HashTrie:a space-efficient multiple string matching algorithm
Published 2015-10-01“…The famous multiple string matching algorithm AC consumed huge memory when the string signatures were massive,thus unable to process high speed network traffic efficiently.To solve this problem,a space-efficient multiple string matching algorithm-HashTrie was proposed.This algorithm adopted recursive hash function to store the patterns in bit-vectors in place of the state transition table in order to reduce space consumption.Further more it made use of the rank operation for fast verification.Theoretic analysis shows that the space complexity of HashTrie is O(|P|),which is linear with the size of pattern set |P|and is independent of the alphabetsize σ.The space complexity is superior to the complexity O(|P|σlog|P|)of AC.Experiments on synthetic datasets and real-world datasets(such as Snort,ClamAV and URL)show that HashTrie saves up to 99.6% storage cost compared with AC,and in the meanwhile it runs at a matching speed that is about half of AC.HashTrie is a space-efficient multiple string matching algorithm that is appropriate to search large scale pattern strings with short lengths.…”

Online placement algorithm of service function chain based on knowledge graph
Published 2022-08-01“…The emergence of new network services such as immersive cloud XR and holographic communication puts forward higher requirements for network service quality.To ensure the availability of network services, the network service delay and reliability must be controlled within a certain quality of service according to the attributes and dependencies of network functions.However, the traditional network representation forms, such as bitmap and matrix, cannot cover these key network information, resulting in the information loss in the input stage of the algorithm, which leads to the deviation of the calculation results.Therefore, in order to accurately extract user needs and reflect the dynamic changes of network resources, knowledge graph was adopted to represent the network and its services, an online placement algorithm of service function chain based on knowledge graph was proposed.Based on this, a relationship alignment method based on editing distance was designed to guide the online placement of service function chains under complex dependency relationships.Experimental results show that the proposed algorithm can improve the placement accuracy of service function chain by 10%~15% and reduce the average network energy consumption by about 13%.The proposed algorithm has low complexity and high timeliness.…”

A Novel Resource Allocation Algorithm for OFDMA System with Proportional Fairness
Published 2014-06-01“…Existing algorithms couldn't balance system capacity and high fairness well,so a multi-user rate adaptive allocation algorithm was proposed to maximize the capacity of OFDMA system under proportional fairness.Improved maximize the minimum(max-min)user rate model was proposed,the current user was allocated the highest efficiency subcarrier according to the channel efficiency control parameter.If some allocated subcarrier's channel gain was lower than the threshold value,which would be reallocated to another user whose channel gain was highest.Power allocation model was converted into expression of water-filling line; every user's power allocation was resolved according to the resolved water-filling line.Simulation results and analysis show that the proposed scheme can achieve higher capacity and perfect fairness in a variety of SNR cases,while requiring slightly less computation.…”

Published 2021-08-01“…To solve the problems of the low acquisition probability and high computational complexity in satellite high-mobility communications, a new factor graph was designed for acquisition of the high-mobility direct sequence spread spectrum (DSSS) signal, where time-varying Doppler rates were modeled by the random walk model.Based on the proposed factor graph, the turbo iterative DSSS signal acquisition algorithm was proposed.In the Doppler-estimation loop, the negative influence of Doppler frequency offsets and Doppler rates could be eliminated effectively.Then in the code-detection loop, constraints of each chip was used to recover the received signal, to achieve DSSS signal acquisition.Simulation results show that the proposed algorithm is capable of improving the acquisition performance at less 1.3 dB with low computational complexity.…”

Trustworthy service discovery based on a modified ant colony algorithm
