MQTT Pub-Sub Service for Connected Vehicles

Abstract

MQTT is a popular publish-subscribe service used by IoT applications. Vehicular networks are heterogeneous wireless networks that provide diverse applications QoS requirements. Maintaining connection with the MQTT brokers is a challenge for moving vehicles. In this paper, we explore an NDN access network for vehicular networks connected with mobile edge cloud. We proposed a design of MQTT pub-sub on a distributed vehicular NDN network that deploys MQTT proxy and in-network caching. We implemented our design using Python MQTT client and open source NDN FD.
