Embodiment

[0040] Such as 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 distance between the current position of the mobile base station and the regional center point changes 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 front position as the next position A' is ε

[0042] The numerator is the number of hops that the mobile base station needs to move for one week, and the denominator is the number of hops that the mobile base stati...

Abstract

The invention discloses a location privacy protection method of a mobile base station in a wireless sensor network. According to the method, the mobile base station moves around the center point of the wireless sensor network; the distance between the current location of the mobile base station and the center point changes with time and is stochastic; when a node has data required to be transmitted, a source node initiates radial routing along the second direction of the radius of the network; in a routing process, data packets are stored in each node of routing route nodes; when moving, the mobile base station stays for t when passing through each node and broadcasts query information so as to query whether data required to be transmitted to the base station exist; and after receiving the broadcasted query information, sensor nodes in a communication range transmit all stored data packets to the mobile base station if data required to be transmitted to the base station exist. With the method of the invention adopted, the location privacy of the mobile base station can be effectively protected, and the probability of being attacked can be decreased, security is high. The method is advantageous in low energy consumption and storage capacity required by the 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...
