Problems solved by technology

Although the strategy of combining marking and logging has a certain degree of compromise in terms of storage capacity and communication cost, it still cannot change the energy consumption and storage capacity in the area near the base station. There is a large residual imbalance that affects the performance of these strategies

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] The source tracking method of the wireless sensor network in the embodiment of the present invention adopts the source tracking strategy of logging combined with migration (logging joint migrating, LM), including the following steps: setting the first one in the direction from the remote base station to the base station to log all the tag information Or the migrating ring is the first mitigation ring (first alleviation crown, FAC). Before the routed data packets reach the first mitigation ring, each node marks the received data packets. When the number of packet markings reaches Log after the preset number of times; if the remaining storage space of the log node is less than a preset value (such as 15%), it will be reversely migrated (migrating) to the node in the remote base station area for storage; when the data packet reache...

Abstract

The invention discloses a wireless sensor network source tracing and tracking method. The method comprises the following steps that (1) the first ring performing logging or migrating on all tabbed information in the direction from a far base station to a base station is set as the first mitigation ring; (2) before routing data packages arrive at the first mitigation ring, all nodes sign the received data packages, logging is performed when the number of the signed data packages reaches a preset number, and the data packages are reversely migrated to the nodes of the area of the far base station to be stored if the residual memory space of the logging nodes is smaller than a preset value; (3) after the data packages arrive at the first mitigation ring, and all nodes perform logging on the received data packages. According to the method, by directly reducing energy consumption and storage requirements of a hot spot region, the service life of a network can be directly prolonged, the storage requirements of the nodes are reduced, and therefore the network performance is improved.

Description

technical field [0001] The invention relates to the field of wireless sensor networks, in particular to a source tracing method for wireless sensor networks. Background technique [0002] At present, there are two main strategies applicable to wireless sensor network traceability, one is the method using data packet marking (marking), and the other is the method based on log (logging). [0003] The method of using data packet marking (marking) is that in the process of data routing, the intermediate node adds the path passed by the route to the end of the data packet, so that if the malicious data packet can be obtained, the path information in the data packet can be extracted. Knowing the routing path of the data packet (partial or all of the routing path information), if the number of malicious data packets reaches a certain level, the information of the malicious source node can be fully known, so that the source of the malicious node can be traced successfully. The adva...
