Thesis type RESEARCH THESIS

Description This thesis is about the use of wireless techniques based on IEEE 802.11g standard (and newest ones) in order to support industrial real-time communications. Indeed, there is a strong interest in industry in the use of wireless devices for the communication between controllers and actuator devices (e.g., industrial robots). A techniques to increase transmission determinism and dependability is to transmit a duplicated frame on more than one channel. This technique, in order to improve performance, requires some modification to the IEEE 802.11g protocol. The purpose of this thesis is the modification of the models of a network simulator in order to compare different techniques based on redundancy with respect to classical models. Eventually, a prototypal implementation may be obtained using a Linux based operating system.

Required skills Good knowledge of the C programming language, basic knowledge of the most important network protocols (Ethernet, IP, TCP, UDP and possibly IEEE 802.11g).

Notes The thesis work will be done in the IEIIT institute of the CNR (National Research Council of Italy) which is inside the Politecnico di Torino
