However, these existing flooding trees normally could not achieve low latency and high energy efficiency at the same time which is critical to data transmission, especially in low-duty-cycle WSNs with unreliable wireless links. In this work, we propose an efficient local energy optimization algorithm (LEOA) for minimum-delay flooding tree in synchronous low-duty-cycle WSNs. Through adjusting the tree structure locally, LEOA can reduce energy consumption while not increasing flooding delay. Our design fully utilizes the broadcast nature of wireless networks, with considering the unreliability of wireless links. Extensive simulation results indicate that LEOA outperforms state-of-the-art methods in terms of flooding delay and energy efficiency.","PeriodicalId":422906,"journal":{"name":"2014 IEEE Computers, Communications and IT Applications Conference","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125352672","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}

Mining sentiment information behind these data helps people know about public opinions and social trends. In this paper a sentiment analysis algorithm adapting to Weibo (Microblog) data is proposed. Given that a Weibo post is usually short, LDA model is used to generate text features based on semantic information instead of text structure. To decide the sentiment polar and degree, SVR model is used here. Experiment shows the algorithm performs well on Weibo data.","PeriodicalId":422906,"journal":{"name":"2014 IEEE Computers, Communications and IT Applications Conference","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122374369","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}

Theory analysis showed than the shorter of the average length of the routes of the P2P services, the higher of the system throughput. By offering the P2P services with short length of route high priority to access the channels, the proposed algorithm could improve the network throughput and guarantee the Quality of Service (QoS) of P2P service in the network.

In this paper we propose a robust fingerprint method for localization based on the traditional K-Nearest Neighbor (KNN) method. Instead of considering a fixed number of neighbors, our approach uses an adaptive method to determine the optimal number of neighbors to be taken into account.. In order to prove the effectiveness of our method, we compare it with the traditional KNN approaches for a variety of number of Access Points (APs). Simulation results using Multi-Wall-Floor path loss model show that the proposed method yields an improved accuracy as compared with the traditional methods.","PeriodicalId":422906,"journal":{"name":"2014 IEEE Computers, Communications and IT Applications Conference","volume":"303 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128626116","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 order to achieve multipath transmission, data center uses Equal Cost Multipath (ECMP) algorithm to forward flows. ECMP algorithm is lack of dynamic scheduling mechanism. In this paper, we completed a full implementation of three scheduling algorithm in the data center network of SDN architecture. One is based on OSPF algorithm. The second is based on ECMP algorithm. In the third algorithm, we optimized the ECMP algorithm through OpenFlow protocol and made it possible to dynamically adjust the flow forwarding link according to the bandwidth utilization of core links.

How to choose an appropriate opportunity to forward data is pivotal for nodes' routing in this type of networks. Since nodes currently will keep a regular movement state in the scene of this paper discussed, forecasting a node's moving track in the near future would be very helpful. Through this way, the node can modify the forwarding strategy in time and increase the success rate of data routing. We proposed a path prediction model based on second-order Markov chain in this paper to analyze and predict node's next path choice at an intersection depending on its statistic of history tracks. Then we use the real data from Dartmouth College to verify the model and the result shows that it is more precise than normal one step Markov models and is more reasonable than some other models such as Manhattan model.","PeriodicalId":422906,"journal":{"name":"2014 IEEE Computers, Communications and IT Applications Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114598364","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}
