Abstract The present study regards the creation of a support model for access control and optimization of cargo loading at ports. It aims to minimize the deficiencies of port accesses and to optimize shipping rates, using an algorithm to create virtual queues and use Radio Frequency Identification (RFID) technology. The theoretical approach and some of the data reported in this paper came from a master’s degree research project of one of the authors, through the Civil Engineering Graduate Program at the Federal University of Santa Catarina. The port chosen for implementing the proposed model was the Porto de Vitória, one of the busiest transportation terminals in Brazil. Initially, a survey was carried out locally and the data collected were tabulated to be used in a simulator. The results show the effectiveness of the model based on the use of a simulation system (Arena®). The applied model helps to avoid traffic jams in the port area and also allows the automation of port access.

The Given

With the rapid development of wireless communications for network of things, more and more models for such networks-on-chip architectures have been created and used in a wide range of applications. In this article, the behaviors of wireless communications for such networks-on-chip architectures are analyzed at two layers. The physical layer behaviors consist of what frequency is used, how and when signals are transmitted, and how transceivers’ responses are decoded. The medium access control layer behavior consists of how to provide a reliable link between two peer medium access control entities. For the optimization objective of each layer, the specific problems surrounding the design of combined radio frequency identification/Bluetooth/Wi-Fi chips are considered at their respective layer, and then, corresponding optimization methods are carried out. The problem of optimization is defined as a linear programming problem in which each active transceiver is assigned to a channel on condition that all the constraint is met on every link. Each optimization procedure proposed in this article is performed through the adaptation of its objective, from each one of these layers, in order to minimize interference previously specified. In principle, the optimization can be made layer by layer separately. The optimization criteria consist of a specification of the behaviors of wireless communications (radio frequency identification, Bluetooth, Wi-Fi) and a set of constraints and goals. Our approach is to perform it independently within the given task, where the given task can be achieved with its sequencing graph entities, including automate selection, binding, and scheduling. We have implemented our algorithms on a field-programmable gate array and applied them to some off-the-shelf products. This methodology looks promising, not only for the results presented and obtained through computer simulations but also for its generality concerning to the kind of wireless network system used. Therefore, such methodology is expandable either to multi-core networks-on-chip architecture or also to the off-the-shelf products.
