A recovery method for interrupted data in mobile ad hoc network based on area awareness

Abstract

The invention belongs to a network communication data processing method, and particularly relates to a mobile self-organizing network interrupt data recovery method based on area perception. The mobile self-organizing network interrupt data recovery method based on the area perception includes following steps: step 1) initializing a network and performing dynamical initial allocation on area service providing nodes; step 2) dynamically maintaining and routing the area service providing nodes; step 3) performing routing among normal nodes and between each normal node and each area service providing node; step 4) storing and recovering interrupt information of network nodes. The mobile self-organizing network interrupt data recovery method based on the area perception uses global position system (GPS) positioning technology to obtain area distribution of the network nodes and accordingly achieves division of network areas, sets up the area service providing node for each network subsidiary area, and simultaneously uses the area service providing nodes to complete collection, storage and retransmission of transmission interruption data packets in the areas which are respectively corresponding to the area service providing nodes, and accordingly achieves information recovery of the interruption data packets, and furthermore solves the problem that business data among the nodes is lost under a large scale complex mobile wireless self-organizing network environment.

Description

technical field [0001] The invention belongs to a network communication data processing method, in particular to a method for recovering interrupted data of a mobile ad hoc network based on area perception. Background technique [0002] CN101094119 discloses the "Overlay Network Fault Detection and Recovery Method Based on Fast Switching", which establishes a fault judgment number for indicating how many detection messages are lost in succession to determine the failure of the cover node at the user node, and indicates the agent identity of the node The neighbor state table including the flag bit is used to calculate the sending frequency of detection packets for all neighbors, and establish a neighbor maintenance table including the number of keep-alive packets sent by the neighbor and the sending frequency. If there is no response to the detection message within the number of determinations, the neighbor will be deleted. If the deleted neighbor is an agent node in the area...
