Extended optimisation mechanism for radio resource allocation in multicast mobile networks

Abstract

Mobile communication paradigm has shifted from a closed network of transmitters and receivers to an access network transporting what the content providers have to offer. Many existing and future applications offer the same content to most, if not all, clients. These applications include crowdsensing, news, and traffic monitoring portals. Mobile operators would largely benefit if such applications use multicast messages instead of unicast. Multicast communication suits such applications, but in some scenarios its efficiency can drop to reach that of unicast. In this work, we will propose a mechanism to optimise the allocation of radio resources when used for multicast, thus offering the mobile operator an opportunity to increase profit without affecting user satisfaction. The performance of the proposed mechanism is measured for various simulation scenarios.
