This paper presents a stochastic method for an electric vehicle (EV) aggregator to coordinate EV charging schedule considering uncertainty in EV departures. The EV aggregator is responsible for managing the charging schedule of EVs while participating in the electricity markets. The managed EV charging can provide additional revenues to the aggregator from regulation market participation and ch...

One of the most natural and primary ways of data collection in wireless sensor networks is to periodically report sensed data values from sensor node to aggregator. However, this kind of data collection mechanism comes at the cost of power consumption and packet collision. In this paper, we developed an automatic ARIMA (Auto Regressive Integrated Moving Average) modeling based data aggregation ...

We consider applications scenarios where an untrusted aggregator wishes to continually monitor the heavy-hitters across a set of distributed streams. Since each stream can contain sensitive data, such as the purchase history of customers, we wish to guarantee the privacy of each stream, while allowing the untrusted aggregator to accurately detect the heavy hitters and their approximate frequenc...

In order to reduce number of data transmissions and improve the bandwidth and energy utilization in wireless sensor networks (WSNs), data aggregation or in-network processing techniques are needed. The simplest way to achieve data aggregation is to select data aggregator nodes. In this paper, we investigate optimal aggregator node selection in WSNs. The main idea of our approach is to perform a...

Demand-Side Management (DSM) programs consider the energy consumers as intelligent agents and as key players for system management, gaining importance on the Smart Grid era. In this context, we propose a cooperative approach for the decision-making process of an aggregator that represents a group of residential consumers in a DSM program. The aggregator participates in a day-ahead market and ha...

The close interaction between the electricity market and end-users can assist demand response (DR) aggregator in handling managing various uncertain parameters simultaneously to reduce their effect on aggregator's operation. As DR main responsibility is aggregate obtained from individual consumers trade it into wholesale market. Another of proposing programs (DRPs) end-users. This article propo...

We consider the distribution of channels of live multimedia content (e.g., radio or TV broadcasts) via multiple content aggregators. In our work, an aggregator receives channels from content sources and redistributes them to a potentially large number of mobile hosts. Each aggregator can offer a channel in various configurations to cater for different wireless links, mobile hosts, and user pref...

Electric vehicle (EV) aggregator, as an agent between the electricity market and EV owners, participates in the future and pool market to supply EVs’ requirement. Because of the uncertain nature of pool prices and EVs’ behaviour, this paper proposed a two-stage scenario-based model to obtain optimal decision making of an EV aggregator. To deal with mentioned uncertainties, the aggregator’s risk...

In the demand side management (DSM) the aggregator is appearing as a key player in managing the demand during the peak hours by acting as an energy manager between the utility and the consumer. In this work, an emerging concept of the energy service provider as a business entity for domestic consumers is discussed and focuses on the interactional issues between the utility, the aggregator and t...
