specific Embodiment approach

[0035] Step 1: The CC2431 positioning engine is implemented with a function with a simple interface: write the required parameters, wait for the calculation to complete, and then read the calculation result, which is the coordinate of the blind node. The positioning principle is as follows figure 1 .

[0036] Step 2: Aiming at the hidden danger of "multiple identity false information" in the wireless sensor network positioning algorithm, establish a sensor network positioning attack technology based on multiple identity false information. The attack model is as follows: figure 2 shown. When the attack node is not added, the positioning coordinates and RSSI value of the reference node are recorded.

[0037] Step 3: Join the attack node, use the attack node to send different position parameters to the blind node at different times, and the XY_RSSI corresponding function in the attack node:

Abstract

The invention discloses a wireless sensor network security positioning tracking and quantitative evaluation method, and key technologies such as security optimization and performance evaluation of positioning algorithms, and proposes a design scheme for building a wireless sensor network security positioning algorithm and an algorithm security evaluation design scheme. Using the ZigBee wireless positioning system, the principle of the CC2431 positioning engine is a distance positioning method based on the received signal strength indication, that is, using the attenuation of the signal in the propagation process to estimate the distance between nodes, and establishing a wireless sensor network multi-target recognition and positioning algorithm scheme. Firstly, design and realize the multi-target recognition and localization algorithm of wireless sensor network based on RSSI. Secondly, design and implement the sensor network positioning attack technology based on multiple identity false information. Finally, the design and implementation of wireless sensor network security positioning algorithm. Based on the coefficient of variation method, the evaluation of the sensor network positioning algorithm is realized, thereby verifying the effectiveness of the security positioning algorithm.
