Scheduling algorithms to provide QoS support for wireless networks and multimedia applications with real-time constraints
Gabriele Cecchetti is investigating the problem of QoS and Real-Time guarantees provisioning over IEEE 802.11e networks [paper J03]. He has proposed some scheduling algorithms alternative to the reference scheduler of HCCA IEEE 802.11e networks. In particular he has proposed Wireless Capacity-Based Scheduler (WCBS) [papers J01, C16, C015], its improved version with Resource Reservation (WCBS-R), [paper BC03], Unused Time Shifting Scheduler (UTSS) [paper C20] and Immediate Dynamic TXOP HCCA (IDTH) [paper C21]. Moreover he has proposed an enhanced scheduler using the HCCA-EDCA Mixed Mode (HEMM) in IEEE 802.11e networks, Overboost, [papers J02, C17]. A further scheduler algorithm based on a feedback mechanism is under submission.
Cross-layer framework for QoS support in wireless networks
Gabriele Cecchetti has proposed a contract-based framework and a middleware software to manage QoS application requests which want to deal with underlying network layer. The framework is ruled by the QoS Manager [papers C12, C13, C14].
Study and performance evaluation of scheduling algorithms for heterogeneous networks
Secure radio system for efficient rail traffic
He coordinated the developement project of the full software system of EuroRadio protocol for the European Rail Traffic Management System (ERTMS). Moreover he has oversaw the functional testing activity and the conformity to the CENELEC software security standard.
