdistricts, the method guarantees the uniqueness of address allocation. When nodes handover switch after cracking and combining the network,each subdistrict uses different address segment, therefore, a handover switching mechanism automatically solves the problems that the address is possibly leaked and repeated in the process of cracking and combining the network.

Description

technical field [0001] The invention relates to the field of communication, in particular to a fast self-organizing network method for ships based on GPS information. Background technique [0002] Each node in the Ad hoc network starts independently, using a set of wireless transceiver devices, which have the functions of host and router at the same time, and have the characteristics of fast networking and rapid response. It is widely used in disaster relief, field construction, military battlefield and other occasions, and belongs to a peer-to-peer network. Since there is no central node, when a disaster occurs, there is no dependence on an important node, and it has high disaster resistance characteristics. The current accuracy of GPS (Global Position System, referred to as Global Satellite Positioning System) has reached 20ns, and it can provide accurate synchronization for each terminal node in the Ad hoc network. The currently applied GPS technology can realize resourc...
