Abstract

The multicast facilitates group communications in IP networks and largely improves the usage efficiency of the bandwidth. However if this transmission technology has reached a sufficient maturity in fixed networks, it results in many problems in an IP environment where the receiver is mobile. The problem is partially attributable to the protocols managing the host mobility. Indeed, in the mobile Internet, the host mobility affects unicast addresses which are considered in the multicast routing protocols as stable. So the change of these unicast addresses lead to long handover latency and packets losses due to interruptions provoked by the mobility. So, the best adaptation of the multicast in the mobile Internet depends strongly on the type of mobility protocol in use. The current propositions for applications of multicast services are made in the mobility environments offering mobility management insufficiently optimized according to the following essential performance criteria: improvement of the handover latency, the scalability and the packet loss rate. Our proposal, based on the NC-HMIPv6 protocol, offers a better mobile multicast management through leaning the possibilities offered by this protocol. By widening the features of various entities in the NC-HMIPv6 environment, an effective management of the multicast handover is proposed.
