Problems solved by technology

2. Path extension
Although this method combines the two routing strategies of the shortest route and random routing, due to the lack of control over the routing strategy, the data packet may never reach the base station

Embodiment

[0052] A source location privacy protection method based on a fan-shaped area in WSNs, the steps of which include:

[0053] Step 1: If figure 1 Shown, the selection of intermediate nodes. Due to the existence of the visible area, not all areas can be candidates for intermediate nodes. Only the area outside the tangent line of the visible area in the figure can become the candidate area of ​​the intermediate node, that is, the area outside the dotted line in the vertical direction in the figure. When selecting an intermediate node, the source node will first determine the hop number h' of the data packet and the direction α of the data packet transmission, and the hop number must be greater than the scope of the visible area. Since it is impossible for data packets to be transmitted in strict accordance with the specified direction, each node has a transmission range, similar to VBF routing, and the place where the final hop count is 0 becomes an intermediate node.

Abstract

The invention provides a source location privacy protection method based on sector areas in WSNs. The method comprises the following steps: firstly dividing a confusion ring into multiple sector areas; secondly, selecting confusion arcs in the divided sector areas, meanwhile for fairness, selecting the confusion arcs according to the rand function; then, in order to deal with the hop-by-hop backtracking of the attacker, randomly performing +n or -n operation, randomly selecting a confusion arc to serve as an initial location, so that the sum of final weights is 0, a closed loop is formed, andthe relevance among data packets is reduced; and finally, in order to further reduce the relevance and the confidentiality, adding a confusion mechanism. The relevance among data is further reduced byencryption, decryption, out-of-order, abandonment and other series of operations, and the position privacy of a source node is protected at last.

Description

technical field [0001] The invention relates to a source location privacy protection method based on a fan-shaped area in WSNs, and belongs to the technical field of wireless sensor network security support. Background technique [0002] Wireless sensor networks have occupied an important position in various fields, and the research on various directions has become active, especially in the fields of natural environment and military defense, WSNs play an important role that cannot be ignored. Thanks to the development of many auxiliary technologies, such as system-on-chip and embedded technology, WSNs have been widely used in military, intelligent transportation, environmental monitoring, medical and health and other fields. As a distributed sensor network, WSNs is a multi-hop self-organizing network system formed by a large number of sensors that can perceive and inspect the external world through wireless communication. And process the object information that needs to be ...
