Optimization of a CSMA/CA based MAC protocol designed for confined WSNs

Résumé

The need for control of human activities has fueled the development of networks built using small modules with low power-consumption and providing reliable data transmission. The OCARI project's goal was to develop one such network specifically targeted towards confined environments : submarines, power plants... . In this paper, we focus on this project's MAC layer, MaCARI, and its mechanisms for time-constrained traffic. We examine the performance of the CSMA/CA protocol used in the contention-access period as the GTS' size varies. Prototyping and simulation are used in order to propose how the Guaranteed Time Slots should be allocated without hindering the network's performance.
