Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] Since the shipborne AIS carries geolocation information, the routing protocol based on geolocation information has the advantages of strong scalability, local topology, and greedy forwarding, but the problem of topological holes will be encountered in the greedy forwarding process. In order to solve this problem, the research content is carried out in the following three directions: (1) Research on the use of geographic positioning information such as GPS of neighboring ships to design efficient heuristic functions and heuristic algorithms that bypass topological holes; (2) Establish location service (LocationService) distribution model. Preliminary consideration of the spiral quadrilateral grid model, that is, the closer the service node is, the denser the location server is. (3) Using the release model of location services and the kn...

Abstract

The invention relates to a heuristic routing method utilizing position information in a shipborne adhoc network. The heuristic routing method is characterized by comprising three main modules, namely a geographical position based routing strategy, a topologic void crossing method and a topologic void prediction model, and two auxiliary modules, namely a geographical position service model and a wireless network constraint strategy. According to the heuristic routing method, the existence of the topologic void can be predicted in advance, and the topologic void can be crossed by a geographical information based heuristic algorithm, so that the core technical problem of high-efficiency data forwarding in the shipborne adhoc network is solved.

Description

technical field [0001] The invention relates to the technical field of wireless ad hoc networks, in particular to a heuristic routing method using location information in a ship-borne ad hoc network, which is applied to ship networking communications. Background technique [0002] Current maritime communications such as digital selective calling, single sideband wireless telephones, satellite search and rescue systems, etc., have narrow bandwidth, poor signal stability, and are expensive. The on-board identification system (AIS) stays at the transmission level of one-way 9.6kbps low data rate, and two-way communication still needs to rely on other technical means. In the field of broadband communication, such as 3G network, although its mobile communication network covers a wide range, short-distance ships such as fleet sailing, ships near the port, etc., short-distance ad hoc networking, with a bandwidth of more than several megabytes, is more convenient and cheap than 3G ...
