In this paper, mobile multicast mechanism based on IEEE 802.21 MIH (Media Independent Handover) for efficient network resource usage is proposed. Proposed mechanism supports the efficiency of network resource usage and fast multicast handover. The proposed architecture adopts multicast manager concept to MIH framework in order to efficiently perform mobile multicast handover, and adds the new MIH...
In this paper fast mobile multicast mechanism based on IEEE 802.21 MIH (Media Independent Handover) is proposed. We solve long multicast handover delay time caused by L3 movement detection mechanism of the existing mobile multicast methods. The proposed architecture adopts multicast manager concept to MIH framework in order to efficiently perform mobile multicast handover, and adds the new MIH messages...
Internet protocol television (IPTV), one of the most emerging services, offers multimedia streaming services with security, reliability, and relevant quality of service (QoS)/quality of experience (QoE). It provides added values to all the involving players including customers and also brings technical and business challenges to those players. For IPTV services, we expect to adopt the next generation...
Conventional multicast group communications need a dynamic mechanism for group management according to the join/leave of receivers and for the modification of membership information and a QoS management for a reliable multicast group communication. The Group Management Protocol (GMP) is an application-layer control protocol to supports the group management and the membership management for the multicast...
IPTV service offers multimedia streaming services with security, reliability, and relevant quality of service (QoS)/quality of experience (QoE). It provides technical and business challenges to customers as well as network/service providers. It expects that the next generation network (NGN) environment provides the transport platform with high quality and high performance for IPTV services. The Web...
Cell sectorization and improvement of the Ec/Io are technologies to offer good quality of services (QoS) and coverage for new and sophisticated power control to achieve high capacity in CDMA cellular mobile communication networks. In this paper, in order to efficient cell sector and to improve the Ec/Io of the pilot channel in CDMA mobile communication systems, I analyze and compare the wide- beam...
