Research on selective trust-path search and aggregation in distributed environment by Yan-lin QIN, Xiao-ping WU, Jian-xin GAO

“…Current trust models based on reputation had some disadvantages in characterizing recommendation credibility and dealing with Trust-Path Search and aggregation.To solve these problems,an updating algorithm for recommendation credibility was proposed considering factors of time decay,recommendation inosculation and success transaction rate.Furthermore,a selective search-algorithm for trust-path in distributed environment was presented.The algorithm uses recommendation credibility,evaluation similarity and trust-path length as its control parameters and can evade malicious nodes directly in the process of searching.It can also stop the search for unnecessary trust-paths and execute the search for paths containing valuable recommendation.Lastly,trust aggregation method was given by using an advanced combining algorithm in D-S theory of evidence.Simulation results show that compared with existing trust models,the proposed model is more robust on defending attacks of various malicious nodes.…”

RSU-coordinated multichannel MAC protocol in vehicular ad hoc network by Caixia SONG, Guozhen TAN, Nan DING

“…A road side unit (RSU)-coordinated multichannel media access control (MAC) (RMM) protocol was proposed in vehicular ad hoc network,which aimed to improve the transmission efficiency of non-safety messages.Under the coordination of RSU,nodes had more opportunities to make SCH reservations on control channel,and the contention-free message transmissions were thus realized.The proposed RMM protocol could use the service channel during the whole synchronization interval for non-safety message transmissions,and thus the saturated network throughput and channel utilization were improved,and the transmission delay was reduced.Compared with other existing protocols,extensive analysis and simulation results demonstrate the superiority of the RMM protocol.…”

A survey of key issues of URLLC in industrial internet of things by Han WANG, Lei DIAO, Mengling WANG, Xin RONG, Jiamin LI, Xiaohu YOU

“…In the age of 6G internet of things, massive terminal devices are connected intelligently to explore environmental information to improve life quality and create a more intelligent world.With the development of economic society and industry, the number of industrial nodes in the industrial internet of things (IIoT) grows at an significant speed.The real-time transmission and exchange of information between these industrial nodes puts forward higher requirements for communication delay and reliability.Under limited time-frequency resources and strict communication quality requirements, in order to ensure ultra-reliable and low-latency communication (URLLC) of massive terminals in IIoT, it is necessary to analyze the existing key problems from the aspects of low delay, reliability, energy efficiency, spectrum efficiency and scalability.In the scenario of IIoT, combined with the characteristics and requirements of URLLC, the key issues of communication in IIoT were studied, including challenges and opportunities in active user detection, random access, resource allocation and convergence of communication and computation.After summarizing and analyzing the key issues and existing technologies, the future research direction was proposed.…”

High-throughput and low-overhead probabilistic routing based on multi-player bargaining game for opportunistic networks by Zhi REN, Jian-wei SUO, Wen-peng LIU, Hong-jiang LEI, Qian-bin CHEN

“…To address the problems existing in the present probabilistic routing based on bargaining games,including unidirectional transmission of messages degrades the success ratio,depending on the virtual money decreases the purchasing power of nodes,and redundancy exists in the interaction process of messages,an routing algorithm based on multi-player bargaining game for opportunistic networks,HLPR-MG,was proposed.Through extending the two-player game to a multi-player bargaining game,introducing the barter trade to enhance purchasing power of nodes,and improving the existing interaction mechanism to reduce the times of game,proposed algorithm achieves the effect of increasing network throughput and decreasing control overhead.Theoretical analysis verifies the effectiveness of HLPR-MG,and simulation results show that HLPR-MG improves the network throughput and success ratio at least 3.63%,and reduces the control overhead and average end-to-end delay by more than 17.76% and 4.03%,respectively,as compared to the classical GSCP and BG algorithms.…”

Cache replacement strategy based on content value by Dan HUANG, Rongfang SONG

“…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.…”

Transmission characteristics of air-ground channel in aerial communication platform by Xiaobin FU, Baohui ZHENG

“…Satellite communication can solve the problem of global communication,at the same time,it follows the problems of difficult deploy and limited satellite resources.Aerial communication platform is consisted of aircraft with payload communication and not more than 10 km from ground.The platform communicating with ground nodes can solve the weakness of traditional satellite communication.The loss of air-to-ground channel was analyzed to model the air-to-ground wideband channel in Ku and Ka band.The consequence of theory and simulation demonstrates that the fading of the model has serious influence on transmission performance.In low elevation transmission,the value of K-factor is small because of multipath reception.Simulation results show that orthogonal frequency division multiplexing (OFDM) can be a good candidate for wideband communications to transmit payload data from aerial platform to ground station.…”
