Embodiment

[0040] like figure 1 , a mobile base station position privacy protection method in a wireless sensor network, the mobile base station moves around the regional center point of the wireless sensor network, and the time for the mobile base station to move around the network for one week is less than the maximum delay between the data required by the application from being generated to being collected by the base station; and The distance between the current position of the mobile base station and the center point of the area varies with time and is random.

[0041] Assuming that the current position of the mobile base station is A(X, Y), the method for the mobile base station to determine the next mobile position A' is as follows: position A' has three possibilities: (1) a node one hop ahead of position A; (2) The position in the left-hand direction of position A; (3) the position in the right-hand direction of position A; the probability that the mobile base station selects the...

Abstract

The invention discloses a privacy protection method for the position of a mobile base station in a wireless sensor network. The mobile base station moves around the central point of the wireless sensor network; the distance between the current position of the mobile base station and the central point changes with time and is random. When the node has data to send, the source node initiates radial routing along the two directions of the network radius. During the routing process, the data packet is stored on each node of the routing path node; when the mobile base station moves, each time it passes through a node stay time t, and broadcast query information to check whether there is any data that needs to be sent to the mobile base station. After the sensor nodes within the communication range receive the broadcast query information, if there is data that needs to be transmitted to the base station, the stored data packet All are sent to the mobile base station. The inventive method can effectively protect the location privacy of the mobile base station, reduce the probability of being attacked, has high security, and has better performance in terms of energy consumption and required storage capacity of nodes.

Description

technical field [0001] The invention belongs to the field of privacy protection of wireless network base stations, in particular to a method with the functions of data collection delay guarantee and base station location privacy protection. Background technique [0002] A wireless sensor network is a wireless network composed of a large number of sensor nodes that communicate with each other through multi-hop wireless links and in a self-organizing and multi-hop manner. It can be widely used in industrial monitoring, agriculture, civil, environmental monitoring, battlefield , ocean, fire and other special environments and applications, it is considered to be one of the key basic technologies of the future important IoT network. A crucial issue in the research of wireless sensor networks is the location privacy protection of the base station. The privacy protection problem of the base station is to prevent the attacker from knowing the location of the base station by adopting...
