Lightweight Internet protocols for web enablement of sensors using constrained gateway devices

摘要

Lightweight Internet protocols are increasingly being used in ubiquitous environment in order to optimize the resource usage of a constrained device like a smart mobile gateway. This paper presents a study on the various such protocols to optimize the usage of energy, and network resources, computation cost of a constrained gateway device. Comprehensive analysis and feature wise categorization of existing dominant protocols, namely MQTT (message queue telemetry transport), CoAP (constrained application protocol) are provided here to achieve improved understanding of the existing issues and gaps in this domain. The present work further identifies the best suited application areas for each protocol based on the results corresponding to typical resource requirements and performance attributes. Finally our vision on the research scope is presented here mainly for optimization of energy usage.
