Efficient communication protocol of group negotiation in VANET
Published 2018-01-01“…An efficient communication protocol of group negotiation was proposed.The protocol adopted self-checking authentication in group to avoid the nodes sending certificates to the authentication center which improved the efficiency of identification.At the same time,the group establishment among nodes which through negotiation ensured the communication confidentiality and prevented the phenomenon of single-point failure.Besides,a group key transmission scheme was proposed to reduce the frequency of authentication for legal vehicles and improve the speed of joining in the group.At the end,theoretical analysis and simulation results demonstrate that the proposed protocol not only meets the security requirements of communication in VANET,but also shows much better performance than previous reported schemes on verification delay,transmission overhead and average delay.…”

Data transmission algorithm of vehicle Ad Hoc network based on channel switching
Published 2018-10-01“…A data transmission algorithm of vehicle Ad Hoc network based on channel switching (DTA) was proposed.In the DTA,three network layers were considered,such as vehicle nodes,relay nodes and sink nodes.The vehicle nodes were classified by the information of vehicle’s driving direction.The vehicle nodes channel distribution and switching mechanism was proposed to reduce the interference of communication.Then a rapid transmission of relay nodes was proposed.A priority transmission method for emergency information was proposed to classify data with different queues and send data as their queues’ priority.Simulation results show that DTA can effectively achieve the rapid transmission of useful information,reduce unnecessary losses of energy,improve the data received rate of sink nodes,reduce the average hop number of data packets and improve coverage rate of data transmission.Under certain conditions,DTA is better than AODV and AODV-L algorithm,and is more suitable for vehicle driving environment of rapid change.…”

Influence diffusion model based on affinity of dynamic social network
Published 2016-10-01“…Recently,influence maximization model is a hot issue in the field of social network influence,while the traditional independent cascade model is generally based on static network with a fixed value of activation probability.DDIC model,which was a dynamic network influence diffusion model with attenuation factor was proposed.It calculated the activation probability between nodes via affinity propagation,and according with dynamic segmentation of social network time slice,calculation of influence on proliferation of next time slice with the current time slice of activation probability performance decay.The experimental results show that the nodes in the DDIC model have more chances to active the neighbor and the average probability of activing of the DDIC model is higher.Further experiments show that influence value via computing with affinity propagation can reflect the process of the spread model more accurately.…”

Published 2018-11-01“…The cache replacement mechanism is one of the important research issues of the content center network.Considering the limited cache space,the reasonable replacement of the cache content becomes a key factor affecting the overall performance of the network.Therefore,a cache replacement scheme based on content value was designed.Considering the dynamic popularity of content,the cost of caching,and the time of the most recently requested,a more realistic content value function was built,and an effective content storage and replacement scheme was designed based on the content value function.Specifically,when the cache space was insufficient,the existing cache contents were replaced according to the value from small to large.Simulation results show that compared with the traditional replacement algorithms LRU,LFU and FIFO,the proposed scheme effectively improves the content cache hit rate of network nodes and reduces the average hops of users’ content acquisition.…”
