| Resumo: | Wireless Communication is a trend in the industrial environment nowadays and on
this trend, we can highlight the WirelessHART technology. In this situation, it is natural
the search for new improvements in the technology and such improvements can be related
directly to the routing and scheduling algorithms. In the present thesis, we present a
literature review about the main specific solutions for Routing and scheduling for WirelessHART.
The thesis also proposes a new scheduling algorithm called Flow Scheduling
that intends to improve superframe utilization and flexibility aspects. For validation purposes,
we develop a simulation module for the Network Simulator 3 (NS-3) that models
aspects like positioning, signal attenuation and energy consumption and provides an link
individual error configuration. The module also allows the creation of the scheduling superframe
using the Flow and Han Algorithms. In order to validate the new algorithms,
we execute a series of comparative tests and evaluate the algorithms performance for link
allocation, delay and superframe occupation. In order to validate the physical layer of
the simulation module, we statically configure the routing and scheduling aspects and
perform reliability and energy consumption tests using various literature topologies and
error probabilities. |
