Seaborne wireless Mesh network credible cooperative service method

Abstract

The invention discloses a seaborne wireless Mesh network credible cooperative service method. The method comprises the following steps: importing a node credit rating mechanism to stimulate node cooperation, constructing a virtual cooperative service system based on a Mesh network and credible evaluation, and accomplishing the credible and reliable transmission of a network task; specifically, taking the credibility, the contribution degree, the available bandwidth, the computation capacity, the link quality and like of the nodes as feature attribute for representing the node, selecting a cooperative service node by a MCR node based on the service capacity evaluation of the node and the cooperative service migration priority in a task driving way, constructing a virtual cooperative servicesystem to realize resource fast fusion and providing reliable service for a user. A simulation experiment shows that the provided virtual cooperative service organization model can effectively solvethe problems of congestion, single point failure and low data distribution efficiency in the wireless cooperative communication system under a marine island environment, and the quality of service ofthe Mesh network is improved.

Description

technical field [0001] The present invention relates to the technical field of maritime wireless cooperative communication, in particular to a method for trusted cooperative communication of a maritime wireless Mesh network. Background technique [0002] In recent years, my country has paid more and more attention to the research on ocean and island communication. At present, my country's established marine satellite communication system includes satellite Emergency Position Indicating Radio Beacon (EPIRB), Maritime Satellite System (INMARSAT) and Beidou satellite navigation system. The satellite emergency radio position indicating beacon can realize the functions of emergency alarm, ship position identification, positioning and position inquiry. The maritime satellite system includes a variety of functional systems to complete communication functions such as voice, fax, maritime broadband data, video, and mobile phone text messages. The Beidou satellite navigation system ...

Problems solved by technology

[0005] The present invention is aimed at the environment of marine wireless Mesh network communication, which is restricted by factors such as complex and changeable environment, heterogeneous communication network, especially the construction of stations on uninhabited islands and reefs, and energy constraints, which lead to uneven distribution of network nodes. When data communication is faced with the problem of non-cooperation due to subjective or objective reasons such as node single-point failure, excessive load or link limitation, congestion, etc., a virtual collaborative service organization model based on node credibility evaluation is proposed. By introducing node reputation The evaluation mechanism encourages node collaboration and builds a virtual collaborative service system to complete trusted and reliable transmission of network tasks
