Multi-objective optimization placement strategy for SDN security controller considering Byzantine attributes by Tao WANG, Hongchang CHEN

“…By giving the software defined network distributed control plane Byzantine attributes, its security can be effectively improved.In the process of realizing Byzantine attributes, the number and location of controllers, and the connection relationship between switches and controllers can directly affect the key network performance.Therefore, a controller multi-objective optimization placement strategy for SDN security controllers considering Byzantine attributes was proposed.Firstly, a Byzantine controller placement problem (MOSBCPP) model that comprehensively considered interaction delay, synchronization delay, load difference and the number of controllers was constructed.Then, a solution algorithm based on NASG-II was designed for this model, which included the initialization function, the mutation function, the fast non-dominated sorting function and the elite strategy selection function.Simulation results show that this strategy can effectively reduce interaction delay, synchronization delay, load difference and the number of controllers, while improving control plane security.…”

Botnets’ similarity analysis based on communication features and D-S evidence theory by ZANG Tian-ning1, YUN Xiao-chun1, ZHANG Yong-zheng2, MEN Chao-guang1, CUI Xiang2

“…A potential hidden relationship may exist among different zombie groups.A method to analyze the relationship among botnets was proposed based on the communication activities.The method extracted several communication fea-tures of botnet,including the number of flows per hour,the number of packets per flow,the number of flows per IP and the packet payloads.It defined similarity statistical functions of the communication features,and built the analysis model of botnets relationship based on the advanced dempster-shafer（D-S） evidence theory to synthetically evaluate the simi-larities between different zombie groups.The experiments were conducted using several botnet traces.The results show that the method is valid and efficient,even in the case of encrypted botnet communication messages.Moreover,the ideal processing results is achieved by applying our method to analyze the data captured from the security monitoring platform of computer network,as well as compare with similar work.…”

Controlling imported malaria cases in the United States of America by Bassidy Dembele, Abdul-Aziz Yakubu

“…We extend the mathematical malaria epidemic model framework of Dembele et al. and use it to “capture” the 2013 Centers for Disease Control and Prevention (CDC) reported data on the 2011 number of imported malaria cases in the USA. Furthermore, we use our “fitted” malaria models for the top 20 countries of malaria acquisition by USA residents to study the impact of protecting USA residents from malaria infection when they travel to malaria endemic areas, the impact of protecting residents of malaria endemic regions from mosquito bites and the impact of killing mosquitoes in those endemic areas on the CDC number of imported malaria cases in USA. …”

Nettree for maximum disjoint paths with length constraint in DAG by Yan LI, You-xi WU, Chun-ping HUANG, Zhi-ying ZHANG, Zhen-xiang ZENG

“…The problem of the maximum disjoint paths in directed acyclic graphs(DAG)was researched which is to find the maximum disjoint paths with length k between two given vertices.A greedy algorithm named greedy path(GP)was proposed to solve the problem.GP transformed a DAG into a nettree with depth k+1 at first.Then the number of root-leaf paths for each node of the nettree was calculated to achieve the number of total paths for each vertex of the DAG.In order to obtain an optimized disjoint path,GP selected the node in the(k+1)th level of the nettree as the current node,and searched for the optimized parent in the usable parents whose number of total paths was minimal.This process was iterated,until there was no disjoint path.The space and time complexities of GP are O(wkn(p+q))and O(kn(p+q)+n²).To evaluate the performance of GP,an algorithm which can create artificial DAG with known maximum disjoint paths was also proposed.Experimental results show that GP can get better performance than other competitive algorithms.…”

Security versus reliability analysis for multi-eavesdropper cooperation wireless networks with best relay by Mei-ling LI, Zeng-shou DONG, Gang-fei WANG, Zhao-ming LU

“…Physical-layer security could be used to effectively combat eavesdroppers and the transmission reliability of the main link could be improved.A wireless relay network with multiple both decode and forward eavesdroppers and relays were considered,in the presence of the link from source to destination.A best relay selection scheme based on multieavesdropper’s cooperation was proposed,and the outage probability and the intercept probability was deduced under both schemes without relay and with best relay.Then,the security and reliability influenced by different relay selection schemes were analyzed.The simulation results show that the achievable channel capacity at the destination node and the system outage probability are directly affected by different relay selection scheme.Lower system outage probability can be achieved by the proposed scheme,and the system outage probability and intercept probability are both decreased with the increase of the number of relays.The intercept probability increases with the increase of the number of eavesdroppers,which,however,can be reduced by increasing the number of relays to ensure the main link’s reliable transmission.…”

Small cell discovery based on TOA fingerprint database by Yang CHEN, Zhenzhu LEI, Bin SHEN

“…In the scenario that a large number of small cells are deployed in the mobile communication network,the number of carriers to be detected by the user equipment (UE) in inter-frequency scanning is considerably larger than that in the conventional network deployment scenarios.This procedure may consume tremendous amounts of UEs’ energy.In order to solve this problem,a small cell discovery (SCD) scheme based on TOA fingerprint database to alleviate intensive energy consumption was proposed when the UEs try to find their potential serving small cells.The proposed scheme reduces the energy consumption of the UE by decreasing the number of unnecessary inter-frequency detection.The simulation results verifiy that the proposed scheme,compared with the existing SCD strategy using received signal strength (RSSI) based radio maps,has better anti-noise performance and higher accuracy.In addition,it can effectively help the high-speed UE avoid performing inter-frequency detection,and hence increase the rate of the UE being successfully connected to the appropriate small cell.…”
