Abstract
The invention discloses a routing protocol for an offshore centerless ad hoc network. Under the condition that normal transmission of data are not influenced, the finish of command scheduling, data transmission and image information transmission can be ensured quickly, accurately and confidentially. The whole network consists of offshore mobile nodes, wherein any two nodes directly communicate or are relayed by other nodes; each node respectively consists of an antenna, an antenna control unit, wireless transceiver equipment, a wireless network controller, a router, IP (Internet Protocol) security equipment, a switchboard and a plurality of computer terminals; in the centerless ad hoc network, the nodes transmit a route request for broadcasting; request information is broadcasted by adopting a certain communication strategy and is required to be transmitted beyond the transmission range of source nodes; after the nodes receive the request information, addresses of the nodes are filled into a route of a request information data packet before the request information is transmitted; and the route maintenance means that a feedback mechanism is provided and is used for timely modifying the route when the nodes move so as to ensure the consistency of a route table.
Description
Technical field:
A kind of Routing Protocol based on phased array antenna.
Background technology:
Marine work compound at first need be set up information platform, i.e. wireless mobile communication network, and the survivability of network and mobility are vital to forming powerful fighting capacity.The mobile communications network that we often mention all has the center, promptly relies on preset infrastructure to move.Like cell mobile communication systems the support of base station will be arranged, WLAN generally also needs the support of wired backbone.And thisly have the central. set net mode utmost point to be not suitable for work compound, in case the most fatal weakness be control centre and damage the paralysis that will cause whole network, cause the heavy damage of work capacity.
Content of the present invention:
The present invention is exactly to the problems referred to above, and a kind of have powerful survivability and robustness are provided, and is fit to very much the MANET Routing Protocol of marine work compound mode.
For realizing above purpose; This present invention adopts following technical scheme; Whole network is made up of marine mobile node; Direct communication or through other node relaying, each node is formed by antenna, antenna control unit (ACU), wireless transmitting-receiving equipments, radio network controller (WNC), router, IP crypto, switch and many terminals between wherein any two nodes; In the MANET of no center; Node sends route requests broadcasting; Adopt certain communication strategy to broadcast away solicited message; Purpose is to pass to solicited message outside the transmission range of source node (requesting node), and after node was received solicited message, the address with oneself before transmitting it was filled up in the route of solicited message packet; Route maintenance just provides a feedback mechanism, and time update route when node motion is to guarantee the consistency of routing table.
Beneficial effect of the present invention:
Can not influence under the normal transmission situation of data, can be rapidly, accurately, maintain secrecy, guarantee the completion of command scheduling, transfer of data and image information transformation task.
Description of drawings
According to accompanying drawing this present invention is further specified below.
Fig. 1 does not have the center MANET and forms structural representation.
Fig. 2 road table is by the list structure sketch map.
Embodiment
Whole network is made up of marine mobile node; Direct communication or through other node relaying, each node is formed by antenna, antenna control unit (ACU), wireless transmitting-receiving equipments, radio network controller (WNC), router, IP crypto, switch and many terminals between wherein any two nodes; In the MANET of no center; Node sends route requests broadcasting; Adopt certain communication strategy to broadcast away solicited message; Purpose is to pass to solicited message outside the transmission range of source node (requesting node), and after node was received solicited message, the address with oneself before transmitting it was filled up in the route of solicited message packet; Route maintenance just provides a feedback mechanism, and time update route when node motion is to guarantee the consistency of routing table.
After mobile node sets out; Also there is not data message to send out; Then each node is according to the common scanning timetable, in it obtains the time of transmission route, to the positional information of other own and known nodes of its adjacent node transmission; Each node (removing certain node does not remain in the horizon range with interior any other node of net) has basically been recognized the positional information of interior other nodes of net and the topological state of network, and sets up initial routing table thus.
After initial routing table is set up; Each node is except sending packet; Also to periodically send positional information or routing tables own and other nodes; Each node is all preserved a up-to-date routing table to other nodes, and the content of routing table comprises destination node ID, preceding node ID, descendant node ID, hop count, route life cycle and the timestamp of connecing; Each node is every to send once new routing iinformations to adjacent node at a distance from 6 scan periods, and each node may receive the routing iinformation of repetition in a frame like this, and each node will be handled route information so, forms new routing table; When some source nodes have data to send; It copies to the routing iinformation of destination node in the packet of desire transmission from own current up-to-date routing table; When a certain node when its neighbor node is received a packet; To handle as follows:, then store this packet line data of going forward side by side and handle 1. if oneself be destination node.2. if oneself be not destination node, routing iinformation of then indicating in the comparing data bag and the routing table of oneself are chosen the route that the destination node jumping figure is minimum and life cycle is maximum according to timestamp, and are transmitted this data message; A node does not receive any information of a certain adjacent node within a certain period of time; Link down then is described; This moment, this node should be according to the routing table of the updating location information oneself of other nodes of preserving; And in following one-period, the routing table of this bad news and renewal is sent, through behind the certain hour, the routing table that other nodes also can corresponding renewal oneself.
