Most of the existing works in WBAN focus on theoretical performance enhancement, whereas works in implementation which is of significance in validation and further research are pretty rare. Therefore, a reliable and efficient system designed both in hardware and software based on the IEEE 802.15.6, named WBAN prototype system, is proposed and implemented in this paper. We constructed the prototype system from modules to system architecture, and conducted a set of experiments to verify the prototype system as well as optimize parameters in IEEE 802.15.6. The prototype system is ascertained to meet basic requirements in terms of quality of service indexes by extensive experiments, among which we further explored packet error rate and frame error rate that can be a reference for future WBAN studies.","PeriodicalId":314150,"journal":{"name":"2017 International Conference on Computer, Information and Telecommunication Systems (CITS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114264300","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}

Additionally, other factors like intermittent connections, limited bandwidth etc. further restrict the performance of existing routing protocols. In this paper, an advanced context aware routing protocol called GAP is proposed. The proposed protocol efficiently combines the benefits of Genetic Algorithm and Probabilistic Routing to route the message from the source to destination. The protocol uses the Genetic algorithm to predict the path a message would take if it is transferred to the neighbouring node. A Fitness function is defined to evaluate the efficiency of this predicted path. The message is transferred to the neighbouring node only if the fitness value of the predicted path is greater than a threshold value, which is calculated by implementing the concepts of probabilistic routing. Simulation results show that the GAP routing protocol outperforms Prophet, Spray and Wait and GAER protocol in terms of message delivery ratio, overhead ratio and average latency.","PeriodicalId":314150,"journal":{"name":"2017 International Conference on Computer, Information and Telecommunication Systems (CITS)","volume":"32 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132502236","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}

Disasters may cause severe damage to network components (links/nodes) and drastic traffic fluctuations in post-disaster phases, leading to resource crunch. In this paper, we study optimal traffic re-provisioning under resource crunch and propose a hierarchical fairness based re-provisioning (HFR) scheme to maintain service connectivity and balance traffic flow in post-disaster optical networks. By exploiting a multistage re-provisioning process and a cyclic re-provisioning process, HFR can effectively maintain service connectivity and achieve a hierarchical fairness on traffic distribution. Numerical results show that, the proposed HFR, compared with some counterparts, can obtain satisfactory performance in terms of connection loss ratio, traffic loss ratio, and fairness of traffic distribution.","PeriodicalId":314150,"journal":{"name":"2017 International Conference on Computer, Information and Telecommunication Systems (CITS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125223239","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 main categories of CF have their own shortcomings. Memory-based CF can't generate accurate results when faced with data sparsity; and model-based CF always loses the information between users or items. To alleviate this problem, we propose an algorithm that integrate user trust into the traditional matrix factorization (MF). Trust network is introduced to utilize all the trusted users to help make prediction. Experiments are performed on Epinions dataset and FilmTrust dataset to compare proposed approach with traditional ones. The reported results indicate that the idea of employing user trust into MF is valid and can improve the recommendation quality.","PeriodicalId":314150,"journal":{"name":"2017 International Conference on Computer, Information and Telecommunication Systems (CITS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134487471","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}

In this transmission scene, we study the problem of maximizing the network throughput and minimizing the mean delivery delay per packet. Then we propose a greedy scheduling (GS_Cellular&D2D) algorithm, which jointly selects the transmit device and schedules the coded packet transmitted from the BS and selected device at each time slot in order to maximize one time step future-reward. As contrast, we also analyze another two algorithms: ARQ_Cellular&D2D and RNC_Cellular&D2D.

Implant devices are widely employed to measure physiological signals inside the human body in a simple, long lifetime and continuous approach. However, due to the strict technical requirements of implant devices, there exist numerous key research challenges in this area. Considering realistic transmission power requirements based on the IEEE 802.15.6 standard safety regulations, the channel characteristics of implant to deep implant and implant to body surface communication scenarios are investigated. Furthermore, multiple vital quality of service (QoS) factors of implant communication channels are studied regarding channel capacity, bit error rate (BER), link quality and data rate. The system performance evaluation indicates that the data transmission rate can be optimized up to 10 Mbps. Furthermore, the transmission distance supported by in-body to on-body communication path is 2 meters, at 1 µW while the in-body to deep tissue region communication channel achieves less than 1 meter. The results proposed in this paper give an outlook of the intra-body networking system performance and can be applied to in-body communication system implementation research.","PeriodicalId":314150,"journal":{"name":"2017 International Conference on Computer, Information and Telecommunication Systems (CITS)","volume":"23 7","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132388780","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, a severe problem Internet Water Army (a large amount of paid posters who write inauthentic reviews) emerge in many E-commerce websites recently which dramatically undermines the value of user reviews. Although the word Internet Water Army originated from China, some other countries also suffered from this problem. Many organized underground paid poster groups found it extremely profitable to mislead the consumers by writing fake reviews. It had become more and more challenging to accurately detect the water army who could alter their writing style. In this paper, we design a comprehensive set of features to compare paid posters against normal users on different dimensions. Then we build an ensemble detection model of seven different algorithms. Our model has reached 0.726 in AUC measure and 0.683 in F1 measure on JD dataset, 0.926 in AUC measure and 0.871 in F1 measure on Amazon dataset, which outperforms previous studies. Our work provides some practical solutions and guidance to this severe problem for the whole E-commerce industry.","PeriodicalId":314150,"journal":{"name":"2017 International Conference on Computer, Information and Telecommunication Systems (CITS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126125439","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}
