Wireless mobile ad hoc network clustering cross-layer communication control method, system and application

Abstract

The invention belongs to the technical field of wireless communication, discloses a wireless mobile self-organizing network clustering cross-layer communication control method, system and application, compares the maximum throughput of nodes using different communication radii, and obtains the optimal density of nodes under this density Communication radius; divide time periodically into time slices, in each time slice, divide into neighbor discovery period and data transmission period; after each node detects the node density around itself, determine the appropriate communication radius, In the data transmission stage, the routing mechanism of the clustering cross-layer protocol HCVCR with variable communication radius is based on the routing discovery and establishment mechanism of passive routing AODV. The present invention improves the space division multiplexing efficiency of the area by using a relatively small communication radius in the area where the nodes are dense, and the nodes can access the channel faster; the area where the nodes are sparse enables a larger communication radius, avoiding The emergence of isolated nodes improves the overall throughput of the network.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a control method, system and application of wireless mobile ad hoc network clustering cross-layer communication. Background technique [0002] In recent years, both the maritime industry and the traditional fishery in my country have been developing rapidly, and the number of ships operating at sea is gradually increasing. Therefore, in order to meet the needs of marine fishing communication, ensure the safe operation of marine vessels, and even meet the entertainment needs of marine operators, it is necessary to vigorously develop marine fishing communication equipment and use communication protocols with more stable performance. Ad hoc network has the characteristics of no control center, self-organization, multi-hop routing and dynamic routing, and is especially suitable for occasions where it is difficult to establish basic communication facilities ...

Problems solved by technology

[0010] (3) In the existing Adhoc network, there are isolated nodes that cannot communicate with any node in the area where the nodes are relatively sparse. In the area where the nodes are dense, because of the existence of carrier sensing, when there are nodes transmitting data, the nodes in this area will be silent on a large scale , leading to a drastic reduction in the capacity of the network

[0012] The acquisition of cross-layer information and the use of cross-layer information to establish routing algorithms are difficult to design, and there are relatively many factors to consider; the neighbor node discovery algorithm requires that the neighbor nodes detect the speed quickly and sufficiently accurately, and the difficulty is relatively large; for node communication in the network In the case of different radii, corresponding algorithms also need to be adopted, and the design is more difficult
