Abstract
Low-power wireless networks allow for easy-deployment and low-maintenance
solutions for sensor applications. Glossy, an often used communication primitive
to build such low-power wireless networks, is a flooding protocol providing high
reliability and resilience. Even though the list of protocols building on top of
Glossy is extensive, the current approach to implement Glossy-based protocols
could be significantly improved by separating low-level complexity from high-
level protocol logic.
The Glossy Middleware presented in this thesis provides system designers
with a well-defined, yet versatile interface. Building on top of a round-based
framework, the Glossy Middleware offers a vast amount of control over important
Glossy parameters on a high-level.
This report presents the design and features of the Glossy Middleware in
detail, while also serving as an user manual. The evaluation displays the low
performance overhead in terms of memory and energy usage as well as the high
usability by reimplementing different existing protocols in addition to others,
illustrating the various features of the middleware. The middleware has been
designed with hardware portability in mind: currently it is fully supported on
the DPP platform and to some extent on the TelosB platform.
This thesis concludes by illustrating possible improvements on the existing
work while also outlining exiting possibilities of the developed Glossy Middle-
ware.
