Abstract

A common concern in smart cities is the focus on sensing procedures to provide city-wide information to city managers and citizens. To meet the growing demands of smart cities, the network must provide the ability to handle a large number of mobile sensors/devices, with high heterogeneity and unpredictable mobility, by collecting and delivering the sensed information for future treatment. This work proposes a multi-wireless technology communication platform for opportunistic data gathering and data exchange with respect to smart cities. Through the implementation of a proprietary long-range (LoRa) network and an urban sensor network, our platform addresses the heterogeneity of Internet of Things (IoT) devices while conferring communications in an opportunistic manner, increasing the interoperability of our platform. It implements and evaluates a medium access communication (MAC) protocol for LoRa networks with multiple gateways. It also implements mobile Opportunistic VEhicular (mOVE), a delay-tolerant network (DTN)-based architecture to address the mobility dimension. The platform provides vehicle-to-everything (V2X) communication with support for highly reliable and actionable information flows. Moreover, taking into account the high mobility pattern that a smart city scenario presents, we propose and evaluate two forwarding strategies for the opportunistic sensor network.

摘要

智慧城市中的一个常见问题是专注于传感程序，以便向城市管理者和市民提供全市范围的信息。为了满足智慧城市不断增长的需求，网络必须具备处理大量移动传感器/设备的能力，这些设备具有高度的异构性和不可预测的移动性，通过收集和传递传感信息以供未来处理。这项工作提出了一个用于智慧城市的机会性数据收集和数据交换的多无线技术通信平台。通过实施专有远程（LoRa）网络和城市传感器网络，我们的平台解决了物联网（IoT）设备的异构性问题，同时以机会性方式进行通信，提高了我们平台的互操作性。它实现并评估了一种用于具有多个网关的LoRa网络的介质访问通信（MAC）协议。它还实现了移动机会车辆（mOVE），这是一种基于延迟容忍网络（DTN）的架构，用于解决移动性问题。该平台提供车辆到万物（V2X）通信，支持高度可靠且可操作的信息流。此外，考虑到智慧城市场景呈现的高移动性模式，我们提出并评估了机会性传感器网络的两种转发策略。
