A scalable scheduling model is needed to adapt to various energy sources and operating conditions. This paper proposes a conditional random field (CRF) method to analyse the intrinsic characteristics of energy hub scheduling problems. Building on these characteristics, a reinforcement learning (RL) model is designed to strategically schedule power and natural gas exchanges as well as the energy dispatch of energy hub. Case studies are performed by using real-time digital simulator that enables dynamic interactions between scheduling decisions and operating conditions. Simulation results show that the CRF-based RL method can approach the theoretical optimal scheduling solution after 50 days training. Scheduling decisions are particularly more dependent on received price information during peak-demand period. The proposed method can reduce 9.76% of operating cost and 1.388 ton of carbon emissions per day, respectively.","PeriodicalId":252172,"journal":{"name":"2019 IEEE/CIC International Conference on Communications Workshops in China (ICCC Workshops)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124045489","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}

With the popularity of mobile devices, large volumes of data about people and their locations are gradually accumulating at mobile base stations. In this study, we used such call details records (CDR) and long short-term memory (LSTM) networks—a kind of recurrent neural network (RNN) —to predict the future traffic of a base station. By implementing gate mechanism, the LSTM can solve the problem of exploding and vanishing gradients of ordinary RNNs. We use a sliding-window approach to transform the problem of time series forecasting into a supervised learning problem. Then, we use the proposed deep LSTM network to model the traffic of base stations, which enables the prediction of future traffic and the generation of the heat map of a city. The method we presented can decrease the root mean square error (RMSE) of the predicted access time down to 23.34 minutes per hour per base station.","PeriodicalId":252172,"journal":{"name":"2019 IEEE/CIC International Conference on Communications Workshops in China (ICCC Workshops)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124053572","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 limited spectrum resource becoming more and more crowed to meet different requirements. To improve the limited transmission resource (spectrum, time, power etc.) utilization while meet the different needs of users, we introduce the reward function as a measure of different allocate policies. Then we calculate the reward that different allocation policies might gain. The arrived state is a Markov Process which means the next coming state is only determined by the current state. To solve the optimization problem, we introduce the Q-Iearning algorithm. Due to the state space is enormous, this paper strives to illustrate a DQN (Deep Q-Network) based resource allocation algorithm.

We study the outage performance of one-way DF relaying network over log-normal fading channels, which are applicable to the indoor environment. We analyse the performance of the proposed scheme under the conditions considering the statistical or instantaneous channel state information (CSI). Analytical expressions of outage probability and achievable throughput are derived based on the statistical CSI, furthermore, we can get the optimal time switching factor and power splitting factor. For the instantaneous CSI, the power splitting factor is optimized to minimize the outage probability. In order to find the optimal time switching factor, a bisection iteration method is adopted. The simulation results show that the outage probability and throughput of the hybrid protocol outperform the existing power splitting-based relaying (PSR) scheme.","PeriodicalId":252172,"journal":{"name":"2019 IEEE/CIC International Conference on Communications Workshops in China (ICCC Workshops)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134038836","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}

To achieve a sophisticated dynamic spectrum access, understanding the spectrum usage is an important task. We focus on duty cycle (DC) as a feature quantity of spectrum usage in the time domain and observed DC (O-DC) obtained from long-term spectrum measurement results is used for the modeling. In fact, O-DC has stochastic and deterministic behaviors and we have been investigated modeling for both behaviors. O-DC is stochastic behavior and a mixture distribution based modeling has been considered for the model of stochastic behavior. We employ nonparametric Bayesian model (NPBM) in which the number of distributions is also an adjustable parameter. Statistics of O-DC, such as mean of O-DC, has a deterministic behavior in time domain. Specifically, the deterministic behavior is determined by the common daily habits, such as mean of O-DC during is night is low, but it is high during daytime. We show the validity of the stochastic and deterministic model for O-DC based on long-term spectrum measurement results.","PeriodicalId":252172,"journal":{"name":"2019 IEEE/CIC International Conference on Communications Workshops in China (ICCC Workshops)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114668054","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 carbon intensity of electricity varies throughout the day as a result of emissions released during generation. These fluctuations in carbon intensity are predicted to increase due to increased penetration of variable generation sources. This paper proposes a novel insight into how reductions in domestic emissions can be achieved, through the scheduling of certain wet appliances to optimally manage low carbon electricity. An appliance detecting and scheduling algorithm is presented and results are generated using real demand data, electricity generation and carbon intensity values. Reductions were achieved from the variations in grid carbon intensity and the availability of solar generation from a household photovoltaic (PV) supply.","PeriodicalId":252172,"journal":{"name":"2019 IEEE/CIC International Conference on Communications Workshops in China (ICCC Workshops)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131960120","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}
