Collusion node detection method based on fuzzy evaluation density clustering in Internet of vehicles
Published 2023-07-01“…In order to solve the security problems caused by collusion of malicious vehicles in the open Internet of vehicles environment, a collusion node detection method based on fuzzy evaluation density clustering was designed.The method realized vehicle reputation update through subjective recommendation trust, objective data trust and historical reputation.Two rounds malicious node detection method was designed to detect malicious vehicles, in the first round, fuzzy comprehensive evaluation was used to screen out a single malicious vehicle node, and in the second round, the conspiracy malicious vehicle nodes were searched by the improved density clustering method according to a single malicious vehicle node to ensure the sustainable development of network environment security.Experimental results show that the proposed method has a high recognition rate for malicious vehicles, and when the proportion of malicious vehicles reaches 30%, the detection accuracy can still remain above 90%.At the same time, under the proportion of different malicious vehicles, the detection recall rate and detection F value still remain higher value, indicating that the proposed method has a high stability.For the change of total vehicle nodes, the performance evaluation index shows a small fluctuation and remain within the range from 80% to 100%.…”

Experimental Analysis on Compression Characteristics of Improved Phyllite Filler
Published 2021-01-01“…Soil compression is an important characteristic that affect the construction and operation of improved soft rock filling in mountainous ports.Through adding 5% cement to improve the weakly weathered phyllite filler,setting 4 kinds of rolling loads and 5 cycles of loading and unloading,and using an improved high-pressure lever consolidation instrument,this paper measures the soil strain,compaction and porosity ratio under different stress states,and specifies the change law of compression modulus and resilience modulus during loading and unloading process.The test results shows that:The deformation of the modified phyllite filler mainly occurs in the first loading process,and it increases significantly with the increase of the rolling load.The porosity ratio curve shows a concave shape with the increased cycles of loading and unloading.When the rolling load is 100 kPa,the curve of porosity ratio is nonlinear with the increased cycles of loading and unloading;when the rolling load is 200 kPa,the compression of the soil changes from medium to low with the increase of compaction cycles.At this time,the modulus of resilience takes a minimum value.It is suggested that the 200 kPa roller compaction stress should be used as the first static compaction during the construction of improved soft rock filling in mountainous ports,which should be increased appropriately in the subsequent construction.…”
