However, the disadvantage of this method is that the two-layer routing method is used, which splits the close connection of the entire network, so that each node cannot obtain the information of the entire network, resulting in the selected routing path being loca

Abstract

The invention discloses a load balancing routing method suitable for an air-ground integrated network. The method specifically includes the following steps that: a new routing criterion formula is formed, then the formula is used to measure the links of the air-ground integrated network, so that link weights can be obtained and are saved to a link weight list; neighboring nodes exchange respective link weight lists with each other constantly, so that each node in the air-ground integrated network can obtain the weights of the links of the whole network and selects three routes for arriving at any other node from a whole-network link weight list; and a route with highest transition probability is selected as a working route to transmit data packets. The working route selected by the using the method of the invention is close to global optimum; and the working path can be adjusted adaptively according to the variation of the load of the air-ground integrated network, and therefore, the possibility of network congestion can be reduced.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to a load balancing routing method suitable for an air-ground integrated network in the technical field of near-space communication networks. The invention can effectively balance the load of the air-ground integrated network in the case of emergency communication, and reduce the possibility of network congestion. Background technique [0002] The air-ground integrated network can more effectively realize space communication and accelerate the development of the information age, which is an inevitable trend in the development of information science and technology. Air-ground integrated network includes near-space network, terrestrial optical fiber network and air-ground integrated network. Due to geographical differences, air-ground integrated networks may cover sparsely populated areas, such as polar regions and remote areas, or densely populated and data-intensive are...
