Bottom Line: Due to the limited resources of wireless sensor network, low efficiency of real-time communication scheduling, poor safety defects, and so forth, a queuing performance evaluation approach based on regular expression match is proposed, which is a method that consists of matching preprocessing phase, validation phase, and queuing model of performance evaluation phase.Experiments show that our approach ensures accurate matching and computational efficiency of more than 70%; it not only effectively detects data packets and access control, but also uses queuing method to determine the parameters of task scheduling in wireless sensor networks.The method for medium scale or large scale distributed wireless node has a good applicability.

ABSTRACT
Due to the limited resources of wireless sensor network, low efficiency of real-time communication scheduling, poor safety defects, and so forth, a queuing performance evaluation approach based on regular expression match is proposed, which is a method that consists of matching preprocessing phase, validation phase, and queuing model of performance evaluation phase. Firstly, the subset of related sequence is generated in preprocessing phase, guiding the validation phase distributed matching. Secondly, in the validation phase, the subset of features clustering, the compressed matching table is more convenient for distributed parallel matching. Finally, based on the queuing model, the sensor networks of task scheduling dynamic performance are evaluated. Experiments show that our approach ensures accurate matching and computational efficiency of more than 70%; it not only effectively detects data packets and access control, but also uses queuing method to determine the parameters of task scheduling in wireless sensor networks. The method for medium scale or large scale distributed wireless node has a good applicability.

fig7: Results of node average hops in NS-2.

Mentions: Table 2 demonstrates that we can get a good efficiency promotion from 73.17% to 89.73%. A regular matching comparison was performed with our strategy and normal approach. The average hop and average F(Gi) variation tendency and the number of nodes are shown in Figure 7. L7-Filter and Snort were tested separately. y-axis is hops and x-axis indicates the nodes number. From the results figure, a significant difference can be observed: when nodes are more than 30, the hops number of using Gi decreases sharply.
