چکیده

Event-driven programming has emerged as one of the mainstream paradigms for the engineering of distributed applications assembled out of loosely related software components. In this paper, we present our on-going research in the development of a flexible event-dissemination framework targeted at mobile and stationary computing environments. We discuss a solution based on virtual multicast event channels, where protocol heterogeneity support and active routing over a network of servers are advocated as a flexible answer to the challenges posed by disconnection and variable connectivity constraints.

Resilience Enhancement of Active Distribution Networks Via Mobile Energy Storage Systems and Protection Coordination Consideration

Owing to the portability and flexibility of mobile energy storage systems (MESSs), they seem to be a promising solution to improve the resilience of the distribution system (DS). So, this paper presents a rolling optimization mechanism for dispatching MESSs and other resources in microgrids in case of a natural disaster occurrence. The proposed mechanism aims to minimize the total system cost b...

Sink-oriented Dynamic Location Service Protocol for Mobile Sinks with an Energy Efficient Grid-Based Approach

Sensor nodes transmit the sensed information to the sink through wireless sensor networks (WSNs). They have limited power, computational capacities and memory. Portable wireless devices are increasing in popularity. Mechanisms that allow information to be efficiently obtained through mobile WSNs are of significant interest. However, a mobile sink introduces many challenges to data dissemination...
