Abstract: Efficient encoding of data is an important part of projects in the Internet of Things space. Communication packets must be kept as small as possible in order to minimize the power consumption of devices. In this thesis, an automatic code generation tool, irpack, is proposed that will unify the way packets are defined across all future projects at Institute IRNAS. Using a schema, this tool generates source code of encoders and decoders in target programming languages. A schema evolution system is also defined, by which changes to packets can be compatible across multiple versions. The tool is then applied to a selection of past projects to gauge its usefulness. It is determined that irpack is able to encode the same data into a similar or smaller size packet, while also providing additional versioning information.Keywords: encoding/decoding, schema, schema evolution, bit packing, code generationPublished in DKUM: 31.01.2022; Views: 370; Downloads: 53 Full text (2,58 MB)
