This paper proposed an optimization strategy for EVs to travel more efficiently called planed ordered charging (POC for short), that is, spending more time on driving and necessary charging instead of waiting or overcharge. An energy reachable graph is built firstly to protect vehicles from breaking down in the midway. Travel time, including driving time, charging time and waiting time, is taken as the optimization goal. The modeling and solution of travel time is presented. One of the most important contributions of this paper is the proposal of charging station load and how it can be calculated, which well describes waiting time from a macro view. Besides, reservation mechanism for charging is also introduced to achieve the global optimization. Then the planning of efficient travel can be converted to a general graph theory problem by putting time cost onto edge weight of the graph. According to the simulation and experiment, the strategy proposed in this paper is superior to other compared strategies in many aspects.","PeriodicalId":393593,"journal":{"name":"2014 Asia-Pacific Services Computing Conference","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133906148","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 proposed scheme consists of a subcarrier pairing and selection algorithm and a power allocation algorithm. We first formulate the JS2PA problem as a mixed integer programming problem aiming to maximize the total network utility under the constraints of the total and individual power, subcarrier fairness requirement and pairing. To solve the non-convex JS2PA problem, firstly, we propose a subcarrier pairing and selection algorithm based on Hungarian method so as to select the appropriate subcarrier pairs for relaying. Secondly, we provide a power allocation algorithm based on the IWD method (PA-MIWD) in which water drops act as the agents to find the optimal power allocation for each node. Finally, we conduct simulations to validate the proposed algorithms and the results show that the proposed JS2PA scheme outperforms the existing methods in terms of convergence and total network utility.","PeriodicalId":393593,"journal":{"name":"2014 Asia-Pacific Services Computing Conference","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130134865","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}

Traffic sensory data gathered by large amounts of sensors show the massive, continuous, streaming and spatio-temporal characteristics compared to traditional traffic data. In order to satisfy the requirements of different applications with these data, we need to have the capability of processing both real-time traffic sensory data in streaming way and historical traffic sensory data in large amount. In this paper, we present an approach and corresponding system for traffic sensory data processing, which is designed to combine spatio-temporal data partition, parallel pipeline processing and stream computing to support traffic sensory data processing in a scalable architecture with real-time guarantee. Three types of applications in real project are also described in detail to show the significant effect gains of the proposed approach and system. Numerical evaluations according to experiment results also show that the system can gain high performance in terms of the processing time of traffic sensory data stream.","PeriodicalId":393593,"journal":{"name":"2014 Asia-Pacific Services Computing Conference","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128581143","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}

Existing context-aware Web services recommendation methods directly use context as a \"filter\" to discard services that may conflict with the current user's preference. However, the discarded services may be valuable for another user or for the same user under a new context, as one man's trash may be another's treasure. We assume that failing to handle the contextual reasons behind the user preference may introduce inaccurate recommendation, and even significant biases in recommendation. In this work, we propose a novel method dubbed CASR-UP, which aims to exploit the contextual factors of the user preference to improve Quality of Service (QoS) prediction and services recommendation accuracy. Our method consists of three stages: 1) context-aware similarity mining to get the set of users having similar context with the current user, 2) data filtering based on user preference in current context so as to get the invocation records of the services corresponding to the current user's preference, 3) Web services QoS prediction, recommendation and evaluation by Bayesian Inference. Experimental results on WS-Dream dataset is evaluated by both RMSE and MAE. The results show the proposed method improves prediction accuracy and outperforms the compared methods.","PeriodicalId":393593,"journal":{"name":"2014 Asia-Pacific Services Computing Conference","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116076880","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}
