Performance evaluation of using Protocol Buffers in the Internet of Things communication

Things connected to the internet may not be connected only to servers on the cloud. Its usefulness can be unleashed only if they are interconnected as well. This interconnection is recognized as communication between services of the Internet of Things. Due to the nature of the things on the web, spatial overhead for any data exchanged needs to be kept to a minimum. JSON is recognized as a most efficient way to transfer various data in domain of distributed embedded systems. JSON's binary representation, BSON is even more preferable. This paper explores the possibilities and critically examines and evaluates the effectiveness of using Google's Protocol Buffer as a processing protocol and communication standard in transportation domain of the Internet of Things.

I. Introduction

Increasing the number of devices connected to a global network, the scope of embedded systems expands. This requires, a simple but feasible message format for the data exchange [1]. These devices are not only used to provide data but also services. This means that web services are already merging with embedded devices.
