Efficient broadcast transmission algorithms based on opportunistic network coding by Ji LU, Cheng-ke WU, Song XIAO, Ran ZHANG

“…Opportunistic network coding (ONC) based broadcast transmission algorithms were proposed to improve the transmission efficiency for wireless single-hop networks.Based on the traditional wireless broadcast transmission model,ONC based solo combination packet broadcast transmission (ONCSB) algorithm and ONC based multiple combination packets broadcast transmission (ONCMB) algorithm were osed respectively.By employing the method of combination different lost packets with different strategies,the ONCSB and ONCMB can improve the throughput with recovering lost packets via a combination packet efficiently.The simulation results show that either ONCSB or ONCMB can lead to better transmission bandwidth performance compared with other algorithms under different wireless channel conditions.…”

Improved DFA algorithm based on multi-dimensional finite automata by ONGYang-yang G, IUQin-rang L, ANGZhen-xi Y, HAOXiang-yu S, INGChi-qiang X, IAOHui-juan J, ENGZhi-bin P

“…Compiling multiple regular expression signatures into a combined DFA can blowup in state and storage space.Explanations from the prospective of information theory and multi-dimensional mathematical model were proposed fo-cusing on the most serious state explosion.Redundancy states were divided into zero-dimensional ones and one-dimensional ones.The former were compressed by dimension,and the later were dynamically built.The space com-plexity of the model came to the theoretical lower bound by the above methods.Then the multi-dimensional finite auto-mata (MFA) was proposed with the model.Experiments show that,the construction time taken by MFA is slightly less than XFA and is 2～3 orders of magnitude lower than DFA,STT redundancy compression algorithms and Hybrid-FA; the memory space of MFA is slightly higher than XFA,but is 1～2 orders of magnitude lower than DFA,STT redundancy compression algorithms,mDFA and Hybrid-FA; in the aspect of matching time,MFA ranks after DFA and Hybrid-FA,but ranks before XFA,and it achieves 1～2 orders of magnitude lower than that of STT redundancy compression algo-rithms and mDFA.…”

Task distribution algorithm based on community in mobile crowd sensing by Hao LONG, Shukui ZHANG, Yang ZHANG, Li ZHANG

“…A community-based task distribution algorithm was proposed to solve the problem of the validity of mobile crowd sensing (MCS) task distribution.By calculating the minimum spanning tree (MST),the connection parameter (CP) and the community convergence degree (CI) between the mobile nodes,the behavior patterns of the users were abstracted and identified to rationally divide the nodes into different communities.Then,the eigenvalue matching degree of the community behavior patterns with the sensing task was calculated.According to the matching degree,the distribution of the corresponding tasks was completed by the central node of the community.The simulation results show that the proposed method can effectively improve the accuracy of the task distribution and the task completion rate,and save the time cost of the task completion.…”

Adaptor signature scheme based on ISRSAC digital signature algorithm by Yanshuo ZHANG, Ning LIU, Yuqi YUAN, Yatao YANG

“…The adapter signature scheme can provide good properties of atomic exchange in the block chain, and has been widely used in practice.A new adapter signature scheme was constructed based on a digital signature algorithm for improved security of RSA cryptosystem (ISRSAC).After proving that the proposed scheme satisfied the correctness of the pre-signature, unforgeability, adaptability of the pre-signature, extractability of the evidence and the security of the signature scheme, it was compared with the adapter signature scheme based on the SM2 digital signature algorithm, the Schnorr-based adapter signature scheme and the ECDSA-based adapter signature scheme.And these schemes were analyzed in terms of time overhead and main calculation amount.The analysis results show that the proposed scheme is similar to other schemes in terms of time overhead, but the proposed scheme expands the application scenarios of ISRSAC algorithm in the current environment, and through the combination of ISRSAC algorithm and adapter signature technology, the selection of adapter signature is more flexible and can have a wider range of applications.…”
