Problems solved by technology

[0004] Aiming at the deficiencies in the prior art and solving the problem of how to reduce a large amount of routing protocol overhead caused by the flooding problem in the Ad hoc network in the prior art, the present invention proposes an improved Gossip based on the average node degree in the Ad hoc network The routing method and device improve the Gossip routing algorithm used in the mobile self-organizing Ad hoc network. The key of the Gossip routing algorithm is to determine the probability of each node forwarding the message. The present invention combines the introduction of the rumor forwarding probability p with the average node degree The combination of not only solves the problem of excessive routing overhead caused by the flooding algorithm, but also ensures the reliability of network message transmission

Abstract

The invention discloses an improved Gossip routing method and device based on the average node degree in an Ad hoc network. The method includes: receiving a node routing table message to calculate the average node degree, and the average node degree is one hop of all nodes in a certain area The average number of adjacent nodes within the range; determine the false rumor forwarding probability according to the relationship between the node degree of the current node and the average node degree; determine the rumor forwarding probability according to the predefined false rumor forwarding probability and the relationship between the rumor forwarding probability. By combining the introduction of the rumor forwarding probability p and the combination of the average node degree, it not only solves the problem of excessive routing overhead caused by the flooding algorithm, but also ensures the reliability of network message transmission.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to an improved Gossip routing method and device based on an average node degree in an Ad hoc network. Background technique [0002] In recent years, due to the unique characteristics of the mobile ad hoc Ad hoc network, it has been widely used in various scenarios. Among them, many routing protocols are applied on the basis of the flooding algorithm, and the application of the flooding algorithm in the Ad hoc network makes many unnecessary messages forwarded, which brings a lot of routing overhead. Although some researchers have proposed many flooding optimization schemes, the optimization effect is not satisfactory, and there are still many unnecessary message propagation, which increases the overhead and affects the overall performance of the Ad hoc network. [0003] To sum up, in the prior art, there is still no effective solution to the problem of how to reduce a l...
