Exploring Medium Access Control protocols in an embedded device

Abstract

The number of internet-connected devices is increasing substantially. Of these devices, a significant portion is embedded devices. In order to maintain such vast amounts of connections, and in order to ensure that the quality of these connections remains stable, a robust set of standards and protocols is required. The Open Systems Interconnection reference model is a common framework used by device designers and manufacturers, in order to standardize communication protocols. Defined as part of the Open System Interconnection model is the Medium Access Control layer, which helps define the protocols necessary for data transmission and receiving at a device level.

This work’s objective was to explore the functionality and implementation of those protocols defined in the Medium Access Control layer, with specific emphasis on embedded devices. Exploration into these protocols was carried out by defining the operating environment, and based on these definitions, a test setup was designed to emulate real-world circumstances. This test setup aimed to include the multiple aspects required in implementing Medium Access Control protocols in embedded devices. Based on the findings of this thesis, it could established that designing a test setup promoted the stated objectives, and further exploration can be achieved by implementing the designs proposed in this thesis
