A proposal of a heuristic QoS multicast routing for multi-layer wireless architecture
Nunzia Palmieri, Abdon Serianni · 2022
Multicast services are a one-to-many communication typology representing an important user services technique mostly used for those networks naturally broadcast. The nodes in the network have to send explicitly join and leave messages in order to participate in the multicast communication using the well-known Internet Group Management Protocol (IGMP). This paper focuses on the introduction of a multicast paradigm on a hybrid multi-layer wireless system. The protocol used is the Core Based Tree (CBT) with the introduction of QoS requirements in order to guarantee the constraints required by the users. A precise scenario has been considered and, for the simulation campaigns an ad-hoc simulator developed in java language has been used. Finally, the obtained results for the considered scenario have been described.
