However, the design of computation task scheduling policies for MEC systems inevitably encounters a challenging latency optimization problem. Due to the limited radio and computational resources in communication system, a more efficient latency-optimal scheduling policy is urgently needed to meet the ever-increasing computation demands of many new mobile applications. In this paper, we formulate an optimization problem based on partial offloading strategy and transform it into a piecewise convex problem, getting the latency-optimal point by means of sub-gradient method. A simplified algorithm is further put forward to achieve close-to-optimal performance in polynomial time. Therefore, we conclude a simultaneous computing and distribution strategy called SCADS. Simulation results are provided to demonstrate the advantages of our proposed algorithms compared with other baseline strategies.","PeriodicalId":244952,"journal":{"name":"2018 IEEE 18th International Conference on Communication Technology (ICCT)","volume":"240 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124635365","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the dissimilar characteristics among different paths may cause the out-of-order problem at the receiver with limited receiving buffer, which will significantly degrade the overall throughput. Many packet scheduling schemes for MPTCP have been proposed to keep data in-order delivery, but most of them only consider the path latency, ignoring the bandwidth and packet loss rate. In this paper, we propose a new dynamic packet scheduling method for MPTCP. We first use a low-complexity way to estimate the packets sent on other paths concurrently, taking both the bandwidth and packet loss rate into consideration, then modify the scheduling value with the feedback information. Simulation results show that our method can enhance the overall throughput and reduce the unordered packets at the receiver.","PeriodicalId":244952,"journal":{"name":"2018 IEEE 18th International Conference on Communication Technology (ICCT)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124101433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous work on error-correcting codes and physical layer security has assumed a wiretap channel where each user experiences Gaussian noise, but this paper presents the first results evaluating the performance of polar codes on wiretap channels where both the intended recipient and eavesdropper experience varying levels of impulsive noise. The impulsive noise has a symmetric alpha-stable probability density function (pdf) and density evolution is employed with knowledge of this pdf to construct optimal polar codes for an impulsive environment. Simulation results confirm that the bit error rate (BER) at the eavesdropper is always 0.5 for all signal-to-noise ratios, thus always ensuring secure communication, and we present the very interesting result where this is still achieved when the main channel is more impulsive than the eavesdropper's channel.","PeriodicalId":244952,"journal":{"name":"2018 IEEE 18th International Conference on Communication Technology (ICCT)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121726413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The two-layer collection network on the marine surface is firstly constructed, in which sensor nodes send small-scale data to the collection head (CH) node for storage by multi-hop route. The CHs upload data to nearby UAV, which help to save network energy while expanding network coverage. Secondly, the broadcast mode of the Ring Broadcast message can effectively guide search direction of the sensor node routing. Meanwhile the inner-collection nodes select the optimal next-hop node by the fitness function, which helps to balance the energy consumption of each node and search optimal path. Lastly, dynamic routing mechanism in complex environment can quickly search the alternative path to repair route, and thus adapt to the frequent change of MMSN topology. In this paper, the dynamic transmission of UAV mobility and collection network structure are used to realize the high-efficiency transmission of maritime monitoring data, which can effectively improve the network hole problem in harsh maritime environment.","PeriodicalId":244952,"journal":{"name":"2018 IEEE 18th International Conference on Communication Technology (ICCT)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115873233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The decoding process of LT codes is analyzed, which shows that the low decoding success probability of short length LT codes is predominantly caused by lack of degree 1 check nodes (CNs). Based on this observation, a novel improved encoding scheme for short length LT codes over binary additive white gaussian noise (BIA WGN) channels is proposed. A new degree distribution and two weighting factors are presented, which are used to improve the proportion of degree 1 CNs. In addition, by setting a threshold, information nodes (INs) whose degrees are less than the threshold are screened continuously, and then extra degrees were added to these INs to improve the error floor performance of short length LT codes. Furthermore, the design principles of above parameters are presented, enabling the validity and universality of the improved scheme. Simulation results show that the improved short length LT code ($pmb{k=50}$ and 200) can decrease the bit error rate (BER) by up to five orders of magnitude over BIAWGN channels.","PeriodicalId":244952,"journal":{"name":"2018 IEEE 18th International Conference on Communication Technology (ICCT)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133865579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The transmitter light source uses a commercial vehicle lamp to transmit a signal modulated by 64QAM-DMT. The weighted pre-distortion is used to reduce the nonlinear damage caused by amplifiers and photoelectric elements. The optimal performance of the system is achieved by modifying the weight coefficient. The zero-padding is used to improve the performance of the system. A PIN (S6968) is used on the receiver to receive data. By combining these technologies, an aggregate data rate of 315Mbps is successfully achieved in 3-m indoor free space transmission with the BER rate of 10−4 below the FEC limit of 3.8 × 10–3 by using a car headlamp.
