چکیده

The Energy Harvesting Roadside Unit (EH-RSU) with self-powered module will not only effectively reduce the communication load of regional Vehicular Ad Hoc Networks, but also enjoys a low deployment cost. Given imbalance in demands invoked by transportation systems, EH-RSU should allocate energy appropriately accordance its harvesting rate to ensure safety vehicles within coverage. Firstly, we propose novel attention-based spatial-temporal graph convolutional network (ASTGCN) predict around road through surrounding vehicle information. Secondly, use predicted as part input parameters neural and leverage double deep Q ameliorate operating states switching strategy EH-RSUs reinforcement learning so that they achieve more satisfying effective time limited resources. Finally, built dataset simulation validate effectiveness our model. results show prediction model has better accuracy improved higher efficiency compared other methods.

Stochastic Routing and Scheduling Policies for Energy Harvesting Communication Networks

In this paper, we study the joint routing-scheduling problem in energy harvesting communication networks. Our policies, which are based on stochastic subgradient methods on the dual domain, act as an energy harvesting variant of the stochastic family of backpresure algorithms. Specifically, we propose two policies: (i) the Stochastic Backpressure with Energy Harvesting (SBP-EH), in which a node...

Service Scheduling of Vehicle-Roadside Data Access

As vehicular networks become popular, more and more people want to access data from their vehicles. When many vehicles want to access data through a roadside unit, service scheduling becomes an important issue. In this paper, we identify some challenges in vehicle-roadside data access. As vehicles move pretty fast, the requests should be served quickly. Also, vehicles may upload data to the roa...

Energy Propagation in Deep Convolutional Neural Networks

Many practical machine learning tasks employ very deep convolutional neural networks. Such large depths pose formidable computational challenges in training and operating the network. It is therefore important to understand how many layers are actually needed to have most of the input signal’s features be contained in the feature vector generated by the network. This question can be formalized ...
