“…The red nodes indicate malicious node in Figure 3 . The evaluation will compare three schemes: CEACM-TS, APAC [ 9 ] and GTMS (Group based trust management scheme) [ 8 ], to show that CEACM-TS is a practical design for the tradeoff between keeping out of the interference and transmitting concurrently, comparing their advantages and disadvantages in terms of random packet losses, error packets, data tampering and retransmission, falsification of identity, denial of service, node capture resetting as well as system cost, energy consumption evaluation and error rate of access control test under the condition of simulative human disturbances and attacks. This topology structure is composed of two backbone networks which contains the cluster head node and sensor nodes.…”

“…Following that, the base station periodically multicasts the current state of each group to all group heads. The information encryption access technology can guarantee the integrity and confidentiality of the information packet and can effectively resist external attacks but it cannot guarantee time accuracy [ 9 ]. The Fault Tolerant Time Synchronization Protocol (FTTSP) judges and detects the internal noise of the node based on the difference between the estimated value of the transmission time and the actual value by with fault-tolerance mechanism [ 10 ].…”

Internal reliability and external safety of Wireless Sensor Networks (WSN) data transmission have become increasingly outstanding issues with the wide applications of WSN. This paper proposes a new method for access control and mitigation of interfering noise in time synchronization environments. First, a formal definition is given regarding the impact interference noise has on the clock skew and clock offset of each node. The degree of node interference behavior is estimated dynamically from the perspective of time-stamp changes caused by the interference noise. Secondly, a general access control model is proposed to resist invasion of noise interference. A prediction model is constructed using the Bayesian method for calculating the reliability of neighbor node behavior in the proposed model. Interference noise, which attacks the time synchronization, is regarded as the key factor for probability estimation of the reliability. The result of the calculations determines whether it is necessary to initiate synchronization filtering. Finally, a division of trust levels with bilinear definition is employed to lower interference noise and improve the quality of interference detection. Experimental results show that this model has advantages in system overhead, energy consumption and testing errors, compared to its counterparts. When the disturbance intensity of a WSN increases, the proposed optimized algorithm converges faster with a lower network communication load.
