A Low Resource Consumption Clone Detection Method for Multi-Base Station Wireless Sensor Networks

To make up the existing deficiencies of clone attack detection methods of wireless sensor networks, a low resource consumption clone detection method (MSCD) for multi-base station wireless sensor networks is proposed. MSCD has the following characteristics: (1) Running in each ring network with base station as the center and using nodes in non-hotspot area to complete clone attack detection, which reduces the effect of clone attack detection on the network lifetime; (2) Combine the head node rotation mechanism and the backup head node mechanism to ensure the energy balance of the network; (3) The ring head node path can find clone nodes that come from different local networks, which makes the MSCD method be suitable for the whole multi-base station network. Meanwhile, in the detection domain of the head node, local broadcast is used to ensure the encounter of legitimacy verification messages and witness nodes; (4) It is proved theoretically that the clone detection probability of MSCD can reach 1 when the witness is credible. The theoretical analysis and the simulation results show that the MSCD clone detection probability is still above 98% when the number of clone nodes accounts for 10% of the total number of nodes, and the network lifetime and storage requirements are significantly better than the existing similar methods.
