Problems solved by technology

Among them, the optimal path selection is the core issue of network routing, and the routing methods currently used in mobile communication mainly include flood routing and random routing. The relay node that receives the information transmits the information to its surrounding nodes until the destination node establishes a link after receiving the information. This method has a small delay and a fast connection establishment, but the signaling overhead is relatively large; the random routing method The communication source node randomly selects nodes around to send information until a path that can reach the destination node is selected. This method is more random, the stability of the path is poor, and the delay is relatively large.

example

[0023] Assuming that there are three connectable paths from the source node to the destination node, the multiplicative cost parameters of the relay nodes in the first and second paths are both 0.97 and 0.98, and the multiplicative cost parameters of the relay nodes in the third path The additive cost parameters are 0.82, 0.83, while the additive cost parameters in the first path are 4, 3, 3, and the additive cost parameters in the second path and the third path are 1, 2, 1. Compare the cases of the two paths:

[0024] When the source node communication revenue value is 12, the revenue residual value of the first path is 1.487, the revenue residual value of the second path is 7.427, and the revenue residual value of the third path is 4.337.

[0025] When the source node communication revenue value is 20, the revenue residual value of the first path is 9.092, the revenue residual value of the second path is 15.032, and the revenue residual value of the third path is 9.782.

Abstract

The invention provides a method for analyzing path cost of mobile self-organized network, comprising: step 1: a communication source node gets the multiplicative cost parameter, the additive cost parameter and the income of this time of communication when beginning the communication; step 2: the route which gets the most income surplus in the multi-jump route which can reach the destination node in the route list is calculated out as the data transmission rout in this time of communion; step 3: the multiplicative cost and the additive cost in the real transmission process is calculated, the route cost information is feed back to the communication source node to refresh the cost parameter in the route list. The invention has the advantages that the communication link of the mobile self-organized network has higher stability and the route cost has less consumption. Under different communication income, the invention can provide more appropriate route for data transmission, which simplifies the route choosing of the mobile self-organized network.

Description

technical field [0001] The invention belongs to the technical field of network communication, relates to a self-organized mobile communication routing process in the network, and in particular to a mobile self-organized network path cost analysis method. Background technique [0002] With the development of mobile communication network technology, the center of the network will be gradually marginalized, and a multi-hop self-organizing network will be formed among mobile users. Therefore, the routing problem in the mobile network will become more prominent. Among them, the optimal path selection is the core issue of network routing, and the routing methods currently used in mobile communication mainly include flood routing and random routing. The relay node that receives the information transmits the information to its surrounding nodes until the destination node establishes a link after receiving the information. This method has a small delay and a fast connection establish...
