Embodiment Construction

[0050] In order to facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below in conjunction with the accompanying drawings.

[0051] Such as figure 1 As shown, the present invention provides a mobile sensor network connectivity repair method for cut point faults, and the implementation steps of the present invention will be specifically introduced below in conjunction with the accompanying drawings.

[0052] The cut point node calculates the selection set of each one-hop neighbor node according to the two-hop neighbor table, and then selects an execution node that performs the mobile repair task when a fault occurs from each selection set, and then the execution node will periodically detect the cut point Whether there is a failure, when the cut point fails, it will automatically initiate mobile repair, so that the network can be connected again.

Abstract

The invention discloses a mobile sensor network connection repairing method aiming at a cutting point fault, which is applied to the technical field of wireless sensor networks and aims at solving the problem of network splitting caused by the network cutting point fault in a mobile sensor network. According to the method, the mobile node combination for executing the repair task is selected for the network splitting caused by the potential network cut point fault by executing the node selection algorithm, and unnecessary movement is reduced through the mobile node elimination algorithm in the movement process; and under special circumstances, a speed reduction cascade movement algorithm is adopted to enable the repair time and the total movement distance to achieve an effect of balancing, and whether all partitions are communicated or not is judged according to a communication progress interaction process, so that the purpose of repairing network splitting is finally achieved.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and in particular relates to a repairing technology for network splitting caused by cut point faults. Background technique [0002] With its characteristics of no center, self-organization, multi-hop routing, and dynamic topology, wireless sensor networks are suitable for scenarios where it is impossible or inconvenient to lay network facilities in advance, but fast and automatic networking is required. In personal communications, sensor networks, emergency relief communications, It has been widely used in battlefield environment monitoring and other fields. Although Ad-hoc wireless self-organizing network technology has greatly accelerated the speed of temporary networking communication in these fields, due to its network characteristics, limited power supply and harsh networking environment and other factors, it is very easy to cause failure of individual network nodes.
