ABSTRACT

Since multicast in the mobile environments is based on packet transmission and independent addressing, this paper propose an improved scheme about how to manage the multicasting group and to set the communication path in the mobile environment by applying two-level addressing mode, which is similar to mobile IP, for location-independent address setting. And we propose the smooth handoff scheme that minimizes the handoff delay for mobile multimedia services. Performance analysis by the modified NS-2 network simulator has showed that the proposed scheme is better than other techniques in terms of handoff delay and transmitted packets' throughput.
